The Buried Reefs Mapping by Seismic and Gravity Data

The prospects of detection of HC deposits in the Timan-Pechora province contact by reef structures in Ust-Pechora carbonate sediments of Upper Devonian. The interpretation of gravitational anomalies was directed on revealing and mapping of reefs and connected with by them decompactions – potential traps HC. The prospects of the decision were estimated proceeding from results of researches of gravitational fields anomalies above buried reefs structures in various oil content areas. Revealed thus by the numerous researchers of law of display of reefs in gravitational fields testify as to potential opportunities of gravity by searches of buried reefs, and allow to make a choice of techniques of interpretation of a gravitational field.
