Mineral Appraisal of Lands Comprising Townships 14, 15 , 16 and 17 South, Ranges 14, 15 and 16 East, SLM

Roan Plateau - Desolation Canyon Area , Carbon and Emery Counties, Utah

by R. E. Cohenour

This is an appraisal of the coal, oil and gas, oil shale, and bituminous sandstone potential of lands in the Roan Plate3u between the Book Cliffs on the west and the Desolation Canyon portion of the Green River on the east. The area comprises Townships 14 I 15,16 and 17 South, Ranges 14,15 and 16 East I Salt Lake Base and Meridian, a total of 12 townships.

Based on this study 11,040 acres of land potentially important for tar sand and coal development are recommended for lieu land acquisition. It is suspected that approximately 8,800 acres of the recommended area are available for transfer.

REGIONAL GEOGRAPHY

The western tier of tov.nships! namely T., 14: 15! 16 and 17 SOl R. 14 E. , are wholly or partially accessible from U .S. Highway 50-6 which approximately parallels the Book Cliffs along the western edge of the area (Fig 1). State Highway 123 and a branch line of the Denver and Rio Grande Railroad provide access to Dragerton, Utah in T. 15 S., R. 13 Eo I near the northwest corner of the area. The greater portion of the area is inaccessible I representing some of the most rugged terrain in Utah, total relief being 5 ,925 feet. The hig hes t promin,tnce is Bruin Point at 10,285 feet and the lowest is on the Green River at approximately 4,360 feet above sea levelo Elevations in excess of 8,000 feet are common. The high a::itudes attribute tc the ~ eve~y of weather which pre­ vails throughout most of the year over most of th.e are3 0

The north-south trend of the Book Cliffs marks the westernmost extention of Significant coal bearing sandstones (the coal measures) in this area. The coal measures are Cretaceous in age ar..d are overlain by the Wasatch Formation of Tertiary age which in turn is overlain by the Green River Formation. The upper Wasatch and Green R.iver Formations form a second prominance known as the which mark the beginning of the Roan Plateau 0

MINERAL POTENTIAL

The twelve townships comprising the main portion of this appraisal all contain res erves of coal and the northern third of the T 0 14 S . J R 0 14 E., con­ tains cropping of bituminous tar sands (see Fig 2) 0 The oil and gas potential of the block cannot be adequately appraised because of the scarcity of drilling; only 2 wells (dry) have been drilled in the area (Figs. 1 and :3). Oil shale, though present in the northeastern portion of the area; has questionable potential based on two measured section.s which indicated marginal potential.

Oil and Gas Potential: Two horizons for possible oil and gas production underlie most of the area; they are the Tertiary Wasatch - Green River transition zone and the Cretaceous zones.

The shallowest zone is the Wasatch - Green River transition zone which is from 9 to 3,000 feet from the surface. The Sunnyside tar sands which extend into

Sections 3 14,9 I 10 and 15, T. 14 S. I R. 14 E 0 I repres ent large remnants of an oil accumulation near this zone. Surficial trend the Peter1s Point - Jackis Canyon structural axis (see Fig. 3) and several dry hcles situated in line between the tar sands and the Peter's Point field preclude any direct proj ection or connection of the tar sand trend to this axis. The Sunnyside tar sand is treated as a separate potential unit and projection of its petroleum possibilities dre restricted to an area within a few miles of tre outcrop (see Fig 0 1;r Bituminous Sandstone Potential and Recommenda tions D).

known trends or geologic projections or 'oil structures u however u there are numerous small oil seeps and shows along the zone ir:. outcrops above the Book Cliffs. The scarcity of drilling indicates that the Wasatch-Green River zone in the appraised area has not been adequately tested and that its oil and gas potential cannot be est.imated as being either favorable or unfavorable.

The"Cretaceous zone likewise has not been tested and early condemnation is not warrented.

The lack of favorable structures (anticlines) wi~hin this section of the Book Cliffs and Roan Plateau does Lot enl:ance the oil possibilities of the area; by the same token the probability for stratigraphic trap-type accumulations of petroleum cannot be ignored. There is the pes sibility that the edge of the buried Uncompahgre Uplift extends into the area and the possibilities for petroleum along the flanks of this trend rna y be good; here again drilling is no: of sufficient density or depth to properly assess this assurr..ption.

