2000-2008
Recovered an additional 104 million barrels of incremental oil.
Project will extend life of the facility by 25 years.
EOR incremental production for Weyburn: 15,000 bbl/day.
More than 1.7 million tonnes of CO2/year sequestered at Weyburn CO2 Enhanced Oil Recovery project.
Challenges
- Encana Corporation set out to build largest CO2 flood operation in Canada.
- The project would involve unprecedented technology with no regulatory framework in place and a long project payout period.
Solutions
- Provided EPCM services for the installation of all surface facilities for the original Weyburn CO2 miscible flood.
- Original surface facilities at the Central Process Unit included inlet separation, FWKOs, two 6,000-HP CO2 recycle compressors, CO2 dehydration, produced water injection, and 55 km of high-pressure CO2 distribution pipelines.
- Expansion and upgrading projects included installation of a two-stage 17,500 HP CO2 recycle compressors, two CO2 dehydration facilities sized for 5,000 t/day of recycled CO2, 530 m3/hr water injection pump, new transformer, a 30,000 bbl water storage tank with booster pumps, and upgrades to FWKO system.
- Field facilities included all production/injection satellites, and production/injection pipelines.
Highlights
- Proved technical and economic feasibility of carbon storage in geological formations.
- Proved CO2 injection as a viable method for Enhanced Oil Recovery (EOR).
- Provided $3.5 billion in added value to the provincial economy.
Project numbers
45 million net tonnes of CO2 projected to be stored over the project life6000 t/d of CO2 injection, 1.8 Mt/yr of CO2 injection (equivalent to 600,000 cars off the road for a year)
