The University of Texas of the Permian Basin - Principal Investigator: Robert Trentham
Objective: The objective of the project is to delineate presence and size of Residual Oil Zone (ROZ) resources in ROZ “fairways” in the Permian Basin of Texas and New Mexico. In the Permian Basin of Texas thick ROZ’s exist immediately below many oil fields productive from the San Andres dolomite. The zones can contain 20 to 40% residual oil in pore spaces. This oil cannot be produced by conventional production techniques, including water flooding. A ROZ CO2 flood is underway in the Seminole field and early projections suggest the project may recover 200-300 million barrels of additional domestic oil. In addition to examining the Texas resource in more detail, the study would develop technology for finding the higher quality portions of the ROZ resource recoverable with CO2 EOR directed toward the small oil producers within the Permian Basin and other ROZ basins within the U.S.
