Publication number: 20190063186Abstract: A method is provided to provide fractures in a subterranean formation that utilizes set of first wire line controllable valves (108) to open communication between the inside of a casing (107) and an outside of a casing that has been cemented into a wellbore (101). A wire line controllable valve associated with each of the first valves isolates the inside of the casing downstream of the first valve. The two valves are operated by a wire line actuator. After each successive fracture is formed, the wire line actuator is moved past the next set of valve, changing their positions, and then the next fracture is formed. The valve isolating the downstream portions of the casing are either opened, milled out, or made of degradable material after the operation is complete to enable production from the formation through the fractures into the well bore.Type: ApplicationFiled: March 13, 2017Publication date: February 28, 2019Inventors: Ernesto Rafael FONSECA OCAMPOS, Joddie Joseph CARLILE, Benjamin MOWAD
