LP-SAGD: Lab Testing of Artificial Lift Systems JIP

In large regions of the Athabasca oil sands, where SAGD recovery techniques are currently being used or considered, the presence of a depleted or naturally low–pressured formation directly above the reservoir makes it necessary to operate the producing wells at relatively low pressures. It is still uncertain if current artificial lift systems can operate efficiently and reliably at these low pressures, especially at low degrees of sub-cooling (i.e. close to steam saturation conditions). It is the objective of this JIP to test a number of downhole and surface–driven pumping systems at low intake pressures and low degrees of sub–cooling in a laboratory environment to prioritize and select candidates for further field trials.
