The "Post Waterflood CO2 Miscible Flood in Light oil Fluvial Dominated Deltaic Reservoir" is a Class I DOE-sponsored field demonstration project of a CO2 miscible flood project at the Port Neches Field in Orange County, Texas. The project will determine the recovery efficiency of CO2 flooding a waterflooded and a partial waterdrive sandstone reservoir at a depth of 5800'. The project will also evaluate the use of a horizontal CO2 injection well placed at the original oil-water contact of the waterflooded reservoir. A PC-based reservoir screening model will be developed by Texaco's research lab in Houston and Louisiana state University will assist in the development of a database of fluvial~dominated deltaic reservoirs where CO2 flooding may be applicable. This technology will be transferred throughout the oil industry through a series of technical papers and industry open forums.
