LP-SAGD: Wellbore Architecture Alternatives Joint Industry Project

Until very recently, most SAGD projects have used a combination of high-pressure steam injection, natural steam lift, and gas lift to transport the produced fluids to surface. However, in large regions of the Athabasca oil sands, the presence of a depleted or naturally low pressured gas and water bearing formation directly above the reservoir makes it necessary for producers to operate the producing and injection wells at much lower pressures to avoid steam chamber losses. Also, the high cost of natural gas and the added energy required to generate high-pressure steam are encouraging producers to move to lower steam injection pressures to reduce steam–oil ratios.

The LP-SAGD Wellbore Architecture JIP was initiated to address issues such as suitable wellbore designs, drilling and completion equipment requirements, effects on the SAGD production process, and matching of AL technologies with these well designs.
