...Rajan G. Patel; Japan Trivedi; Shahed Rahim; Zukui Li Summary History matching of a steam-assisted-gravity-drainage (SAGD) reservoir requires a large ensemble size for proper uncertainty assessment, which ultimately results in high computational cost. Therefore, it is necessary to reduce the number...

Two SAGD experiments at identical experimental conditions were conducted. The reservoir rock for the first...

... of the overburden zones above in-situ oil-sands mines and for assessment of caprock integrity in steam-assisted-gravity-drainage (SAGD) projects. In general, caprock-integrity assessments include caprock geological studies, in-situ stress determination, constitutive-property characterization, and numerical...

...Karim Ghesmat; Litong Zhao Summary The steam-assisted-gravity-drainage (SAGD) process has been widely used commercially in western Canada for bitumen production. Improving the oil-production rate and reducing the steam/oil ratio (SOR) have been the focus of the industry. In heterogeneous reservoirs...

... such as steam-assisted gravity drainage (SAGD). Moreover, gas production from the gas cap can accentuate the problem even more by further depressurization of the gas zone. Following a September 2003 ruling by the Alberta Energy Regulator (AER), the oil and gas industry in the province of Alberta, Canada, had...

...Leah Miller Guindon The feasibility of using fewer wells in a steam-assisted-gravity-drainage (SAGD) project during solvent coinjection was investigated, which resulted in a field test showing that using a wider well spacing with a solvent-aided process (SAP) enhances production and reduces...

... for 100- kHz frequency. Introduction Viscosity is a major obstacle in the recov- ery of bitumen in oil-sand reservoirs. Ther- mal recovery is considered the most ef- fective method for lowering viscosity, and steam-assisted gravity drainage (SAGD) is the most promising thermal recovery tech- nique applied...
