Evaluation of the Steam-Injection Process in Light-Oil reservoirs

摘要

Feasibility of steam injection for three light-oil reservoirs in dif- ferent geologic settings has been evaluated. The setting studied were a waterflooded deltaic sandstone, a waterflooded vuggy dolomite, and a delatic sandstone structural trap with a gas cap. Optimization of steam injection to take advantage of individual Reservoir characteristics is demonstrated. Results show that light-oil steamfloods can be designed to take Advantage of pot-secondary oil-saturation distribution. The result- Ing project may be carried out in a considerably different fashion From that of conventional heavy-oil steamfloods.
