SPE conferences in Calgary examine the challenges of finding and producing heavy oil and unconventional hydrocarbons at a time when Canadian producers are feeling exceptional price pressures.
SAGD and Fiber-Optic Distributed Acoustic and Temperature Sensing
Distributed temperature sensing (DTS) is the most common fiber-optic measurement used for steam-assisted-gravity-drainage reservoir monitoring.
Quadlateral Success Story in a Heavy-Oil Reservoir
This paper documents the success story of the first quadlateral completion for an Alaskan operator by use of stacked, rotatable, Technical Advancement for Multilaterals Level-3 junction systems.
Chemical EOR for Heavy Oil: The Canadian Experience
Chemical enhanced-oil-recovery methods such as polymer and alkaline/surfactant/polymer (ASP) flooding are generally not considered suitable for oil viscosities greater than 100 or 200 cp.
Solvent-Enhanced Steamdrive: Experiences From the First Field Pilot
The addition of a hydrocarbon condensate to steam operations in heavy-oil and bitumen reservoirs has emerged as a potential technology to improve not only oil recovery but also energy efficiency.
Pilot Tests of New Enhanced-Oil-Recovery Technologies for Heavy-Oil Reservoirs
Thermal steam stimulation is considered the most effective of current methods for heavy-oil production. However, the method has problems with low coverage by steam injection and decreased efficiency.
To sustain the current level of heavy-oil production, which comprises roughly 12–15% of total production, process efficiency must be enhanced to control costs.
