These strata were deposited in a peripheral foreland basin that formed as the southernmost terrane of Tibet was sutured onto southern Asia.

RESERVOIR ISSUE 3 • MARCH 2008 25 Reservoir Engineering for Geologists Part 5B – Material Balance for Oil Reservoirs | by Ray Mireault P. Eng., Chris Kupchenko E.I.T, and Lisa Dean P. Geol., Fekete Associates Inc..

Material balance calculations for oil reservoirs are more complex than for gas reservoirs. They must account for the reservoir volumes of the produced fluids and the effect of pressure depletion on the oil volume remaining in the reservoir. They must account for the formation, expansion, and production of solution gas. The calculations must also account for the expansion of the reservoir rock and formation water, since they have similar compressibility as oil. As noted in last month’s article, typical compressibility ranges are:

• Rock: 0.2 to 1.5x10-6 kPa-1 • Gas: 10-3 to 10-5 kPa-1 (Varies significantly with reservoir pressure.) • Water: 0.2 to 0.6x10-6 kPa-1 • Oil: 0.4 to 3x10-6 kPa-1

Nonetheless, in theory, material balance calculations can provide an independent estimate for the original oil-in-place for a solution gas drive reservoir with sufficient production history.

Havlena and Odeh (1963) developed a Figure 1.

The Havlena-Odeh plot cannot however, identify the reason for pressure support or the pressure deficit. Potential reasons for pressure support include:

• An unaccounted-for water injection/ disposal scheme. • Flow from a deeper interval via a fault or across a fault from an adjacent reservoir compartment. Note that the fluid can be any combination of oil, gas, and water. • “U tube” displacement of the producing reservoir’s water leg by a connected reservoir. The connected reservoir is usually gas-bearing and may be undiscovered. • Expansion of water. Due to the limited Figure 2. Multi-Well Gas Reservoir P/Z Plot. compressibility of water (0.2 to 0.6x10-6 kPa-1) the water volume must be at least 10 times the reservoir oil volume for water expansion to provide pressure support. Thus the Cooking Lake aquifer underlying Alberta D-3 oil pools has the potential but water legs in clastic reservoirs are too small.

Potential reasons for a pressure deficit or downward curvature include:

• Later time interference from unaccounted- for producing wells. • Rock compressibility in an overpressured reservoir. • An inflow that gradually decreases over time, perhaps because of depletion or because flow across the fault decreases/ ceases below a certain pressure threshold.

In cases where fluid inflow is suspected, knowledge of the reservoir geometry is an absolute requirement to limit the possible reasons for either an upward or downward curving trend.

RESERVOIR ISSUE 3 • MARCH 2008 27 (...Continued from page 27) • Pressure gradients across the reservoir are more pronounced, due to the oil viscosity. • Pressure differences in an oil column, due to the density of the oil, are sufficient to require careful correction to a common datum. • Multiple perforation intervals and inadvertent commingling of intervals that were isolated by nature creates the potential for crossflow and further confuses the pressure data interpretation.

Other potential sources of error include: • Thermodynamic equilibrium is not attained. • PVT data that does not represent reservoir conditions. • Uncertainty in the “m” ratio. • Inaccurate production allocation.

Yet despite the foregoing theoretical and practical challenges, material balance analysis has proven its worth, with the accuracy of the analysis generally increasing as the reservoir is produced. In Fekete’s experience, the most reliable analyses are obtained by integrating the reservoir geology; Figure 4.

RESERVOIR ISSUE 3 • MARCH 2008 29 THE NEOPROTEROZOIC OLD FORT POINT FORMATION, Southern Canadian Cordillera | by Mark D. Smith, R.W.C. (Bill) Arnott, and G.M. Ross

Part 1: Historical Background and Stratigraphic Formalization

INTRODUCTION Regional stratigraphic markers are essential for reconstructing large, poorly fossiliferous sedimentary systems. In the same way that the forms part of a pan- North American series of nearly isochronous black shales, the Old Fort Point Formation (OFP) of the Neoproterozoic Windermere Supergroup (WSG) is a unique stratigraphic marker that provides a key element in reconstructing the WSG sedimentary basin and linking it with coeval global events. The OFP is a predominantly fine-grained mixed siliciclastic / carbonate marker unit, locally exposed over an impressive area of 35,000 km2 in the southern Canadian Cordillera (Figure 1), and key for regional stratigraphic correlations. The WSG has long been plagued by complex stratigraphic nomenclature due largely to its indistinct (some would say monotonous) lithologic character, immense size of the depositional system, structural complexity, and small study areas (Figure 1). These uncertainties have resulted in a complex and commonly confusing stratigraphic nomenclature for not only strata of the OFP, but the entire WSG (Figure 2).

The distinctive nature and widespread occurrence of the OFP led to its recognition by several authors as a significant and correlatable horizon throughout the southern Canadian Cordillera. Stratigraphically upward, the OFP comprises three lithological units:

1) fine-grained siltstone-mudstone that Figure 1.

