Paper presented at the Canadian Unconventional Resources Conference, November 15–17, 2011
Paper Number: SPE-149274-MS
... Abstract The SAGD process utilizes horizontal wells hence permeability anisotropy can play a very strong role in recovery. In fact, it has been well documented that poor vertical permeability kills the SAGD process because the steam chamber will not grow properly. Several authors have attempted...

Paper presented at the Canadian Unconventional Resources Conference, November 15–17, 2011
Paper Number: SPE-148847-MS
..., a coupled geomechanical simulation that solves the flow and stress equation simultaneously in the reservoir is crucial for modeling the SAGD process. The objective of this paper is to construct a 3D geostatistical model for the Surmont pilot and implement coupled geomechanical modeling for the SAGD process...

... of processes to unlock this type of resource is important and critical to further growth of in situ oil sands recovery in Alberta. The results provide a technical basis to construct feasible low-pressure ES-SAGD processes for this type of reservoir. steam-assisted gravity drainage overburden steam...

... to the overlying thief zone will be more significant when a top water zone is present. However, an optimal operating strategy for the full field scale SAGD process with both top gas and top water remains uncertain. The objective of this paper is to construct a 3D geostatistical model for a Surmont pilot...

Paper presented at the Canadian Unconventional Resources and International Petroleum Conference, October 19–21, 2010
Paper Number: SPE-137001-MS
... Abstract The presence of an oil viscosity gradient appears to be a real phenomenon in the field and its influence on the SAGD process has been studied by various researchers. However, there is potential to refine previous results to exploit the impact of viscosity gradients on SAGD oil recovery...

... simulation. The results of this research provide guidelines on how to implement the SAGD process in shallow oil sands reservoirs with no cap rock. This could unlock a resource that is currently considered inaccessible. The results show that vertical chamber growth can be controlled to some extent by using...

Paper presented at the Canadian Unconventional Resources and International Petroleum Conference, October 19–21, 2010
Paper Number: SPE-138170-MS
... Abstract Steam assisted gravity drainage (SAGD) is demonstrated as a proven technology to unlock heavy oil and bitumen in Canadian reservoirs. One of the long-term concerns with the SAGD process is high energy intensity and related environmental impacts. Addition of potential alkane solvents...
