Fluid Communication Associated with Hydraulic Fracturing

hydraulic fracturing operations has been a relatively rare occurrence One source (King, SPE 152596, 2012) suggests that in a highly developed area like the Barnett Shale, fracture communication between wells occurs about 10% of the time and that fracture to wellbore communication may occur once every ten thousand hydraulic fracturing events...
