... of the steam zone. The amount of heat accumulated in the reservoir, after 0.7 PV of steam had been injected and 1.0 PV of shut-in time, was approximately 47% of the heat injected prior to shut-in. Runs 9, 11 and 13 were completed to study the effect of steamflooding reservoirs having a 20% bottom-water layer...

... wells. INTROI)UCTION Due to the poor injectivity in most oil sand deposits, it is believed that the formation must be fractured to allow steam injection at a reasonably high rate. Initially, the steam zone surrounding the fracture is probably elliptical in shape. As the steam injection continues...

... of steam, some information is Sacrificed to gain steam information. The paper describes the principles and algorithms for distinguishing live steam zones from hot water zones at observation wells using temperature gradients and independent of pressure information. If sufficient data exists, the analysis...

...-steam ratio, steam zone volume, temperature distribution, and residual oil saturation in steam, hot water, and cold water zones were examined. Results showed there is an optimum injection rate to efficiently displace the crude oil to a low residual saturation while reducing the heat losses from...
