RE:CNQ KNOCKS OUT CVE As TOP TMX SHIPPER To 164,000 Bbls/d - CNQ has 5 SAGD sites producing ~372,000 bbls/d of BITUMEN
CORRECTION:
- CNQ has ONLY 2 SAGD sites:
* Kirby: 80,000 bbls/d
* Jackfish: 120,000 bbls/d {just West of CVE Chistina Lake}
- CNQ has 3 CSS sites:
* Wolf Lake / Primrose: 140,000 bbls/d
* Peace River: 12,500 bbls/d CYCLIC STEAM STIMULATION (CSS)
- A single well is drilled into the oil sands deposit.
- High pressure steam is injected into the reservoir to heat the bitumen and reduce its viscosity (1). This steam continues to be injected for several weeks in order to fully saturate the reservoir.
- The bitumen is then allowed to soak for several days or weeks in the hot pressurized reservoir (2).
- As the reservoir cools, this provides the driving force to bring the oil up to the surface. The flow is then reversed so that the bitumen/water emulsion can be pumped up to the surface. This production phase (3) can last for several weeks.
- At the processing plant, water is removed from the bitumen, treated and recycled back into the process. The bitumen is typically diluted with condensate, and sold directly to market.
