CO2 Injection has been used successfully throughout which geological region?

CO2 Injection has been used successfully throughout which geological region?

• A. Gulf Coast
• B. Bakken
• C. Marcellus
• D. Permian Basin

Answer: (D)

CO2 injection works best when the geology supports a long, continuous sweep and there's a steady supply of CO2 nearby. The Permian Basin provides that combination: many mature oil reservoirs with thick, permeable rock layers that respond well to gas floods, plus an established network and sources of CO2 that make large-scale injections economical. In these conditions, CO2 can displace oil effectively, reduce oil viscosity, and, at the right pressures, reach miscibility with oil to push it toward production wells. Over decades, this has allowed CO2 flooding to be implemented across numerous fields in the basin, demonstrating reliable, across-the-board gains in recovery. While CO2 EOR is used in other regions as well, the Permian Basin has the broad, sustained track record that makes it the standout example of successful, widespread CO2 injection.
