Abstract: An apparatus for use in fracturing wells includes a body defining and coupled to a wellhead of a well extending through a subsurface formation with the flow path being in communication with a wellbore of the well. The apparatus includes a flow meter in communication with the flow path and configured to measure a flow attribute of fluid from the wellbore along the flow path. The apparatus further includes a computing device communicatively coupled to the flow meter. The computing device is operable to receive a flow attribute measurement from the flow meter and to transmit an indicator in response to determining that the flow attribute measurement indicates interaction of a fracture in the subsurface formation with the well.

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.

Abstract: Systems and methods of hydraulically fracturing subterranean formations include modifying a completion operation parameter for hydraulic fracturing a target well, the target well extending through a subterranean formation and a fracture extending from the target well as a result of the hydraulic fracturing. The modification to the completion operation is responsive to detection of a response of a monitor well extending through the subterranean formation, where the response of the monitor well resulting from interactions between the monitor well and the fracture extending from the target well.

Abstract: Systems and methods for fracturing operations include initiating pumping of a fracturing fluid into a target well according to one or more fracturing operation parameters, the target well extending through a subterranean formation. Subsequent to initiating pumping of the fracturing fluid into the target well, a response of a monitor well extending through the subterranean formation is detected, the monitor well including a sealed monitoring portion. The sealed monitoring portion is substantially filled with a liquid such that the response results from interactions between the sealed monitoring portion and a fracture extending from the target well. The method further includes modifying at least one of the one or more fracturing operation parameters in response to detecting the response of the monitor well.
