FIELD: mining.
SUBSTANCE: method consists in irradiation of rocks by fast neutron flow, radial probing of gas recovery reservoir by multi-probe modification of neutron method and/or complex of different-depth neutron methods and registration of data as well-logging records. Note here that measurement results are compared to reveal temporary cavity from availability on inversion in probe depth readings compared to larger-depth readings describing given gas recovery reservoir.
EFFECT: higher reliability and efficiency of detection.
