... alternatives. Some of the complexity of oil recovery process, such as SAGD(Steam Assisted Gravity Drainage), can be resolved by carrying out experimental and numerical evaluations together. In this study, numerical simulation of the SAGD process is performed. The CMG "STARS" ™ thermal simulator was used...

.... An understanding of this mechanism and its optimal timing are important in enhancement of the SAGD process. Introduction More than 52 billion cubic meters (330 billion barrels) of bitumen are believed to be in place in the Athabasca oil sands deposit in Canada, which are recoverable using the Steam Assisted...

... a heavy oil/oil sand reservoirs with a contiguous water sand (water which may lie below or above the oil-bearing zone) is risky due to the possibility of short circuiting the steam chamber. The success of the Steam Assisted Gravity Drainage (SAGD) Process at the Underground Test Facility (UTF) in Fort...

.... The SAGD process is described by Butler (2) . In his 1997 paper Batycky (3) compared the actual CSS performance to numerical simulations of SAGD and concluded that the performance parameters for CSS were better in all respects. These parameters included cumulative steam oil ratio (CSOR) and ultimate...

..., the CMG STARS numerical model was used to simulate SAGD counter-current flows and determine sensitivities to different parameters. Introduction The concept of the SAGD process was developed by Butler et. Al 1 . In this concept, two horizontal wells are placed near the bottom of the reservoir...

... Abstract Adequate lifting of produced fluids is an important issue for SAGD producers. It is often necessary to evaluate the natural lift capability of the SAGD process for given producer well design and modify the design if self-flowing capability of the well is a requirement. This paper...

... in an appreciable reduction of drawdown at various points away from the lifting end of the horizontal section. sagd process injector recovery process enhanced recovery recovery performance oil recovery sweep efficiency investigation productivity pressure drop reservoir susceptible drilling...

... Abstract The application of the steam assisted gravity drainage (SAGD) process using insulated concentric coiled tubing (ICCT ™) as the steam injection string, is experiencing increased popularity for the production of heavy oil. The thermal and fluid mechanic performance of the tubing...

..., porosity, and high temperature residual oil saturation. The use of high qualitysteam gave a better steam oil ratio than lower quality steam, consistent withthe concept that only the latent heat of the steam contributes to oil recoveryin the SAGD process. In all sensitivity runs, the ultimate sweep...

... Abstract This paper presents a simulation study of a steam assisted gravity drainage(SAGD) process applied to the Hanging stone tar sands reservoir. Two pairs of500 m long horizontal wells installed from the surface are considered. The study was conducted to forecast recovery performance...
