OIL AND GAS RESOURCES OF QUEBEC PERMIT 514

GEOLOGY

SETTING. Permit 514 .(referred to below as PR 514) lies en-

tirely within L'Assomption county. It extends from the town of L'Assomption

westward for 18 miles to parts of the boundary between L'Assomption and

Terrebonne counties. Topographically the area is almost completely flat

(See Maps 2, 3, 4), and ranges in elevation from 50 feet above sea level

in the eastern part to 200 feet in the northern and western parts. The

Achigan river traverses most of the area, entering it just below St. Lin

at an elevation of about 175 feet above sea level and joining L'Assomption

river near the town of that name at about 75 feet above sea level. The

latter river leaves the area of PR 514 only a few feet below that elevation.

Other streams, in particular St. Esprit and Mascouche rivers, flow for only

a few miles within the area's boundaries. None of these streams is

navigable to anything larger than a canoe or rowboat.

There is only one feature that could be called a hill. Three

miles south of Pont Mousseau there is an elliptical area nearly a mile

long and half as wide with a summit 50 feet above the surrounding flat plain, and consists of what is probably modified ground moraine. The southern

boundary of this area cuts across the central part of this hill.

Almost all of the area lies within the band of Trenton Limestone as shown on Quebec Department of Natural Resources Map 1407 (Map 2, in pocket). The extreme eastern tip, consisting of somewhat less than half a square mile, is shown on that map to be underlain by Utica and Lorraine shales, although the latter formations do not outcrop here. The drift cover 2. is thick, especially near L'Assomption where it is on the average 100 feet

in thickness.

The average size of farms here is about 90-100 acres although

there is a tendency to increase the size with governmental assistance.

Most farms are narrow, rarely more than 1000 feet frontage, and usually go

back to range boundaries about one mile from the road. Ordinarily the

distal one quarter or rarely one third of a prosperous farm is woodland,

used almost wholly for domestic wood supply. The pattern of cultivated

land versus woodland is well shown on the topographic map in the pocket to

this report. All farms have service roads capable of supporting farm

vehicles running the length of the farm; these roads are rarely fit for farm

use before May first. The chief products are both natural and industrial

milk mostly trucked out of the county; cheese factories are few. Mixed

crops include wheat, oats, barley, both feed and silage corn. Truck

farming is an increasing occupation. A fair proportion of most farms is

given over to pastures.

ROCK EXPOSURES. Outcrops, all of Trenton limestone (except a

small occurrence of Utica shale and of igneous rock at L'Epiphanie), are

restricted almost wholly to river banks, and occur at L'Epiphanie only.

1) Along Achigan river at St. Roch de l'Achigan (Laurentides East map, in

pocket), where good exposures of the Tetreauville Formation (Upper Trenton)

can be seen for a mile and a half along the river banks. 2) A part of a

continuous outcrop of Deschambault limestone (Lower Trenton) a mile southeast

of St. Lin (Laurentides East map, in pocket) where, at the village itself

(Laurentides West map, in pocket), Black River beds outcrop beneath the

highway bridge, and Lower Trenton limestone continues downstream for a 3. mile, just crossing the western limit of PR 514. 3) Good exposures of

Tetreauville limestone (Upper Trenton) along St. Esprit river at and for a couple of miles downstream from Lawrence (Laurentides East map,

in pocket). 4) Along Achigan river at L'Epiphanie (Vercheres map, in

pocket), where Tetreauville limestone is overlain by Utica shale, and in a nearby quarry a thick sill of basic rock occurs close to the contact.

5) Small outcrops of Tetreauville limestone 2 miles north of L'Epiphanie

on St. Esprit river.

To be sure, beyond the limits of this permit additional outcrops

are known at Ste. Anne des Plaines (Bruchési, on Laurentides West map, in

pocket), St. Esprit (Laurentides East map, in pocket), Mascouche Rapids

(ibid.), in fields between St. Alexis (ibid.) and St. Jacques (ibid.), and

fine exposures along the Ouareau, Rouge, St. Pierre, and Assomption rivers.

These are sufficient in quantity, position, and nature to allow a dis-

tributional geological map to be drawn covering the area of PR 514 and

surrounding territories.

WELL LOGS. In addition there is a body of information from logs

of wells within and near PR 514. The locations of these are shown on the

geological map accompanying this report, and the logs are given in a

following appendix. Their names are given below, preceded by the number

assigned to them by the Quebec Department of Natural Resources as recorded

each is given in feet.

Of the above units, in addition to the overburden and igneous

rocks, only the Lower, Middle and Upper Trenton and the Utica are exposed.

