... Abstract Gel damage has been identified as the most severe damage effect on gel-fractured well productivity. The reduced effective fracture length and fracture conductivity can significantly decrease the initial production rate and the ultimate recovery, especially for tight reservoirs...

... but not limited to several issues: It can be severely reduced in case of multi-phase flow inside the fracture due to non-Darcy effects when bottomhole flowing pressure is significantly below bubble point pressure. At the other extreme, heavy and viscous formation fluids lead to rapid fracture conductivity...
