Claim 0:
1. A method of monitoring fracturing operations comprising:
obtaining a measurement of a flow attribute for fluid exiting a monitor wellbore of a monitor well, wherein the monitor well is in a subsurface formation, and wherein the measurement of the flow attribute is measured during a fracturing operation conducted on a target well in the subsurface formation;
transmitting an indicator in response to the flow attribute indicating an interaction of a fracture extending from the target well with the monitor well; and
regulating pressure within the monitor well during the fracturing operation using a pressure control valve, wherein the pressure control valve is disposed along a flow path extending from the monitor wellbore, and wherein obtaining the measurement of the flow attribute includes obtaining a flow meter measurement from a flow meter disposed downstream of the pressure control valve,
wherein, while pressure within the monitor well is below a predetermined pressure, the monitor well is sealed.
