... Abstract The gravity drainage and oil reinfiltration phenomena that occur in the gas cap zone of naturally fractured reservoirs are studied through single porosity refined grid simulations. A stack of initially oil-saturated matrix blocks in presence of connate water surrounded by gas-saturated...

... Abstract Initially, gravity drainage mechanism in naturally fractured reservoirs was modeled and validated by solving the available analytical equations (e.g. Firoozabadi and Hauge method in 1990). Block to block interaction effect has been included in this model. Then the effects of different...

... processes, either acting as the driving force in processes using horizontal wells or altering displacement patterns during waterflooding, chemical flooding, CO 2 flooding, and other EOR processes. Gravity drainage driven oil production in naturally fractured and other complex reservoirs falls into two...

... Abstract This work examines the well and reservoir performance under both solution gas-drive and gravity drainage in homogeneous systems. Based on synthetic information obtained with a fully implicit black-oil simulator, the influence of different parameters like oil rate, position...

... Abstract Focusing on the Smoerbukk (Smorbukk) fields it is proposed to introduce imbibition capillary pressure by a new method which entails representing Pc analytically starting from the primary drainage curve. Predicted saturation is shown to agree with wireline log data from a Smoerbukk...
