Implementation of a CO2 Foam Pilot Study in the SACROC Field: Performance Evaluation

Abstract

Abstract A new conformance solution has been developed to help producers reach and recover more oil from existing wells while simultaneously reducing operating expenditures. This new technology successfully addresses shortcomings associated with existing miscible gas EOR (enhanced oil recovery) processes by generating foams of supercritical CO2 fluid and water in the formation which alter mobility and improve vertical conformance. Ultimately, the process can improve the profitability of existing wells by enhancing reservoir sweep efficiency, thereby allowing access to previously bypassed oil. This report describes the technology development process and documents successful field trial results from Kinder Morgan's SACROC field.
