PROSPECTS OF DEEP HORIZONS OF THE NOVOPORTOVSKOYE FIELD BASED ON GRAVITY FIELD TOMOGRAPHY

The results of gravity field tomography by the author’s method imply that the Novy Port oil and gas field in south of the Yamal Peninsula was not fully explored. The tomographic model shows larger anomalies in the top and the upper part of the Paleozoic basement stretching far beyond the field outlines, underlying the already discovered Cretaceous and Jurassic pools. The hydrocarbon content of the anomalies was proved by inflows from prospecting wells tapped into the anomalies. Dry reservoir prevails in wells beyond the anomalies. New large pools in the top and the upper part of the Paleozoic basement can considerably increase the field resources.

Key words: gravity field, tomography, 3D model, anomaly, Paleozoic basement, Novy Port field, Yamal.