The better part of the occurrence is accessible by road and is 5 miles due

2. The deposits crop out along the southwest facing the escarpment of the Book Cliffs at elevations between 9 J 000 and 10 1 000 feet above sea level.

3. The beds of bituminous sandstone range from 10 to 350 feet in thick­ ness in a zone about 1,000 feet thick in the upper part of the Wasatch and the lower part of the Green River Formations (Green River - Wasatch Transition zone) .

The zone extends for approximately 9 miles alon.g the cliffs 0

4. The deposits have been worked since 1892 and as of 1945 some· 335,000 tons of bituminous sandstone has been produced 0

Likewise v it tapered to zero to left ar~d right of main thickness.

9 0 ConsideraEon of this and other bitumen J oit and asphalt occurrences in the area one may reasonably assume that the U oS 0 Geological Survey is much too conservative because~

A 0 The sand zone of the Wasatch-Green R.~ver transitional facies here at Sunnyside is much like that situated s~bsurface in the Redwash-Wonsits oil fields.

B. Fracture porosity in the Green River oil shales in t.r~e Brennan Bottoms field and the presence of gilsor:ite and other mineral hydrocarbons in the Uinta Basin and at Soldier Summit areas indicate that the Green River on shale section is capable of giving up low viscosity oil and bitumens.

C. The overburden northeasterly from the Sunnyside bituminous sandstones increases substantially toward the cen":er of the lJinta Basin g therefore 8 enhancing the possibility that the pore space of the sands of the Wasatch-Green

River zone be filled with oil or bitumen 0 Page Five Report #11 December 6, 1963

D. The northeasterly continuity of the bituminous sandstone is fairly well substantiated by the presence of oil and gas from the Jack's Canyon and Peter1s Point oil and gas fields some 13 miles northeasterly from the Sunnyside outcrop. Production of these fields is from the Green· River­ Wasatch transition zone which is the same geologic environment as that of the Sunnyside bituminous occurrences.

Four wells in T. 12·S., R 0 16·E ~, are representative of thepetroliferous trend of the Green River-Wasatch transition zone, they are:

EI Paso Nato Gas #4-X Jacks Canyon; in Sec ~ 33; for 48 BOPD and 1.35 million CFGPD

El Paso Nat 0 Gas #5 Jacks Canyon; in Sec. 32; for 20 BOPD shut in

Hyland Oil #7 "Jacks Canyon; in Sec. 33; for 155 BOPD

EI PasQ Nat Gas *2 Peters_ POint; in Sec 0 36; for 2 . 12 million CFGPD

E. The tar or bitumen represented as interstitial material at Sunnyside may not be a representative of an oil seal plugging petroleum mig­ ratory route but may be likened to·a sponge or pore space which is presently accomodating petroleum and bitumen that is being squeezed from the overlyirig oil shales.. If such a process is active then strand-line or deltaic facies of the Wasatch-Green River transition would. be charged with bitumen or oil whereever porosity and permeability was adequate. _ This concept affects the reserve picture in that more drastic or far-reaching proj ections of the bituminous sandstone from the outcrop are warranted.

10. Reserve estimates of the bituminous sandstone deposits near Sunny­ side, Utah are therefore based on Ball's figures which are:

1 ,700 strippable acres.

749.93 million tons of bituminous sandstone at 70% recovery.

2.6 to 13.5% bitumen by weight (9% bitumen is average).

9% bitumen·is equal to 20 gallons per ton of bituminous sandstone. Page Six Report ill December 9 I 1963

Bituminous Coal Potential: There are as many as 6 workable (mineable) coal beds in the Mesaverde outcrops along the Book Cliffs in the area. Coal thicknesses

range from about 3 feet to more than 10 feet 0 The coal bearing strata clip north

and northeastward from 3 to 14 degrees 0 All deposits are more or less broadly lent­ icular and much thinning and thickening .of the coal is evident. All of the coals are of bituminous rank and a fair proportion of the reserves constitute coking coal.

