Gulf Canada Resources – Swan Hills

  • Conducted a mechanical reliability study for the 65 km of produced water pipelines, 50 km gas gathering, and oil flowlines (ranging from 4” diameter to 12” diameter). The system flows were 7500 bbl/d oil, 50 MMSCF/d gas and 190,000 bbl/d water.
  • Conducted system improvement studies for the above gas gathering and produced water injection pipelines
  • Carried out the economic evaluations for various production gain scenarios involving reliability improvement for the gathering and produced water injection systems
  • Investigated the reliability effect, environmental risk reduction, and the production improvement associated with the rerouting of the production from seven oil wells. The system flows were 4 MMSCF/d gas, 650 bbl/d oil, and 24,000 bbl/d water.
  • Designed flare system modifications at the miscible flood plant in order to avoid utilization of the flare pit. The modifications included a flash drum system to separate the phases — gas to flare, liquids reinjected in the NGL line.
  • Prepared equipment specifications for the stated modifications at the miscible flood plant and conducted the bid evaluations and procurement
  • Field facilities involving 300 wells, 7500 bbl/d of oil associated with 50 MMSCF/d of gas, and 190,000 bbl/d of water were studied for optimization purposes. Production modes included water flood and miscible flood. A concept of super satellites was developed for energy conservation and gathering system debottlenecking. Weak links in the injection system were identified for prioritized line replacement, thereby avoiding major production interruption costs. Operating cost improvement opportunities were identified through shifting the make-up water source from surface to underground aquifers. The centralization approach yielded significant operating efficiencies with respect to water handling and injection. Simultaneously, serious environmental issues and corresponding revenue implications were addressed.
