Claim 6:
7. An apparatus comprising:
a body defining a flow path, wherein, when the body is coupled to a wellhead of a well extending through a subsurface formation, the flow path is in communication with a wellbore of the well;
a flow meter in communication with the flow path, wherein the flow meter is configured to measure a flow attribute of fluid from the wellbore along the flow path;
a computing device communicatively coupled to the flow meter, wherein 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;
a pressure control valve upstream of the flow meter, wherein the pressure control valve is operable to open when pressure within the wellbore is above a pressure setting of the pressure control valve, thereby permitting flow of fluid from the well, and to seal the wellbore when pressure within the wellbore is below the pressure setting; and
a pressure transducer upstream of the pressure control valve to measure pressure within the wellbore.
