... through the water fingers and bypass significant volumes of continuous oil. It has been shown in other works that alkali and/or surfactant injection can lead to improved heavy oil recovery compared to waterflooding, but researchers have proposed different reasons for this response. This work summarizes...

... Abstract A statistical study of 166 western Canadian waterfloods recovering heavy and medium gravity oils revealed new findings about best operating practices for heavy oil waterflooding. In classical light oil waterflooding, operators are advised to start waterflooding early and maintain...

... Abstract This work details the results of ambient temperature waterfloods in unconsolidated sand containing heavy oil (11°API and viscosity of 11,500 mPa⋅s at 23°C). Experiments are performed at rates ranging from 0.4 – 0.02 m/day, in sand with permeability of under 1 D to 9 D. By varying both...

..., they were at saturation pressure at the initial conditions. Some of these reservoirs have been subjected to waterflooding after a period of primary production. Therefore, in addition to the mechanical condition of the well, multiphase flow and fluid property variation make the traditional pressure analysis...

... Abstract Analytical techniques for prediction of waterfloods using homogeneous models are non-representative of behaviors observed for actual reservoirs. We have noted, however, that a scrutiny of such deviations can lead to estimation techniques for characterization of permeability contrast...

... Abstract In West Central Saskatchewan the Mississippian/Devonian middle Bakken Formation was deposited as NE-SW trending sand ridges, capable of producing heavy oil. In the Court field, the middle Bakken sand pool has been operated as a heavy oil waterflood for over 15 years with significant...

... Abstract A sound geological model, a consistent geocellular model, and flow simulation are all critical components to successful optimization of a heavy oil waterflood project. Despite the availability of a sound geologic model, high quality seismic and abundant core, log, and production data...
