Tensleep reservoir study, Oregon Basin Field, Wyoming: reservoir characteristics

Conference ·
OSTI ID:7322086
Engineers and geologists worked together to perform a reservoir study of the Tensleep at Oregon Basin. Oregon Basin Field, located in northwestern Wyoming, has produced over 122 million barrels of Tensleep oil. Layers of non-reservoir material separate the Tensleep into zones that perform as discrete reservoirs. Some zones have been completely eroded in portions of the field by post-Tensleep streams. Maps of individual zones reveal a complex reservoir distribution, which was caused by a combination of original depositional characteristics, post-depositional erosion, and cementation. Since little or no cross flow occurs between zones, each zone must be managed separately if optimum oil recovery is to be achieved.
