Investigation of gas flow hindrance due to fracturing fluid leakoff in low permeability sandstones

Hydraulic fracturing has become a necessary practice in order to attain economical gas flow rates from low permeability formations. During and immediately following the creation of a fracture, high injection pressures cause fracturing fluid to leak off into the adjacent matrix. This work focuses on the impact of fracturing fluid leak off on gas flow through tight formations as a function of leakoff volume and shut-in time. It was observed that...
