LIVE BOTTOM HOLE PRESSURE FOR PERFORATION/FRACTURING OPERATIONS |
摘要 |
A method of determining when to stop pumping proppant during hydraulic fracturing in a wellbore is described. By accurately detecting tip screen-ou t with a bottom hole pressure gauge mounted to a perforating gun, the optimal amount of proppant can be supplied to a fracture while avoiding the risks associated with wellbore screen-out.
