This course provides an in-depth understanding of Miscible Gas Enhanced Oil Recovery (EOR) methods, the corresponding displacement mechanisms and expected performance. Il also provides information about miscible gas EOR projects workflow based on the presentation of screening criteria and field cases.
Public :