All, however, have been cut by drill holes, as is shown in the log of Oil

Selections No. 6. In general increases in thickness are in the direction

of the axis of the Chambly-Fortierville syncline, but two prominent ex-

ceptions are the Potsdam and Beekmantown units, both of which pinch out toward the northeast, and neither reaches the St. Maurice river (55 miles to the northeast).

Each of the sedimentary groups is described below. 6.

POTSDAM SANDSTONE. Exposures of this formation are unknown within the limits of PR 514, but are abundant in the western part of the

Laurentides map area, and its presence 2 miles northeast of Ste. Julienne is indicated, in what is probably glacial drift, by a great abundance of large (up to 15 feet thick) blocks of this sandstone associated with only a few and smaller blocks of Precambrian. In well logs (Figure 2) it is recorded in the Quonto-International Mascouche No. 1 well (#58), and the

Oil Selections No. 6 well (#88), as well as in the Louvicourt Metal No. 8 l'Assomption well (#151). It is reasonable to expect that it will be found at the base of the Paleozoic section in any well drilled within this area.

It is divided into two formations. The lower, known as the Covey Hill

Formation, is conglomeratic at its base with boulders up to a foot in thickness, though pebbles up to an inch thick are most generally seen. The bulk of this member is a sandstone composed largely of quartz and possesses an all pervading matrix which prevents any but a minimal porosity to exist.

The remainder, the Chateauguay Formation, is a nearly pure quartz sandstone, containing very little matrix, with a resulting porosity which has allowed it to act as an aquifer in certain regions west of PR 514. Isopach studies of the Lowland region show that this upper part of the Potsdam sandstone

(Theresa and Cairnside members of the Chateauguay Formation) should be

100 feet thick in the northwestern part of the area increasing to 600 feet in the southeastern parts (Figure 3). Data are not abundant enough to allow the construction of an isopach map of the lower part of the Potsdam (Covey

Hill Formation), but it might range from a few hundred in the northwest to possibly one thousand feet in the southeast part of PR 514. In any probing for hydrocarbons the upper two or three hundred feet of Potsdam sandstone should be carefully scrutinized, and drilling should be carried down to Figure 2

the Precambrian basement so that any possible "granite wash" can be tested.

BEEKMANTOWN GROUP: (BEAUHARNOIS DOLOMITE FORMATION). This is a

light to medium gray rock nearly devoid of fossils, dense to crystalline

texture relieved in some beds by an abundance of vugs up to a few inches

across, filled partially or completely with carbonates. Some of these vugs

contain smears or complete layers of albertite or similar hydrocarbon

derivative. The vugs never produce an intercavity porosity and the dolomite

cannot be regarded with favor as a container of oil or gas. The rock could,

however, act as a roof-trap if appropriate porous structures in the under-

lying Potsdam Sandstone should exist. In thickness it probably ranges between

800 feet in the west to 500 feet in the east (Louvicourt Metal No. 8

l'Assomption (#151), 531 feet) .

CRAZY GROUP: LAVAL LIMESTONE FORMATION AND JOLIETTE MEMBER. Rocks

of this group do not outcrop in PR 514, but are known within a few miles of

Ste. Julienne (Laurentides East map, in pocket). No contacts with the

Beauharnois dolomite are known. At the base is a pure quartz sandstone

(the Joliette Member), well shown in drainage ditches near St. Alexis

Station, and a few miles further east in the bed of Assomption river at

Joliette (See Map 1407 in pocket). The percentage of quartz grains, for

the most part rounded and frosted, in this member ranges from 50 to 99%.

No sharp boundary has been recognized between the Joliette sandstone and

the overlying Laval rocks. It probably nowhere exceeds 50 feet in

thickness. The main part of the Laval Formation consists largely of fairly

coarsely crystalline limestone usually weathering buff in patches,

probably in response to high magnesia content. Fine-grained and very 8. coarse-grained types occur sparingly. Fossils are common throughout. At

Ste. Anne des Plaines it contains a small coral and bryozoan reef of the barrier type, but no indications of petroleum within it or in its flanking beds are known. It ranges in thickness from 250 feet to 500 feet, with a regional thinning toward the northeast although such thinning cannot be demonstrated within PR 514. The abundance of buff and brown weathering patches and beds indicates an incomplete dolomitization of the rock. This may have led to a porosity not apparent in surface outcrops but which might be of importance in depth. Especially is the porous and pervious Joliette sandstone of interest in providing a potential, though limited in volume, hydrocarbon reservoir.

