CO{sub 2} foam: Results from four developmental field trials
- Mobil Oil Corp., Dallas, TX (United States)
Four pattern-scale CO{sub 2}-foam field trials were conducted to determine the effectiveness of foam in reducing CO{sub 2} channeling, to evaluate the economic potential of the process, and to develop application criteria and procedures. The trials were conducted under various process and geologic conditions so that the resulting technology would be applicable in a number of different CO{sub 2} floods. Two different surfactants, Rhodapex (formerly Alipal) CD-128 and Chaser CD-1045, and two injection methods, alternating vs. coinjection of CO{sub 2} and surfactant, were tested in San Andres (west Texas) and platform carbonate (southeast Utah) reservoirs. In all, 161,000 lbm of active surfactant was injected in the four field trials, with one well undergoing foam treatment for as long as 18 months. The treatments resulted in a significant reduction in a gas production and indications of increased oil production. The total cost of the four treatments (excluding labor and overhead) was $700,000.
