The most significant deposits of tar sands are located in Alberta, Canada. Alberta contain an estimated 92 billion bbl of bitumen trapped in an updip pinch-out of the Lower Cretaceous Bluesky and Gething formations. Best reservoir developments are found in barrier bar, transgressive tidal sand ridges, subtidal channels, and point bar facies. The Crow Reservation area, located in south-central Montana, is part of the Rocky Mountain Foreland structural province, which is characterized by Laramide uplifts and intervening structural basins. The region overlays a large bitumen deposit of the same name. As of 2016, human footprint occupied 21.18% of the Peace River OSA. The heavy oil and sand re brought to the surface and separated in storage tanks. The Peace River oil sands of northwestern Alberta contain an estimated 92 billion bbl of bitumen trapped in an updip pinch-out of the Lower Cretaceous Blueksy and Gething Formation. Modern analog to this fan-delta system is the coastal fans of the Gulf of Aqaba, Red Sea. This sequence differs slightly from that of the Recent classic regressive Galveston Island, Texas, and the ancient Muddy barrier island, Montana, in the presence of an ebb-tidal delta and marine shelf shales beneath and above the middle shorefacies, respectively. Isopach maps from the top of the Bluesky and Gething Formations. Location of Alberta oil sands deposits: Map showing the location of the Athabasca, Cold Lake, and Peace River oil sands deposits in Alberta, Canada. Thin discontinuous shale laminae or shaly wisps merely impede flow. The erosional surface at the base of the Greybull Sandstone is the +100 Ma, late Aptian-Early Albian regional unconformity of Weimer (1984). Projects. Two examples are presented which illustrate the extraction of data for a wide variety of standard geological (structure and isopach) and resource (oil, gas, and water sands) maps. Similar trends are seen in the main sand bodies. Geol.) Subsurface mapping, incorporated with surface data, has revealed five major Greybull channels crossing the Crow Reservation. Well log analyses were calibrated to core analyses as about one-third of the wells were cored in this stratigraphic interval. Institute @2018. Coordination of computer-generated maps with the facies model highlights areas which satisfy specific criteria that may be critical in determining the applicability of a particular in situ recovery method. Pet. Grande Prairie New Methanol Plant Project. With sparse reservation well control, subsurface structural and isopach maps are highly interpretive. Standard geologic exploration techniques, such as sand isopachs and paleostructure maps, are of limited value in exploring for new fields in areas where well control is sparse or absent. The reservation area east of the mountains is on the northwestern flank of the Powder River Basin. Assoc. The barrier island trends northwest-southeast parallel to the paleostrandline for more than 120 km (75 mi) and attained a maximum thickness of more than 30 m (100 ft). However, only limited petroleum production has been established within the reservation. A computerized data file on each well consists of basic well data, tops of the Bluesky and Gething Formations, and oil sand reservoir and the underlying pre-Cretaceous unconformity, and a coded lithology log.

Logs have been calibrated wherever possible with core control. ; (United States).