BLACK RIVER GROUP: PAMELIA DOLOMITE, LOWVILLE LIMESTONE AND

LERAY LIMESTONE FORMATIONS. These formations, rarely more than 75 feet in aggregate thickness, are of little importance stratigraphically or economically. They are nowhere known to contain or to yield hydrocarbons.

TRENTON GROUP: DESCHAMBAULT, AND TETREAUVILLE LIMESTONE

FORMATIONS.

The Deschambault Limestone (Lower Trenton) is pretty regularly 70 to 100 feet thick here (Figure 4). It is a crystallized bio-fragmental rock made up in large part of crinoid plates and columnals worn and rounded by current action before final deposition. Recognizable fossils are common in certain beds. One of the most important features of this rock is the tendency toward vugginess. This occurs usually in coarse-grained beds up to 30 inches thick. Here and there residual hydrocarbon material lines the cavities. Of more importance is the fact that, save for the Tetreauville 90 100 o \ ~' ~~„~`--~..•-~.-.~-.~ ~ ~- ~00 _. , ~ \

Formation, this is the only formation known actually to contain liquid petroleum. At many localities, especially at St. Marc des Carrières

(40 miles southwest of Quebec City), where it is quarried, small drops of petroleum are liberated on a freshly broken surface, spreading out over an area of several square inches. A few drops of petroleum and a fair amount of albertite-like material were found in a vein in a core taken from this rock in the Neuville district. In the Louvicourt Metal No. 8

l'Assomption well (#151) petroleum was found yielding 3 to 4 gallons per day and lasting for a couple of days. Everywhere this rock has a strong odor

of petroleum when freshly broken open. At the Beaudry quarry, Joliette, a vein of albertite six inches across was reported during the early development

of the quarry, but of which no trace remains. This rock is therefore of

great interest as a source rock, and under favorable porosity and structural

conditions could yield satisfactory amounts of oil.

The Montreal Formation (Middle Trenton) consists of various types

of dark gray limestone, dense to fine-grained crystalline, thin to thick

bedded with partings and interbeds of shale up to several inches thick.

There is little regularity in bedding. No odor of petroleum has been

noticed in this rock nor is there any intergranularity favorable to hydro-

carbon storage. Rarely is there any dolomitization, and cavities are

restricted to the interiors of fossil shells which, however, never contain

residual hydrocarbons. It is therefore of little interest as either a

source rock or a reservoir rock. In thickness it ranges from 150 to 300

feet thick.

The Tetreauville Limestone (Upper Trenton), 400 to 500 feet thick,

consists largely of a dark bluish gray, dense, argillaceous limestone in 10. beds up to 6 inches alternating with beds of shale generally about one inch thick. Bedding is pronounced and even, allowing this rock to be dis- tinguished from other Trenton formations some distance away. Very rarely are there interbeds, up to 6 inches, or crystalline organic detritus.

Here and there both geographically and stratigraphically there are develop- ments of several tens, or even scores, of feet of limestone devoid of

obvious stratification. This is what was earlier called the Terrebonne

Formation, later degraded to Member status and now considered to be merely a facies development of the typical Tetreauville. The fauna of the latter

is large in number of species, but sparse in actual occurrence. Very little

difference can be found between the faunas of the original Tetreauville and

the Terrebonne rocks. It is supposed that the Tetreauville was deposited

in a quiet environment in which continued absence of muddy detritus allowed

carbonate deposition to take place, interrupted fairly regularly by con-

tributions of mud resulting in the shale partings and interbeds. The

Terrebonne facies on the other hand was probably the result of local and

temporary conditions of turbulence, destroying most or all traces of

regular bedding. Most of the Tetreauville limestone when freshly broken

open gives off a petroleum odor, and in a few places, notably along the

of Ile Jésus, droplets of liquid petroleum issue from small

( < 1/4") cavities. This formation therefore must be considered a potential

source rock, though nowhere does it possess adequate permeability or

porosity to qualify it as a reservoir rock.

THE UTICA SHALE. This consists wholly of dark gray to black

shale with a brownish streak, and gives off an odor of petroleum when

freshly broken. This last feature is more characteristic of the thicker

bedded dark gray part of the formation than of the thinner bedded black

f 11. shales. It is known to outcrop only at L'Epiphanie. Throughout, the rock is dense with no interbeds that might provide porosity and permeability.

Like the Tetreauville it must be considered a potential source rock but in itself could not function as a reservoir rock. In thickness it ranges from 300 to 400 feet.

