Abstract

Hydraulic fracture is highly important to increase the well productivity of gas condensate reservoirs. This paper studies the effect of fracture damage on the performance of a well. This paper focuses on the fracture face skin damage that might reduce the effectiveness of the fracture. As the fracture length increases, the damage around the fracture that is caused by permeability impairment also increase, so there is an optimum fracture length above which the fracture length is no more effective. This paper presents a comprehensive study on the effect of fracture face damage while hydraulic fracturing in gas condensate reservoirs and relate it with condensate drop out around the fracture. This paper also presents the optimum fracture half length and also emphasize on the importance of the fracture face skin during hydraulic fracture design.
