Low recovery (10%) from the Spraberry Trend including marginally economic waterflood recovery has marked the Spraberry Trend with its 8 billion bbl remaining oil-in-place as a target for enhanced oil recovery. However, the fractured nature of the reservoir had precluded previous CO2 flooding, and resulted in a lack of confidence in the application of water injection. The objective of this project is to demonstrate the economic viability of recovering incremental oil reserves from the Spraberry Reservoir covering over one half million acres in the Permian Basin of West Texas. The pilot study indicates that additional 5-8% of additional oil in place can be recovered by more efficient practices and would increase recoverable reserves in the Spraberry by 500 to 800 million barrels of oil. The expansion of the original Class project as a (PUMP) project studied the waterflood response and demonstrated successful waterflood strategies for the Spraberry.