THE LORRAINE SHALE. That part of this formation underlying the southeastern tip of PR 514 is a dark gray shale and siltstone, never black, and never with a petroleum odor. It is very thin-bedded, rarely very fossiliferous. Probably no more than 200 feet occur here, although where the complete section is known it is about 2,400 feet thick.

IGNEOUS ROCKS. Currently being quarried at L'Epiphanie, just

southwest of the village, is a basic sill, about 25 feet thick, and lying almost exactly along the Trenton-Utica contact in Achigan river a quarter

of a mile to the east. In L'Assomption Experimental Farm well (#46) igneous

rocks, presumably sills, occur within the lower Lorraine and upper Utica formations (50 feet in the former, 40 feet in the latter). In the Parent

well (# 93 ) an improbable thickness of 120 feet of igneous rock was logged

low down in the Trenton limestone. Neither in Louvicourt Metal No. 8

l'Assomption well (#151) log nor in the logs of any of the Oil Selections

wells is there mention of igneous rock. In Quebec Natural Gas No. 2

l'Epiphanie well (#142) igneous rock occurs between the basal Utica and

the overburden. It is likely that all these occurrences are related, and

if so then the sill staggers from one stratigraphie horizon to another and,

were its distribution underground better known, it might reveal itself as a

potential trap, holding hydrocarbons beneath it. 12.

STRUCTURE

REGIONAL SETTING. This area lies within the St. Lawrence Lowland

of Quebec (See Q.D.N.R. Map no. 1407, in pocket), and close to its western

border. The Lowland is floored by Upper Cambrian and Ordovician sedi-

mentary rocks which have been deformed into the elongated Chambly-

Fortierville syncline the axis of which is consistently east of the St.

Lawrence River until it crosses the latter close to Quebec City. The western

limb of the syncline, on which PR 514 is situated, is relatively simple in

structure and consists of beds dipping pretty uniformly toward the south-

east at angles of from 0 to 10°, regionally about 2°, affected here and

there with small irregularities of little regional significance. The

eastern limb, with which we are not here concerned, is characterized by a

complex structure including folds, isoclinal and overturned, thrusts, slices,

and autochthon-allochthon relationship and complications.

FAULTS. Northwest of the Lowland lies the vast area of Grenville

rocks of the Canadian Shield. The contact has been seen in but a few

localities, but enough is known to deduce that in places the Shield-Lowland

boundary is a normal stratigraphic overlap phenomenon, in others it is a fault contact. In fact, there is a series of en echelon faults (See

Q.D.N.R. Map 1407) helping to form this boundary, striking about N20°E to

N40°E; and with the downdrop, up to 1500 feet, always on the southeast side, thus making the Lowland a semi-graben. The northwestern part of this area lies a few miles from the trace of one of these faults, here named the Ste.

Julienne fault. Possibly the southwestern continuation of another of these en echelon faults, the Chicot fault, cuts across the eastern tip of the area.

No faults are actually exposed here, but their presence is 13. guaranteed by relationships in neighboring map-areas. Just northwest of

PR 514 the Ordovician rocks are in fault contact with Precambrian,

Beekmantown, and Chazy rocks along the Ste. Julienne fault. This strikes about N25"E, and the Ordovician rocks to the northwest strike N40°E to

N70"E and abut against the fault so that they are successively eliminated in stratigraphic order from north to south. Near Bissonnet the movement is of the order of 1000 feet, whereas a mile or so west of St. Lin, where

Chazy rocks are brought to lie against Chazy rocks, the movement is minimal.

On Q.D.N.R. Map 1407 the St. Jacques fault is shown as possibly continuing from the vicinity of St. Jacques southeastward to the northern boundary of this area. Whether or not this continuation can be justified, there is no evidence supporting the view that the St. Jacques fault actually occurs within the area of PR 514.

A second fault passing close to L'Epiphanie should also be eliminated. Since its proposal, and appearance on Q.D.N.R. Map 1407, the opening of a large quarry south of L'Epiphanie has shown that the Trenton-

Utica boundary is unbroken across the line of the supposed fault. Other details concerning this "fault" are given under Igneous Rocks (p. 11) and also below (p. 16).

