Integrated marine gravimetric system. Development and operation results

Abstract

The paper discusses a mobile gravimeter Chekan-AM, which is the further development of sea gravimetric systems created by the CSRI Elektropribor in the course of thirty years. The basic designs of the gravity sensor and gyro stabilization system are considered. The results of long-term operation of gravimeters used by Russian and foreign companies for marine geophysical surveys conducted in different areas of the Arctic, Atlantic, Indian and Pacific Oceans are presented. The comparison of the results obtained with the results of seismic survey has shown that gravimetric data offer considerable promise for oil and gas searching on the shelf.
