The objectives of this project are to: (1) conduct reservoir studies, laboratory tests, simulation runs, and field tests to evaluate the use of foam for mobility control or fluid diversion in a New Mexico C0{sub 2} flood, and (2) evaluate the concept of C0{sub 2}-foam in the field by using a reservoir where C0{sub 2} flooding is ongoing, characterizing the reservoir, modeling the process, and verifying the effectiveness. Seven tasks were identified for the successful completion of this four-year project: (1) evaluate and select a field site, (2) develop an initial site-specific plan, (3) conduct laboratory C0{sub 2}-foam mobility tests, (4) perform reservoir simulations, (5) design the foam slug, (6) implement a field test, and (7) evaluate results. Accomplishments for the following topics are presented: project planning; surfactant selection; foam slug design; project monitoring; and reservoir simulation studies.