The Coal Measures comprise between 1,400 and 2, SOO feet of strata com­ posed principaUy of sandstone, silts and shale and a minor quantity of coal. (Coal measures refers to a sequence of sediments that were deposited in an en­ vironment which was suitable for the formation of coals and does not imply that all strata are coaly or contain workeable coal beds 0) 3 The coal reserves shown on Figure Z" are all classed as I inferred I reserves. It is acknowledged that a band-like area extending along the Book Cliffs for a depth or linear distance of three miles into the cliffs may be classed as an area of in­ dicated reserves but because further breakdown would be cumbersome the I indicated I and I inferred I reserves are lumped together. Each township or partial township with­ in the area of coal reserves Figure~) is marked with figures which designate the estimated mineable coal for each square mile within the particular township. (Data from U.S.G.S. Bulls. 793 and 852) .Coal reserves were extended to the limits of the outlined area on the basis of coal occurrances in many of the drill cuttings from deep oil wells northwestward in the Uinta Basin, in particular the Cities Service #1 Peters Point well in T. 13 S., R. 16 E., in the northeast corner of the reserves area. The mineable coal reserve estimates range from 6 to 16 million tons per section with­ in the apprais ed area.

A major factor in present day coal mining operations is the amount of oV'e'l'burcien or depth to coal; deeper coal z ones must be more persistent and thicker than shallow zones to warrent the expense of a deep mine shaft capable of handling a large tonnage, because of this the approximate depths to the top of the coal measures are noted at the corners and at the centers of the townships considered. The lenticular characteristics of coal cannot be predicted over broad areas and the actual depths to mineable coal maybe from a few to as much as 2, 500 feet deeper than the figures indicate. Improved techniques of coal exploitation and utilization as well as future demands and the paucity of easily accessible coals will necessitate the mining of these deeper coals; however, it is impos sible to predict the time when th~y would become economic.

The State has previously applied for a considerable area of coal lands in T. 13 S., R. 14 E., where in mineable inferred coal res erves are es tima ted to be 1 6 million tons per square mile. Also shown on Figure 2 are the remainder (check status) of the State l s holdings in the appraised area. The state l s title to coal lands within Page Seven Report #11 December 9, 1963

this bituminous province seems well repres ented and the expenditure of 'mineral' base for additional coal lands wherein coal would be the only valuable mineral product is not warrented (See Recommendations) .

Oil Shale Potential: The outcrop pattern of the Green River Formation(Figure

3j encompasses most of the northeast section of the appraised area c The only oil shale measurement within the area is an estimate of 15 feet that carry 15 gallons of oil per ton,l Sec. 27, T. 14 S ., R. 16 E" (from Synthetic Liquid Fuel Potential

of Utah - Lord, Bacon, and Davis, Dec 0 I 1961, Exhibit 18). Similar estimates of 15 feet of 15 gallon shale are from localities 10 to 14 miles north of the area (See Figure 3). The scar city of measured sections of oil shale does not imply that better

oil shales are not present in the area I but suggests that possibilities for finding good to excellent (high yield shales) ate poor. Today's standard minimum oil shale reserve which is considered economic, is 25 feet of s hale which contains 25 gallons of oil per ton. A very rough preliminary estimate of the shale-oil reserves would be 5 feet of 5 gallon rock or about 55 million gallons per square mile.

COMPARATIVE DATA ON INSTALLATIONS REQUIRING LARGE TONNAGES OF COAL AND OIL SHALE AS BASIC RAW MATERIALS

Future large uses of coal and oil shale will be £Or, (1) the generation of steam-electric power near the available coal, (2) pipeline transportation of coal slurry to remote and out-of-state locals for basic industries and steam-electric power, (3) manufacture of petroleum pr~ducts by the hydrogenation of coal, and (4) recovery of petroleum products by retor;ng and mild hydrogenation of oil shales.

Coal Fired-Steam Power Installation vs. Pipeline Transport of Coal

Basic considerations related to a coal-fired steam-electric power installa­ tion to the pipeline transportation of coal (from or at communication with Dr. George R. Hill, Head of Department, Fuels Engineering, College of Mines and Mineral In­ dustries, University of Utah) .

