Weyburn Carbon Capture Utilization and Sequestration Project

Part of the Enhanced Oil Recovery (EOR) projects for the combined Weyburn-Midale oil field

Encana Corporation | Canada | 2000-2008

Recovered an additional 104 million亚博体育开户 barrels of incremental oil

Project will extend life of the facility by 25 years

EOR incremental production for Weyburn: 15,000 bbl/day

Challenges

  • Build largest CO2 flood operation in Canada
  • Unprecedented technology with no regulatory framework in place
  • 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, FWKO’s, two 6000-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

Projected to store 45 million net tonnes of CO2 over the project life
6000 t/d of CO2 injection, 1.8 Mt/yr of CO2 injection (equivalent to 600,000 cars off the road for a year)
