Item The controls on reservoir continuity within the late Mississippian Elkton Member at Caroline Field, Central Alberta, Canada.(2014-06-11) Kuijper, Kimberley E.; Atchley, Stacy C.; Geology.; Baylor University. Dept. of Geology.Caroline Field, located in Alberta, Canada, was discovered in 1954 and currently has recovered 96% of its 68.3 mmbbl of recoverable oil reserves from the Mississippian Elkton Member (recovery factor of approximately 38%). Additional residual oil reserves at Caroline may be produced through enhanced recovery if carefully guided by a detailed stratigraphic framework. This study focuses on two hydrocarbon operational units within Caroline Field; Sundre Unit #1 and Sundre Rundle B. Detailed core description was conducted on 49 wells within the area. Using the core descriptions and core analysis data acquired from IHS AccuMap®, statistical methods were utilized to understand reservoir quality within the Elkton Member of the Turner Valley Formation. A sequence stratigraphic model was constructed to determine reservoir continuity. The mapping of gross pore volume calculations and flow unit continuity identifies areas where tertiary recovery methods are most likely to be effective.Item Geology of the Late Pleistocene artifact-bearing Wasiriya Beds at the Nyamita locality, Rusinga Island, Kenya.(2011-12-19) Van Plantinga, Alexander A.; Peppe, Daniel J.; Geology.; Baylor University. Dept. of Geology.This study investigated the sedimentology and stratigraphy of the Late Pleistocene Wasiriya Beds at the Nyamita locality on Rusinga Island, Kenya in northeastern Lake Victoria. Little is yet known about this region during the Pleistocene. This study provides geological context for archaeological research of the stone artifacts in the Wasiriya Beds, for the paleontological work on the fauna of these beds, and for other paleoenvironmental research in these beds. A robust tephrostratigraphic framework was established using diverse statistical methods. Radiocarbon dates confirm a Late Pleistocene age for these deposits. A valley-drainage model was integrated with a facies model to infer their paleoenvironmental history. Sediments suggest a generally sharply alternating wet and dry seasonality. Geological evidence does not suggest that the Lake Victoria region was especially arid just prior to the Last Glacial Maximum. Additional data from the lower Wasiriya Beds could elaborate on their paleoenvironmental significance.
