A relationship has been established in the laboratory between rate of water injection into a simulated fracture- matrix type reservoir model and rate of imbibition. In a series of experiments involving linear countercurrent flow, it was discovered that the higher the water injection rate, the higher the imbibition rate and the greater the indicated ultimate oil recovery. Repeated runs, made using one side of the matrix block and then the opposite side, indicate that the water injection rate (same time duration): imbibition rate correlation is well defined. Two additional factors that dictate the nature of the injection rate-imbibition response are temperature and the condition of the sand face exposed to imbibition. The result of the experimental work suggest that, under proper conditions, increased water injection rates may lead to higher production rates and oil recoveries in reservoirs having fracture-matrix type porosity.