Since the geological mapping of the Laurentides East and the

Derchères West areas were completed numerous wells have been put down within and adjacent to PR 514. Save for those drilled just outside and to the northeast of PR 514, at L'Assomption, none contributes to the identification and location of faults. Referring to Figure 2, in which the logs of four deep wells are given, there is a suggestion of some anomalous situation 14. between wells #103 and #31, but from such evidence it would be hazardous to postulate either a fault or a flexure there. Figure 5 gives the logs of most of the Oil Selections Wells. The logs of Oil Selections Nos. 1-4 are too short to indicate anything more than a southeasterly dip. The same appears to be true for Oil Selections Nos. 5-8 although there is there a record of a more flattened dip between Oil Selections Nos. 7 and

8 than between Oil Selections Nos. 5, 6, and 7. The larger group of wells, however, is more definite, and assuming a normally uniform dip toward the southeast it is obvious that Oil Selections Nos. 29 and 33 are out of step with the remainder. The locations of these wells were, for the purpose of drawing these diagrams, taken from Q.D.N.R. Map 1555. In order to arrive at more reliable conclusions, I plotted the location as given by the Q.D.N.R. in a mimeographed "WELL LIST WITH COORDINATES", of both the Oil Selections

Nos. 5-8 group and the Oil Selections Nos. 9-33 group as shown in Figures 6 and 7.

Taking the latter group first the positions of the wells were pro- jected along regional strike lines (Figure 6), upon an arbitrarily chosen base line perpendicular thereto. The intersections were then used to imply the stratigraphic order of the wells, and a correlation chart was drawn up using the top and bottom of the Utica Formation with results shown in Figure 7.

There, it is apparent that the normal down-dip inclination (i.e. toward the SE), which should be a reasonably smooth line, is broken in at least four places. The two northwestern breaks between Oil Selections Nos. 30 and 31, and Oil Selections Nos. 31 and 22, show displacements too great to be attributed to warping, and consequently faults are introduced there.

Between Oil Selections Nos. 24 and 18 the vertical drop of the top of the

Utica is 250 feet, necessitating a fault between those two wells. Similarly,

Between Oil

Selections Nos. 33 and 11 there may or may not be any faults, although the line connecting the tops of the Utica is not altogether in harmony with the regional dip, and with that connecting Oil Selections Nos. 22,

29, 20, 23, 9, and 24. Assuming that these faults are approximately parallel with the regional en echelon faults (e.g. Ste. Julienne) the pattern of faults appears as in Fig. 7.

This determination receives remarkable confirmation from the gravity map of the region (Figure 8) where the isogals show a strong deflection from a northwest-southeast trend to north-northeast--south- southwest direction.

A similar treatment of Oil Selections Nos. 5, 6, 7, and 8 shows discordances explicable only by faulting between Oil Selections Nos. 5 and

6, and between Oil Selections Nos. 6 and 7.

The gross result shows that, heading toward and doubtless crossing the northeast boundary of PR 514, there is a zone of NE-SW striking faults.

Between the stratigraphic horizons of Oil Selections No. 9 and No. 30

(see figures 6, 7) practically all of the Oil Selections gas showings, together with the oil show in Louvicourt Metal No. 8 l'Assomption (#151), are located.

None of these faults is exposed at the surface, nor has any been cut by the drill, consequently nothing is known of their nature in detail - whether they are clean cut surfaces, zones of fractures, brecciated zones,

tight or open, etc.

Several minor faults have been suggested as results of geophysical

and geochemical surveys.

FOLDS. No important folds are known in this area, or in ad-

• jacent parts of the Lowland to the northeast or southwest. This may

possibly be due to the paucity of outcrops. Small wrinkles are proposed to

explain aberrant dips and strikes, but none of these structures disturbs

the general northeasterly strikes and southeasterly dips of the beds.

IGNEOUS ROCK BODY PROBLEM. If one draws a line from L'Epiphanie

village southeastward to the junction of routes 48A and 3, wells to the

southwest (Q.D.N.R. #142, #, #46) show basic igneous rock, whereas those

to the northeast and river outcrops at L'Epiphanie show none. That this is

not a vagary due to limited amount of igneous rock is shown by an outcropping

sill at L'Epiphanie 25 feet thick, 120 feet of igneous rock in the Parent

Well (Q.D.N.R. # C93,), and 40 feet in L'Assomption Experimental Farm Well

(Q.D.N.R. #46) . In Quonto-International No. 1 Mascouche (Q .D .N .R . #58)

there were three horizons of basic sills, the lowest from 1407 to 1414 feet

with a thickness of 64'; it is not known whether this last occurrence is

connected with the L'Epiphanie-L'Assomption body. There is no certainty of

the spatial distribution of this igneous rock. At L'Epiphanie it is

obviously a sill; at the Experimental Farm Well (Q.D.N.R. #46) it is probably

a sill; at the Parent well (Q.D.N.R. #3)) its thickness is reported to be

120 feet which, if correct, would probably rule out the sill nature there,

and might indicate an intersection of a dike slightly off the vertical.

