Monitoring and perforating system and method combining plug and perforation operation with distributed acoustic sensing
A system for treating a plurality of adjacent wells having casing includes a wireline, perforating equipment, and a fiber-optic interrogator. A fiber-optic interrogator is configured to interrogate the at least one optical fiber for distributed acoustic sensing. The wireline deployed in a well with the perforating gun can remain in the well, while an adjacent well is stimulated to produce hydraulic fracture. During the stimulation, the fiber-optic wireline is used for distributed acoustic sensing during the fracture operation of the adjacent well. A zipper fracture operation between adjacent wells can use multiple systems in conjunction with pumping equipment to monitor the fracture operations in real-time and obtain imaging and seismic information of the fracture network.
