FIELD: oil and gas industry.
SUBSTANCE: two-dimensional survey of acoustic emission is performed in oil region. As per amplitude, energy and/or power of acoustic emission there detected are abnormal zones by identifying them with weak tectonic disturbance. As per anomalies of acoustic emission there detected are breaks in which there are covers in the form of the formations not disturbed at the present time. As per anomalies of acoustic emission or on resonant frequencies of breaks there detected are breaks in which there are active covers. Well location places are chosen in the zones of the breaks where there are covers.
EFFECT: reducing drilling volumes.