Whether of not it has, or may have, a bearing on the finding of gas or oil.

17. its termination along the line suggested above is remarkable. One would expect the surface limit of a sill, intruded parallel to the bedding, to

be a line following the strike of the beds, whereas the northeastern limit

of this body seems to be at right angles to the strike of the bedding. Of

this there is probable confirmation in the Gravity Map (Figure 8), where an

area of low gravity relief stretches south-southwest from L'Epiphanie and

L'Assomption, but the isogals show a marked deflection along the line in-

dicating the northern limit of the "sill". The "flat" area referred to above

may either represent a ridge in the Precambrian basement, a terrace

structure, as discussed above, or it may be merely a reflection of the

presence of an abnormally large and widespread body of igneous rock.

KNOWN OCCURRENCES

PETROLEUM No occurrences of liquid petroleum are known within the

limits of PR 514. However, oil was encountered during the drilling of

Louvicourt Metal No. 8 l'Assomption well (#151) in 1966, between 1332' and

1340' below the surface. This horizon, not identified stratigraphically

in the report, should be close to the Montreal-Deschambault interface.

Production was estimated at 2 bbls/day, and diminished after a few days to

.3 bbl/day. The oil is reported to have been very light Pennsylvania type.

Oil is recorded in Q.D.N.R. S-75 from Oil Selections 6 (#88), 9 (#91), 30

(#99) and 31 (#101), and also from Louvicourt No. 7 l'Assomption (#145), but

because no amounts are given the occurrences were probably inconsequential.

NATURAL GAS As is the general custom in rural areas in drilling

for water, the operations stop at the drift-bedrock interface. This is

well shown in the accompanying table (p. 18). Where a well stopped before 18.

TABLE 1. GAS WELLS IN THE CABANE RONDE AREA.

A period following the "depth to rock" figure signifies that drilling

stopped at the drift-rock interface. A plus sign indicates that the

drilling stopped within the drift.

There is no evidence from any of the sections of drift that decomposition therein would produce gas and hence the assumption is that it is rock gas that has seeped up into the drift. Drift gas has proved commercially ex- ploitable at Pointe du Lac, where more than a dozen wells 200 feet or so deep and entirely within overburden have measured production rates of from one to five million cubic feet per day, and at present three of these wells are tied in to a pipe-line to Three Rivers where the gas services industrial plants. Drift gas coming from isolated pockets may issue violently at first, but after a few days or even weeks, gradually peters out. Those wells with appreciable production, as at Pointe du Lac, which remain con- stant over a period of years are certainly fed by a reservoir in the rock, and this reservoir should be the goal of the drillers.

Very few occurrences of natural gas in water wells have been noted within the PR 514 limits and almost all are in the L'Assomption-

L'Epiphanie area. However, as with petroleum, there are encouraging records from nearby regions. North-northeast of L'Assomption, from two to four miles along the road paralleling Pointe du Jour brook, there are several natural gas occurrences, some of which were related to water wells and others to holes drilled by Oil Selections Ltd. in their search for oil or gas. There are unfortunately few technical recordings of the amount of gas available, but Oil Selections 29 (#99) yielded, at 1012', 185 Mcf/day, shut-in pressure 450 psi; and Oil Selections 30 (#100), at 1017', 32 Mcf/day, shut-in pressure 320 psi. Both of these horizons are about 300' below the top of the Trenton. In addition to the above, unmeasured horizons were encountered at Quonto-International No. 1 Mascouche well (#58), L'Assomption 20.

Experimental Farm well (#46) , Oil Selections 8 (#90) , 9 (#91) , 11 (#92) ,

20 (#94), 21 (#95), 22 (#96), 23 (#97), 31 (#101), and 32 (#102). Also five miles northeast of the last two, the Mohr No. 1 well (#80) yielded gas at seven horizons, all in the Trenton limestone.

Secondly, from 3 miles to 7 miles south-southwest of L'Epiphanie, in the Cabane Ronde area nearly 40 occurrences of natural gas are known, mostly from water wells, but a few from wells drilled specifically for oil or gas (See Table 1, p 18). An average of two analyses of gas from this region gave the following (see Appendix B, Nos. I and II):

Methane 86.5% CO2 1.9 Oxygen 1.6 Nitrogen 10.0 Helium tr.