1. A steam electric plant similar to the Utah Power and Light Company's Castlegate power plant but scaled up to a million ton coal requirement per year would use 19.3 acre-feet of water per day or 7 ,045 acre-feet per year. This water

is used to operate condensers and is lost to the atmosphere 0 Condensers may be cooled by forced air utilizing electric powered blowers, but this results in a 20 per­ cent consumption of the power generated which in turn increases the generation

costs by approximately 20 percent 0 Steam-electric plants using near 2 million tons of coal per year are presently in operation in the United States.

2. Transportation of coal by pipeline at the rate of one million tons per year would require 1.4 acre-feet per day or 511 acre-feet per year. Consolidation Coal Company estimates that pipeline transportation of 6 million tons of coal per year would require 2,968 acre-feet of water. Thus, the water required for deliver­ ing one million tons would be 495 acre-feet per year (2,968 + 6). Page Eight Report 4f11 December 9, 1963

3. Comparing 'water-coal' relationship for local steam power generation with pipeline transportation of coal we have:

A. A million tons of coal mined and 7,045 acre-feet of water lost in power generation. B. A million tons of coal mined and 495 acre-feet of water lost in transportation. C. If 7,045 acre-feet of water is expended in transporting coal by pipeline,' then 1402 million tons of coal could be mined 0 D. Economic considerations pertinent to the State would be the comparison of revenues and taxes derived from an electric power installation, its distribution network and its subsidiary (1 million ton capacity) coal mine with the coal mines, installation and pipeline network capable of transporting 14.2 million tons of coal per year. Water requdrements are identical and any taxes or revenues derived from water would be the same. E. Utah has an abundance of doal and is not too well endowed with surplus water for future use, therefore, it would seem that the prudent course would be to de~elope all resources which would require the least expenditure of water. Some basic industries such as power stations, steel mills, and so forth, though de­ sireable from the taxation standpoint are esentially 'water hogs.' It would seem that industries such as shale oil, and others which have low water requirements should be encouraged.

Shale Oil Retort Plant v. s. Coal Hydrogenation Plant

A comparison of a shale oil installation with a coal hydrogenation plant both capable of producing 10,000 barrels (42 gallon) of petroleum products per day is as follows: (from U.S. Bureau of Mines 1949-50 data and 1951 report on the Synthetic Liquid Fuel Potential of Utah by Lord, Bacon and Davis) .

Shale Oil Coal Hydrogenation

Raw material 14, 035 tons of s hale/da y 4 I 300 tons of coal/day (containing 30 gallons/ton) (averaging 98 billion Btu)

Water requirements (A) 2.8 acre-feet/day 23.4 acre-feet/day

Personnel 278 1,175

Capital Investment $64,273,000 $133,473,000

Operating costs $3. 73 per barrel $5093 per barrel

Dollars required for each percent of gros s return on Capital Investment $ O. 199 per barrel Page Nine Report #11 December 9, 1963 Shale Oil Coal Hydrogenation

Value per barrel (B) $ 5 • 10 $ 5 0 12

Waste-Foul water (C) 40 to 70 thousand 50 thousand gallons/day gallons/day

Waste-Solid (D) 10,000 tons spent 286 to 740 tons ash/day shale/day

Footnotes: A. The excess water requirement of the coal hydrogenation process over the shale-oil process is because the hydrogen used is mainly

derived from the water 0

B. Shale oil yields mainly jet fuel and diesel oil whereas, hydrogenation of coal yields mainly gasoline with considerable propane and butane.

C. Costs for treatment and purification and disposal of foul waters are included in capital investment and operating costs.

D. Spent s hale from shale oil proces s would require a dis­ posal area of approximately 230 acres, based on a 40 year plant life. One ton of spent shale per barrel of oil is average for a 30 gallon per ton oil shale. Spent shale has a volume of 1 1/3 cubic yards per ton.

Much of the foregoing information is changeable in light of present develop­ ments and improved technology, however, three factors though changeable will remain essentially the same, they are: (1) in an oil shale retort type operation (above ground distillation) there must always be spoil or waste pile of spent shale, (2) a coal hydrogenation plant will always require an expenditure of about 8 times as much water as shale oil retort operation, (3) shale oil raw feed will amount to 3 1/2 times the tonnage requirements of a comparable coal hydrogenation plant.