The name “Old Fort Point” comes from a prominent local landmark south of the Jasper townsite where accessible exposures of the unit are located (Figure 3A). C. R.

mapped. Very poorly sorted conglomerates are typical of proximal alluvial fan settings; sorting generally increases eastward such that moderately sorted medium- to coarse- grained sandstones with minor pebbles are common in fluvial strata of the Spirit River Valley (Figure 4).

Conglomerates are typically litharenites, with well rounded chert pebbles ranging from granules up to several centimetres in diameter. Sorting is poor, with finer sands filling interpebble pore spaces; only rarely is pebble-supported porosity observed. Finer sandstones feature more quartz and better sorting overall. Sedimentary rock fragments are locally common, as are coal and mud clasts. Less common accessories include detrital carbonates, feldspars, and igneous/ metamorphic rock fragments. (Continued on page 36..)

Figure 1. Cadomin situation map, Western Canada. Fox Creek Escarpment is updip depositional edge of Cadomin. West of the Deep Basin edge, Cadomin strata are gas saturated, and gas can be produced wherever there is sufficient permeability. To the east, gas and oil are produced from conventional stratigraphic and structural traps.

RESERVOIR ISSUE 3 • MARCH 2008 35 is isolated production from Foothills fractured reservoirs at Ojay / Hiding Creek (northeastern B.C.), and at Chinook Ridge / Narraway (west-), but some of this is commingled with the Nikanassin, so that the Cadomin contribution is difficult to differentiate.

Reliable resource estimates are not available for the Cadomin. Both GSC and Canadian Gas Potential Committee assessments combine the Cadomin within several play types. More importantly, existing resource assessments do not address significant strides made within the last few years in producing gas from low- permeability Cadomin reservoirs.

Burlington locally developed considerable permeability High River in southwestern Alberta. There Canada (now ConocoPhillips) and other as the result of small- to moderate-scale fracturing (Figures 2, 4). In places, core is rubbled or has not been recovered.

Core analyses show very low porosities (commonly <5%) and permeabilities (<0.5 mD, with many values <0.1 mD) in deep Cadomin sections in the western parts of the basin. Where fractures occur, porosity values remain low, but permeabilities are in the 0.5-10 mD range, with spikes to 100 mD+ corresponding to larger fractures. Updip toward the Deep Basin edge, reservoir quality improves to 5-10% porosity and 1-10+ mD, reflecting less extensive diagenetic degradation. Pressure transient analyses indicate in situ permeabilities of 0.01 to 0.5 mD.

Conventional well log suites are reliable in assessing Cadomin lithologies and porosity. Permeabilities are more difficult to assess, however, because of variations arising from grain size, sorting, and fracturing. Locally, bitumen or pyrobitumen may appear as Figure 5. Thin section showing relatively poor intergranular porosity and cross-cutting fractures within chert porosity on porosity tools. pebbles. Partially filled fractures impart limited permeability fairways within Cadomin strata.

36 RESERVOIR ISSUE 3 • MARCH 2008 operators have also aggressively pursued the Cadomin at Cutbank Ridge since 2003. To the northwest at Groundbirch, intensive drilling since 2005 for deeper targets has extended the Cadomin Deep Basin edge play fairway.

The updip edge of the Cadomin Deep Basin is well defined by gas production downdip, and formation water tests updip. Isolated water recoveries in the Deep Basin may be attributed to locally trapped “perched” water accumulations, or to mud filtrate recoveries. Almost every well completed in the Cadomin Deep Basin has flowed some gas, but economic rates and reserves (at reasonably projected gas prices) are limited to better reservoir rock found in a narrow band along the Deep Basin updip edge.

Cutbank Ridge is a good example of modern engineering technology and elevated long-term gas prices making a previously uneconomic “tight” gas play economic. The Cutbank Ridge area itself does not appear to be unique in terms of Cadomin reservoir characteristics, and current drilling is expanding the play northwestward toward Groundbirch and southeastward toward Wapiti.

Hooker / High River Field Cadomin strata (locally termed the Basal Quartz) lie within a north-south trending valley system in the Hooker / High River area, part of a more regional valley mappable over 150 km. Drilling depths range from about 2,300 metres in the north to more than 3,200 metres in the southern part of the valley trend (Figure 6).

Gas was discovered in conventional traps in the Basal Quartz valley fill to the north at Crossfield in the 1960s. Spence (1997) mapped the Basal Quartz valley system southward, into an area with little well control. Reservoir quality deteriorated downdip, and conventional traps were difficult to define. Following Spence’s work, Compton Petroleum identified an extensive Cadomin / Basal Quartz fairway in the Hooker / High River area, and assembled an extensive land position. In 1999, they participated in the High River discovery well, which demonstrated that gas was present and producible. Today, Figure 6. Situation map, Cadomin / Basal Quartz at Hooker / High River. Intensive development has taken place the Hooker / High River development covers downdip of the Deep Basin edge, at depths where economic porosity and permeability are preserved.

In situ values are probably some wells. Sandstones are finer grained and isolated sweet spots with better sorting considerably lower, as the reservoir is buried less pebbly than the Cadomin to the north, and/or coarser grain size exhibit 20-80 mD to almost 3,500 metres at this location. and have experienced significant degradation permeability.