POSSIBILITY OF FINDING COMMERCIAL QUANTITIES

STRATIGRAPHIC TRAPS. There are five possibly porous horizons which should

be explored as stratigraphie reservoirs. 1) Basal Potsdam: although the

lower part of the Potsdam has little if any porosity or permeability the

basal few score, or in places hundreds, of feet are conglomeratic, and are

known here and there to rest upon a brecciated zone made up of fragments of

the Precambrian basement as well as pebbles and scraps of sandstone - in

other words, what may be called a granite wash; 2) the upper Potsdam sand-

stone already referred to; 3) the basal Chazy sandstone; 4) porous horizons

in the Deschambault limestone; and 5) in the extreme eastern part of the

area sandstone lenses within the Lower Lorraine. None of these stratigraphie

horizons has a great vertical component, but if a structural trap could be

demonstrated covering a large enough area a sizeable oil or gas field might

result. 21.

The only unconformity known in this area lies between the

Trenton and Utica rocks. The Lower and Middle Utica are missing, so that

the Upper Utica lies upon the Trenton. Nowhere is there any recognizable

angular discordance between the two formations, but a difference of a

fraction of a degree could well be responsible for a trap of fair sized

proportions. Immediately below this interface lies the Upper Trenton con-

sisting of dense limestone and thin shale beds - not an encouraging reser-

voir combination, although the 300 feet more or less of Utica shale should

provide an effective impermeable cover.

In an area of limited extent, such as PR 514, few facies

developments can be recognized. This is also true if the surrounding map-

areas be taken into account. No facies are known in the Potsdam and the

Beekmantown Groups. Within the Chazy Group there are small reefal develop-

ments, the nearest one being at Ste. Anne des Plaines where a barrier-type

reef 700 feet long and probably no more than 5 feet high is bordered by

inclined flanking beds of crystallized biofragmental limestone. The Black

River Group, as seen in well cores differs in no way from its equivalents

to the northeast and the southwest. There is no facies development within

the Lower Trenton, but the lowest formations,the Mile End at Montreal, the

Ouareau locally and to the northeast, are interpreted as having been

deposited independently in separate shallow basins tectonically developed on

the Black River beds. The Lower Trenton Deschambault and the Middle Trenton

Montreal formations are no different from their equivalents along the

regional strike. Down dip, i.e. in the direction of the axis of the

Chambly-Fortierville syncline, the Middle Trenton is replaced by black

shale, but this change is removed from PR 514 by at least a score of miles.

Within the regularly bedded Upper Trenton Tetreauville Formation there may 22. be one or more developments of unstratified limestone, known as the

Terrebonne beds, which are a response to sea-floor turbulence and not to differences in supply or nature of sediment. No facies changes in the

Utica or Lorraine beds are known.

POROSITY AND PERMEABILITY. First it should be noted that very few strati- graphic horizons show intergranular porosity here. Possible granite wash at the base of the Potsdam; the Upper Potsdam sandstone; the basal Chazy sandstone; and the Deschambault limestone are horizons with possibilities, though little is known of their vertical dimensions. Nevertheless they should be tested in all wells drilled here. As far as is known there are no records of porosity or permeability of rocks occurring within or adjacent to PR 514.

Fracture Porosity is the most likely factor in the accumulation of hydrocarbons in PR 514. A few miles northeast of L'Assomption findings of appreciable amounts of oil and gas have been recorded in the logs of

Oil Selections wells and of Louvicourt Metal well No. 8 l'Assomption. In all these cases there is a definite spatial relation between the occurrences of gas and faults. Although amounts of gas and oil have so far been found definitely short of commercial acceptability, it cannot be said that this possibility has been adequately prospected. Hydrocarbons, rising westward up-dip from the central part of the Lowland basin would sooner or later come up against one or more of the en echelon faults. Where such a fault is open the fugitive hydrocarbon would escape to the air. In such places where the fault were tight either as a single plane surface or a series of parallel plane fractures, an accumulation of oil or gas would result. This is 23. probably what has happened just northeast of L'Assomption, and the ex- tension of this fault zone to the southwest into PR 514 should be intensively investigated.

STRUCTURAL TRAPS None involving folding of the sedimentary sequence such as terrace structure within the monoclinal sedimentary sequence, closed elongated anticlinal structures, domes or basins have yet been demonstrated from knowledge gained from outcrops, and geophysical or geo- chemical surveys must be relied upon to locate such structures. Three situations resulting from geophysical surveys have come to light.

First: an isopach map of the Deschambault Formation (Lower Trenton)

shows that there is a shallow basinal structure (Figure 4) in part of the

western half of PR 514 involving a closure of at the most 20 feet.

