... Abstract Caprock integrity in steam-assisted gravity drainage (SAGD) has been evaluated by various researchers. However, most of these caprock integrity studies assume that the caprock is not fractured, which is not a valid assumption in most cases. This paper provides a comprehensive analysis...

... Summary Steam-assisted gravity drainage (SAGD) is the preferred thermal recovery method used to produce bitumen from Athabasca deposits in Alberta, Canada. SAGD operation is experiencing five stages: ramp-up, initial plateau, full-length plateau, wind-down and coalescence. The physics...

... Abstract Effective Steam Assisted Gravity Drainage (SAGD) operation relies on subcool management to reduce the risk of steam breakthrough. Monitoring of several parameters is performed to assure uniform development of steam chamber and heating of reservoir. This paper discusses the application...

... Summary Over the last decade, steam assisted gravity drainage (SAGD) process has been successfully commercialized in Alberta and Saskatchewan thermal projects. Remediation of slotted liner wells in cases of erosion, or high gas/steam production later in life requires a different basis of design...

... Abstract Steam-assisted gravity drainage (SAGD) recovery process is strongly impacted by the spatial distributions of heterogeneous shale barriers. Though detailed compositional flow simulators are available for SAGD recovery performance evaluation, the simulation process is usually quite...

... Abstract Air injection into mature SAGD chambers is a promising method to sustain steam chamber pressures while reducing steam-to-oil-ratios (SOR) and increasing oil production in SAGD late life. The feasibility of attaining and sustaining a high temperature combustion front when injecting air...

... Abstract Dispersion of a solvent into heavy oil and bitumen in porous media has special significance in the context of solvent-based as well as solvent-aided versions of SAGD and CSS recovery processes. While solvent is injected with steam, the mixture condensation temperature changes based...

... Abstract This paper proposes a new criterion to estimate the impact of lean zones on thermal or thermal-solvent processes, such as SAGD, SA-SAGD, or EBRT (Imperial Oil's "Enhanced Bitumen Recovery Technology"). The interface stability of the steam/solvent chamber in the lean zone is related...
