System For Inhibiting Flow Of Fracturing Fluid In An Offset Wellbore

摘要

Processes and systems for inhibiting the flow of fracturing fluid through one or more subterranean wells offset from the subterranean well being fractured. A fracturing fluid is injected under pressure via a first well penetrating and in fluid communication with a subterranean region of interest so as to fracture the subterranean region. A second fluid is positioned within one or more second subterranean wells penetrating and in fluid communication with the subterranean region. Each second well is equipped with a standing valve that is seated by the second fluid in each second well. The pressure of the second fluid may be monitored and the pressure applied to the second fluid at the surface may be increased upon determining an increase in pressure during the monitoring step.