RECOMMENDATIONS

A. No lands within or contiguous with the appraised area are recommended

for their coal content or coal potential for the following reasons 0

1. The State has title to and has pending applications on sufficient coal acreage to protect its future in the Book Cliffs area.

2. Utah does not contain inexhaustible surpluses of water for the support of basic coal-using industries 0 (See preceding section.) The presently accessible Page Ten Report #11 December 10, 1963 coal reserves privately held and leased by federal and state government are of sufficient size to seriously effect the present water surpluses within the region if these coals were utilized in or near the area for expanded electric power generation, hydrogenation or pipeline transport 0

3. Pipeline tr ansport of coal to be used in basic industi'res outside of the State is by far the most economic from the standpoint of conservation of water. Coals clos er to the most promis ing potential power market, the Nevada -California territory, should be acquired in preference to those farther removed from this market.

In other words the strategic location of coals in the Kolob I Kanab I and Kaiparowits fields makes them mere desirable for acquisi~ion than those of the Book Cliffs region, providing sufficient water can be developed for either pipeline transport of coal or for local steam-electric power plants. (Note: There may be an outSide chance that in the future Utah coal p!"oducers may be able to transport a small portion of Calif­ ornia's River water allocation to California in a pipeline products slurry.)

B. No lands are Singularly recommended for their oil shale content since the few measurements available indicate that the shales are below minimum requirements of 2S feet of 25 gallons of shale oil per ten. Vast areas of higher grade strippable or easily mined shales are still available for aquisition within the general reg ion.

C. None of the lands are singularly recommended for their oil and gas possibilities. However, there are many s.,r.1r.ll and a few large oil seeps along the Roan Cliffs which indicate that there are chances for commercial oil pools but the lack of surface structures and subsurfaces stratigraphic data prohibits the location of specific target areas wherein commercial oil pools could be expected. (See bituminous sandstone recommendation) .

D. Bituminous sandstones of the Sunnyside tar seeps crop out in Sections 3,4,9,10, and 15, T. 14 S., R. 14 E., within the appraised area and in Sections 18,19,20,28,29,32 and 33, T. 13 S., R. 14 E., and Sections 13,14,15,23,24,25, 26 and 35, T. 13 S., R. 13 E., which are contiguous with the apprais ed area. Available acreage in and near the tar seeps are recommended for aquisition and expend'­ iture of mineral base is warrented but only if the tota~ mineral estate is included in lands aquired. (i. e., OIl, tar, all minerals etc.)

The Sunnyside tar seeps are recommended fo:" the following reasons:

1. Conservatively, there are 1,700 acres comprising the minEable (by open pit methods) reserves of 749,930,000 tons (based on a 70% recovery) of tar sands containing 357,110,000 barrels of oil (bitumen). Productive beds dip from 3 to 10 degrees norhteasterly into the Roan Cliffs and average 30 feet in thicknes s; the overburden thickness averages 25 feet. The oil (bitumen) content averages 20 gallons per ton.

2. The area of the tar seep and the recommended lands is underlain by coals which are estimated to represent reserves which range from 6 .. 1 to 12.9 million tons per square mile (see figure 2). Page Eleven Report #11 December 10, 1963

3. The tar sand may be a plug or tar seal up dip from a significant oil pool thereby allowing for the proj ection of an oil and gas potential for some distance northeast (down dip from the seep). Therefore lands are recommended

for a distance of two miles from the seep (see figure 3) 0

4. Though not impressive oil shales are present and possibly represent long range low grade shale oil reserves which enhance the mineral estate.

Descriptions of the lands recommended are as follows: T. 13 S., R. 14 E., SLM S ubdi vis ion Acres Sec. 7 All 640 Sec. 8 All 640 Sec. 9 SW 1/4 160 Sec.

E. No coal lands are recommended near the Green River because of low reserve estimates in the areas where coals may be attained within 2 ,500 feet of the surface. Page Twelve Report #11 December 10, 1963

A preliminary canvass of State records indicates that possibly 8,800 acres within the recommended area of 11 ,040 acres are available for aquisition.
