Buried Reefs Investigation by Gravity Data

The analysis of gravity anomalies (scale 1:25 000) in researched site was carried out with the purpose of revealing and mapping of oil and gas perspective objects in a difference sedimentations. As is known, buried reefs are shown in gravitational fields by local anomalies of four types: 1) local maxima; 2) anomalies such as "sombrero"; 3) negative anomalies with an appreciable maximum in middle; 4) negative. There are anomalies such as "a gravitational step" less often.
