METHOD OF MAPPING HYDROCARBON RESERVOIR AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2011 - IPC G01V3/08 G01V3/15

Abstract RU 2428719 C2

FIELD: physics.

SUBSTANCE: method is realised using an electromagnetic field source (1113) which transmits current pulses (81, 82) with sharp edges to an immersed vertical transmitting antenna. The electromagnetic field generated by pulses (81, 82) is measured using at least one receiver (1109) fitted with a vertical receiving antenna (1111) immersed in water during a period of time in which there is no transmission of pulses to a transmitting antenna (1108) by the electromagnetic field source (1113). Distance between the electromagnetic field source (1113) and at least one receiver (1109) is less than the depth of the target object.

EFFECT: high accuracy.
