Unconventional reservoirs typically yield less than 10% oil recovery. In the Permian basin, enhanced oil recovery (EOR) schemes include CO 2 injection, huff and puff, water injection, and, to a lesser ...

Enhanced oil recovery (EOR) in unconventional reservoirs has been stymied by its low-permeability, low-porosity environment. Liberty Resources performed water-alternating-gas (WAG) EOR pilot tests in ...

A waterflood pressurizes the reservoir and sweeps oil toward producers by injecting treated water into designated injection wells. It is the workhorse of secondary recovery, extending plateau rates, ...

CRANE COUNTY, Texas — There’s one thing you won’t find at the Antina Ranch: cows. That’s because test showed Antina’s main water well was tainted with contaminants such as benzene, chloride, sulfate ...
