Weyburn Carbon Capture Utilization and Sequestration Project

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

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)
