Abstract The residual oil saturation determination is critical for the performance evaluation of any Enhance Oil Recovery (EOR) methods. The existing residual oil saturation determination methods are mainly based on solvent extraction. However, because the quality of the extracted residual oil and the remaining spent rock samples have not been ...

Steam Assisted Gravity Drainage (SAGD) In Horizontal Wells: A Visualization Model Study
International Thermal Operations and Heavy Oil Symposium, 1997Abstract The successful testing of a gravity drainage process, using the horizontal wells in the Underground Test Facility (UTF) in Alberta, Canada indicates that high recovery and economical oil-steam ratios are achievable. However, several major technical challenges must be resolved to extend this successful pilot

Novel Scale Remediation for Steam Assisted Gravity Drainage (SAGD) Operations
SPE International Symposium on Oilfield Chemistry, 2013Abstract Shell runs a Steam Assisted Gravity Drainage (SAGD) operation at the Orion field in Alberta, Canada. Pressure drops during bitumen and water recovery can lead to precipitation and buildup of scales which can plug up well equipment and lead to an increase in differential pressure and lower production.

Screening and Design Criteria for Steam Assisted Gravity Drainage (SAGD) Projects
SPE International Conference on Horizontal Well Technology, 1998Abstract Certain insights into screening and design of SAGD projects, derived from in-depth analyses of three successful field projects in Canada [Tangleflags, Underground Test Facility (UTF) and Imperial Oil's Horizontal Well Pilot I (HWPI) projects] are presented.

Numerical And Experimental Modelling of the Steam-assisted Gravity Drainage (SAGD) Process
Annual Technical Meeting, 1999Abstract The experimental studies carried out to evaluate oil recovery processes let optimum strategies be determined and necessary actions be taken before initiating a new project. Numerical simulators can, sometimes, perform same tasks in a much more economical and faster way, with many alternatives.

Analysis of the Steam Assisted Gravity Drainage (SAGD) Process Using Experimental/Numerical Tools
Proceedings of International Conference on Horizontal Well Technology, 1996Abstract There has been a keen interest during the last decade in the application of the steam assisted gravity drainage (SAGD) process as a recovery strategy for oil sands and heavy oil reservoirs. The recent success of field pilot demonstrations in Alberta and Saskatchewan has further accentuated the need to understand process ...

Modeling the Effect of Permeability Anisotropy on the Steam-Assisted Gravity Drainage (SAGD) Process
Canadian Unconventional Resources Conference, 2011Abstract 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.

Transient convective heat transfer in a steam-assisted gravity drainage (SAGD) process
Fuel, 2019Abstract Viscosity reduction through heat transport from steam to bitumen is one of the most important recovery mechanisms of a steam-assisted gravity drainage (SAGD) process. Both heat convection and conduction contribute to the heat transport. Although conduction is considered as dominant through most of a SAGD process, an understanding of heat ...
