Effect of matrix wettability CO2 assisted gas-oil garvity drainage in naturally fractured reservoirs

The wettability behavior of the matrix block is one of the major factors controlling the effectiveness of the employed EOR methods in NFRs. Water injection in NFRs with mixed-wet or effectively oil-wet matrix blocks usually results in low oil recoveries. In this case, gas injection is considered to be an alternative process, where the process...

Dynamic Interactions between Matrix and Fracture in Miscible Solvent Flooding of Fractured Reservoirs

Miscible solvent injection has received increasing attention in recent years as an efficient method to improve oil recovery from fractured reservoirs. Due to the large permeability difference between fracture and matrix, the success of this method depends to large extent on the degree of enhancement of the mass exchange rate between the solvent...
