Systems and methods for controlling fracturing operations using monitor well pressure

A method of fracturing subterranean formations comprising:

• subsequent to initiating pumping of fracturing fluid into a target well extending through a subterranean formation, detecting a pressure response of an internal volume of a sealed monitoring portion of a monitor well extending through the subterranean formation, wherein:
• the pressure response results from interactions between the monitor well and a fracture extending from the target well, the fracture causing a deformation of a casing defining the internal volume of the sealed monitoring portion, the deformation altering the internal volume of the sealed monitoring portion and causing the detectable pressure response of the internal volume,
• the sealed monitoring portion is sealed relative to the subterranean formation to prevent fluid ingress into the sealed monitoring portion and includes the casing of the monitor well, the casing defining the internal volume of the sealed monitoring portion, and
• the internal volume of the sealed monitoring portion is substantially filled with a liquid;
• and
• in response to detecting the pressure response, each of stopping pumping of fracturing fluid into the first target well and initiating pumping of fracturing fluid into a second target well extending through the subterranean formation, the second target well being different than the first target well.

A system for providing a fracturing fluid to a subterranean formation comprising:

• a pump coupleable to a wellhead of a target well extending through a subterranean formation, the pump configured to provide fracturing fluid to the target well according to one or more fracturing operation parameters;
• a pressure transducer adapted to measure pressure within an internal volume of a sealed monitoring portion of a monitor well, the sealed monitoring portion being sealed relative to the subterranean formation to prevent fluid ingress into the sealed monitoring portion and including a casing, the casing defining the internal volume of the sealed monitoring portion;
• and
• a computing device configured to:
• receive pressure measurements from the pressure transducer;
• identify a change in the pressure measurements received from the pressure transducer indicating a pressure response of the internal volume, the pressure change resulting from interactions between the monitor well and a fracture extending from the target well, the fracture causing a deformation of a casing defining the internal volume of the sealed monitoring portion, the deformation altering the internal volume of the sealed monitoring portion and causing the detectable pressure response of the internal volume;
• and
• generate an alert in response to detecting the change in the pressure measurements.
