Application of CT imaging to study oil recovery from naturally fractured reserviors
- Texas A&M Univ., College Station, TX (United States)
The proposed presentation focuses on the effectiveness of applying the carbonated water inhibition process to the Austin Chalk Formation which is a naturally fractured producing system. The distribution of oil in the Austin Chalk between oil in the matrix blocks and the fractures is unknown. Opinions vary as to whether the matrix blocks actually contain oil movable oil. A method to study recoveries using both the oil saturated matrix block case and oil in the fracture only case has been developed. The complex fracture and multiple matrix block model experiments were run to compare recoveries of simple water inhibition to carbonated water iminhibitionThe results of this study more accurately illustrate the physical mechanisms of imbibition and the benefits of carbonation to the imbibition process. In addition, recoveries from experiments with oil contained in the fractures only were found to be increased by 25%. Recoveries in oil saturated matrix blocks experiments were enhanced by 13% with a six fold acceleration in this enhance recovery.
