Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...

Fracture reservoirs contain most of the oil reserves of the Middle East. Such reservoirs are poorly understood and recovery from fractured reservoirs is typically lower than those from conventional reservoirs. Many efforts have been made to enhance the recovery and production potential of these reservoirs. Fractured reservoirs with high matrix porosity and low matrix permeability need a seconda...

Aim at large scale fine reservoir numerical simulation application research on Shenwei computer, the multilayer two dimension two phase parallel software transplanted successfully and a large scale integral simulation about ten millions nodes were realized in the environment of Shenwei parallel computer. The whole preconditioning alternating Schward and another many improved algorithm, the para...
