Abstract
Systems and methods for controlling fracturing operations include monitoring pressure within a monitor well poroelastically couplable to an active well. In response to pressure changes observed in the monitor well, operational parameters of the fracturing operation are modified to, among other things, encourage or inhibit fracture initiation and propagation. For example, modifications to properties of the fracturing fluid, modification to pumping parameters, rate cycling, and diversion operations may each be undertaken in response to observed pressure changes within the monitor well. Single-well applications are also provided in which pressure measurements are obtained from an isolated section of a well poroelastically couplable to an uphole section of the same well. The pressure measurements are subsequently used to control fracturing operations of the uphole section.
