As conventional oil and gas reservoirs become depleted, interests for unconventional petroleum resources has rapidly increased in the last decade. Due to high production cost and needs for high production technology in oil and gas development, the unconventional petroleum resources have not been focused in the past. The unconventional resources include oil sands in Canada, extra heavy oils in Venezuela, and oil shales in a number of countries. A total of reserves were estimated over 6 trillion barrels in original oil in place(OOIP).
Heavy oils are divided into four types, medium heavy oil, extra-heavy oil, tar sands/bitumen, and oil shale, respectively. Of these, heavy and extra-heavy oils have mobility, but not in bitumen. Oil shale has generally very low permeability. The largest oil sand deposits are in Alberta, spatially grouping into three development areas, the Athabasca, Cold Lake, and Peace River. Principal oil sands deposits consist of the McMurray Formation and Wabiskaw Member in Athabasca area, the Gething and Bluesky Formations in Peace River area, and relatively thin multi-reservoir deposits of McMurray, Clearwater, and Grand Rapid Formations in Cold Lake area. On the basis of core and well-logging data analyses collecting in that region, seven geologic maps were produced for reservoir characterization of major oil sands. Reservoir geologic characterization using a AccuMap tool revealed that the McMurray Formation appear to be controlled by paleo-topography of the Cretaceous carbonate basement. In order to understand sedimentary facies distribution in three dimension mode, geological modeling with fault pattern analysis has been conducted, reflecting the development aspects of sand and mud deposits characteristic in the McMurray Formation.
The largest extra heavy oil reservoirs occur in the Orinoco Oil Belt in Venezuela. The extra heavy oils are extremely heavy hydrocarbons, in situ viscosity of 100-10,000 cP at reservoir condition and API gravity between 7-20o with limited mobility under in-situ reservoir condition. The oil belt contains an estimated 1.3 trillion barrels of original oil-in-place and 250 billion barrels of established reserves. The Orinoco Oil Belt comprises four major production blocks, Boyaco, Junin, Ayachoco, and Carabobo. Nowadays, PDVSA makes a development of each production block with a number of foreign oil companies, forming an international joint-venture company. In Boyaco and Junin development areas, the reservoirs occupy regionally in larger area, whereas, in Ayachoco and Carabobo, the extra heavy oils are characteristically accumulated in a narrow region. The major production area is currently Junin and Carabobo blocks, due mainly to thick reservoirs in wider area and hence good facilities related to oil production. The reservoir depth of extra heavy oil in Orinoco is approximately 350-1,000 m below the ground, depending on the blocks. The geologic reservoir characterization for individual blocks is thus definitely needed for the development of heavy oil in the region. The Miocene Oficina Formation in Maturin subbasin(Junin, Ayachoco and Carabobo) is a principal reservoir formation in the Orinoco Oil Belt. The formation comprises alternations of a few meters- to decimeters-thick sand and mud beds. It was formed in fluvial-estuarine-deltaic environments with great reservoir complexity and heterogeneity. In western region in the Orinoco Oil Belt, the reservoir is the stacked estuarine mouth-bar deposits, by contrast deltaic channel deposits are extensively developed along the eastern block. Such reservoir complexity and heterogeneity have raised an interest and promoted R&D investment in reservoir geology and geological characterization in the field of extra heavy oil development in Venezuela.
Oil shale generally refers to a sedimentary rock that contains solid bituminous materials (called kerogen) that are released as petroleum-like liquids when the rock is heated in the chemical process of pyrolysis. Oil shale was formed by deposition of silt and organic debris on lake and sea bottoms. Over long periods of time, heat and pressure transformed the organic matters and sediments into oil shale. Extracting oil from oil shale is more complex than conventional oil recovery and currently is more expensive. The oil substances in oil shale are solid and cannot be pumped directly out of the ground. The oil shale must first be mined and then heated to a high temperature (a process called retorting). The resultant liquid must then be separated and collected. An alternative but currently experimental process referred to as in situ retorting involves heating the oil shale while it is still underground, and then pumping the resulting liquid to the surface. Oil shale deposits are Cambrian to Tertiary in time and occur in variable sedimentary environments from lake to marine environment. The Eocene Green River Formation spanning from Colorado and Utah, to Wyoming and Devonian to Mississippian Black Shale in Eastern United State are major oil shale deposit. Recent research reported that even for oil shale reservoir characterization should be carried out to improve the efficiency for production. In case the Green River Formation, major oil shales are Mahogany calcareous zone and Upper R-6 dolomitic/siliciclastic deposits. The geologic characterization of oil shale deposits were successfully conducted to find out the core region for development.
Modem analogue study for extra heavy oil in Orinoco Belt was carried out in the Yeonggwang coast, west coast of Korea. High-resolution seismic profiles using a Sparker and Chirp system were acquired along the shallow tidal sea area. Based on seismic analysis, three drill cores taken on the estuarine tidal flat were analyzed to examine channel-fill aspects and stacking pattern of sand and mud beds. The estuarine tidal deposits and its stratigraphic evolution pattern are very similar to Miocene Oficina Formation in Orinoco extra heavy oil belt. It can be thus applicable for reconstructing paleoenvironment and further tracking reservoirs.
This research program gathers a variety of raw data, reported .data, analytical data, and information on unconventional petroleum resources. Based on the data and information, this program has summarized geological characteristics of the unconventional petroleum resources and oil fields. Furthermore, it obtains recent information on development status and future of the unconventional petroleum resources. It will provide a basis for establishing a future-strategy of advance into world unconventional oil and gas market, and will reconstruct a basic information-system for planning a government policy for secure of foreign petroleum resources.
