Study on Matrix, its Role in Controlling Oil and Water Movement

Jiateng Lv



This presentation shows that reduced Fracture Permeability can lead to acceleration of oil movement in matrix, leading to increased oil recovery efficiency. Water wet tendency reservoirs provide best recovery performance, and oil wet reservoirs show worse recovery performance. The more water wet reservoir tends to be, the better production result will be. Increased Rock in Fracture (%) may slightly increase water movement speed but decrease a flow rate of oil. It can lead to decreased thermal conductivity. Reduced thermal properties for fluids have a less effect on water and oil movement in a reservoir; however, they decrease thermal conductivity in the reservoir.
