FIELD: oil and gas industry.
SUBSTANCE: in the method implementation, a bottom-hole pressure sensor is installed in the intertubular well space, the bottomhole pressure is monitored under full mud absorption conditions. By increasing the bottomhole pressure by more than 0.5 MPa, the event is set of gas outlet start from the formation into the horizontal bore.
EFFECT: reduced time spent in gas ingressed liquidation, increased safety.
