FIELD: oil and gas industry.
SUBSTANCE: method includes operations for providing the coiled tubing string with cable along its entire length, providing the coiled tubing string ends with controlled anchor with a rupture element or coupling with standardised release force, a connecting coiled tubing string with anchor, running the coiled tubing string with the cable into the well to a target elevation, actuation of anchor, pulling the coiled tubing string from the well with breakage of said element or disconnection of said coupling. In this case, the well remains equipped with a geophysical cable, and the coiled tubing string can be used for other purposes. Due to disruption of anchor when the cable is tensioned, it is possible to extract it at the end of examination or monitoring.
EFFECT: possibility to equip horizontal well with geophysical cable.
