METHOD OF INTER-WELL TOMOGRAPHY AND SYSTEMS USING A CASING SECTION WITH AT LEAST ONE DATA TRANSMISSION AND RECEPTION DEVICE Russian patent published in 2018 - IPC E21B47/13 G01V3/30 

FIELD: mining.

SUBSTANCE: invention relates to a study of inter-well space. In particular, a cross-borehole tomography method is proposed, comprising casing of a first well bore with a casing having at least one data transmission and reception device, wherein each data transmission and reception device has an adapter communicating with the loop antenna that covers the outside of the casing. Method also includes placement of a current path within the casing that extends from the ground interface to at least one data transmission and reception device. Method also includes provision of a set of one or more antennas in a second well bore. Method also includes obtaining of electromagnetic (EM) measurements for inter-well tomography using at least one data transmission and reception device and a set of one or more antennas, the above-mentioned receipt of measurements including data or energy transfer between at least one data transmission and reception device and a ground interface via a current path.

EFFECT: technical result is to improve the efficiency of inter-well monitoring.
