Paper presented at the Annual Technical Meeting, June 13–17, 1999
Paper Number: PETSOC-99-04
... The figures and table mentioned in this paper are not available in thispdf file. Abstract The performance of horizontal and vertical wells in 12 Canadian oil pools wasreviewed to determine the likely range of ultimate recovery for individualwells. These pools were dissimilar in terms of their...

.... Floods were also carried out in unconsolidated cores using combinations of an alkali, surfactant and a polymer. Individual slugs were injected sequentially in some of the experiments, while the three components were mixed and injected as a single slug in other experiments. Oil recoveries in the two cases...

... Abstract For predicting the performance of water injection in naturally fractured reservoirs, scale-up of the recovery data from immersing an oil-saturated core into water is commonly used. Oil recovery from some of the naturally fractured reservoirs of the North Sea has been better than what...

... that could include "wormholes ∼, dilated zones, or possibly cavities. As well, produced oil in the form of an oil continuous foam resembling chocolate mousse, suggests a foamy solution gas drive occurs in-situ. This leads to anomalously high oil productivity and recovery because free gas stays...

... area in detail one last time. The final result of the exhaustive work, which included core floods, geological review, a 3D simulation, facilities and production optimization review and a reservoir depletion plan, was a large scale waterflood on a depleted field. It is expected that the recovery factor...

... Columbia. Recovery factor is typically low from this type of reservoir due to water production. The problem is frequently attributed to coning, but coning may actually play a minor role. In fact, the gas/water contact in the fracture system may be relatively flat. Initial gas recovery comprises gas...

... The challenge in developing this resource is the difficulty in recovering these highly viscous substances. Thermal recovery has become an accepted method with steam-based recovery drawing much attention. Steam-based recovery methods involve the injection of steam into the reservoir to heat up the...
