Update Case History: Performance of the Twofreds Tertiary CO₂ Project Available to Purchase

The performance of the first Texas field-scale tertiary CO₂ injection project in a sandstone formation is updated. The Twofreds tertiary CO₂ injection project was developed in two phases. The east side of the reservoir was initiated in February 1974 and is now essentially completed. Expansion to the west side started in the early 80’s. Detailed evaluation of the actual performance of the east side CO₂ flood will be presented along with operations, design, and monitoring considerations.
