... flows convectively away from the injection well and releases its latent heat at or near the edges of the steam depletion chamber. The temperature of the oil sand at the chamber edge rises and consequently the mobility of the bitumen there increases and under the action of gravity, it drains along...

... the injection well bore decreasing oil production. Suspended metal sulfides also stabilize oil-water emulsions preventing effective separation of produced water and oil. Hence souring is highly undesirable from a business and operating point of view, especially when the original facilities were not designed...

... management of these waterflooding processes provides several important challenges. Some of the questions facing engineers and mangers during designing and operating waterflood projects are; the location PETROLEUM SOCIETY 2 and pattern used for injection wells, amount and rate of water injection, and so...

... location of the injection well. For VAPEX#1, the total length of 0.6 meter injection well was slotted. However, for VAPEX#2, the first 0.12 meter near the heel side and the last 0.05 meter near the toe side were not slotted. The reason was, based on previous experiment15 and the analysis of the VAPEX#1...

It is characterized by thick oil layers, high permeability contrast, high oil viscosity and high water salinity. All injection wells were completed...

... of these parameters act in concert in the recovery process. Edmunds and Gittins(4) discussed the concept of steam distribution in SAGD wells and the importance of the pressure drop in the injection liner in defining chamber shape and process performance. The general concept is as follows: injection well pressure...
