Geophysical imaging technology provides insight on EOR practices ///

Various enhanced oil recovery (EOR) techniques have been pursued at Naval Petroleum Reserve No. 3 (NPR-3) since before the Rocky Mountain Oilfield Testing Center (RMOTC) was created on the site by the Department of Energy in 1994. NPR-3 is situated north of Casper, Wyoming, in the Powder River basin on the Teapot Dome anticline. It has over 600 active wells producing oil and gas from several different geologic formations at depths ranging from 500 ft to 5,000 ft. Recently, RMOTC partnered with two testing companies to analyze the results of waterfloods and modify the programs going forward. They conducted tests using their technologies to monitor fluid movement in the Shannon Sandstone. Information obtained from these surveys facilitates the understanding of how waterflood practices are likely to influence oil production, and how the reservoir may be managed and monitored to optimize oil production.