Second: referring to the Total Gravity Map (Figure 8) there is

a significant flattening of the dip of the isogals going southeastward from

the northwestern part of this map. This could indicate a terrace structure

in the sedimentary series; or possibly it could be related to the igneous

rock body outcropping at L'Epiphanie and found in wells at L'Assomption; or

it could be a reflection of an irregularity of the Precambrian surface.

Until further geophysical surveys (preferably seismic) add more information

this anomaly will remain of problematic value.

Third: in a report on a radiometric survey over the territory

northeast of PR 514 (See Que. Dept. Nat. Res. Archives, GM 16580,. July 24,

1964) Hans Lundberg noted an important anomaly extending along Rivière du

Pointe du Jour, and continuing south-southwestward for 3 miles along the

Assomption river following a line of poor but definite anomalies. The 24. first of these locations has been extensively drilled by Oil Selections

(Figures 5, 6, 7) and a sub-commercial production of gas was obtained, in the opinion of the writer from a fracture zone accompanying the supposed southwestern extension of the Chicot fault. The second location lies within the limits of PR 514 and should be thoroughly tested.

In the Pointe du Jour area, oil has been reported from Oil Selections nos. 9 (#91), 30 (#100), and 31 (#101) at horizons singularly uniformly below the top of the Trenton -- 198'-221', 189'-209', and 190'-240' respectively, all are within the Tetreauville Formation. Although this horizon should be carefully inspected, the dense limestone with shale interbeds would scarcely

have sufficient porosity and permeability to create reservoir conditions.

The significant oil find from Louvicourt Metal No. 8 l'Assomption (#151),

came at 602'-610' below the top of the Trenton and 153'-161' above the base,

probably low down in the Montreal Formation. In Oil Selections No. 6 (#88)

a trace of oil was found 360' below the top of the Trenton and 417' above the

base, certainly within the Tetreauville Formation.

A tabulation of gas occurrences from wells listed on page 4 (in-

cluding also the Mohr No. 1 well (#80) shows that there are nearly three

times as many horizons in the Upper Trenton that have yielded gas than all

others combined. This may be because the Upper Trenton is the highest

stratigraphically capable of maintaining open fractures. Both Utica and

Lorraine shales have a high percentage of clay minerals which may have been

f 24a.

responsible for their inability to keep fractures open. Hence, because the

dense Utica shale is an ideal cap rock, hydrocarbons migrating up-dip

westward and rising through a fracture zone adjacent to, say, the Chicot

fault, would be trapped beneath the Utica shale. Perfect or imperfect

sealing by the cap rock would contribute to the spotty occurrence of gas

along these fault lines. 25.

RECOMMENDATIONS

A gravity survey covering the whole area is recommended to out-

line, if present, any original structure of subsequent deformation of the

sedimentary rocks resulting from irregularities of the Precambrian basement.

Elsewhere in the Lowland gravity surveys have proved very useful in

locating major faults, and because in the opinion of the writer fracture

zones along faults are likely to prove more successful in holding trapped

hydrocarbons, I recommend a complete coverage by a detailed gravity survey.

For more accurate determinations seismic surveys should be relied

upon. It should be a matter of company policy as to whether the entire area

be surveyed seismically, or whether certain parts of the area be subjected

to minute scrutiny.

A magnetic survey might well be misleading because of the possi-

bility of the presence of magnetic bodies of Precambrian rock in the base-

ment. If a magnetic survey should be made and should turn up a magnetic

high the structure should be drilled at once to determine the reason for its

presence.

The best results would probably be obtained from the use of the

recently developed high resolution air-borne magnetic procedure. Theoretically,

such a survey could be conducted with 1/1000 gamma interval, but in practice

20/ or 50/1000 gammas have proved practical and remarkably successful. The

exceptionally high cost, several times that of the standard air-borne mag-

netic survey, is well repaid by a more detailed map requiring very little

extrapolation, and with contour lines more adequately controlled and more 26,

closely spaced. This method seems to be particularly well adapted to

the conditions obtaining within the limits of PR 514.

No matter what geophysical surveys be depended upon I suggest

that particular attention be paid to that part of the area lying between

L'Epiphanie and L'Assomption, for it is here that one should find the

continuation of the faults shown in figure 6. A very careful examination

of this restricted area and extensive drilling should be rewarding.

Drilling is not recommended during the first four months of the

year. Side roads are not always adequately snow-ploughed to allow the

passage of drilling rigs or trucks bringing materials and supplies. This

applies more acutely to access roads, if any, to the drilling site.

Compensation to the landowner can be negotiated privately, or in case of

a disagreement the dispute may be submitted to a government arbitrator. 27. A22E2; LIX A
