... and constrains of the business. The need is to match the recovery processes to the reservoirs. Industry multi-company research programs were focused on processes that were not viable in the new price environment Also target reservoirs were not similar to the vast majority of the fields found...

... efficiently sweep/displace oil. Such impediments could be due to coning, insufficient injectivity/ productivity, heterogeneities, fractures, anisotropies, poorly connected or ‘compartmentalized’ reservoirs, viscous fingering, recovery processes affected by severe gravity over-ride, etc. With the removal...

... Abstract Based on Pujol and Boberg's scaling criteria, a series of experiments on steam-CO 2 injection strategies was conducted in a high temperature, high pressure scaled model to evaluate oil recovery processes for bottom water reservoirs. The scaled model simulated 1/8th of a jive-spot...

... recovery of Canadian heavy and extra-heavy oil has taken place. This has resulted in the development and commercialization of many recovery processes using steam. Current production from active projects is about 18,000",J per day. To cope with the large variation of geological and petrophysical conditions...

... of the casing. It is concluded that a casing, though necessary to control sand production into a horizontal well, could lead 10 lower cumulative oil recovery and lower thermal efficiency for the recovery process. For example. oil recovery and the cumulative oil-steam ratio in the absence of a casing were 49.7...

... Abstract In situ combustion, and its modified forms, continue to be important oil recovery processes. The applicability of in situ combustion to a wide range of reservoirs, and the recent advances, show that this process has unique advantages (and disadvantages). Laboratory studies of in situ...
