THE SOUTH-KIRI FIELD – GAS PRODUCTION PROSPECTIVE BASE IN THE FAR EAST OF RUSSIA
A 3D seismic survey completed within a basement high in the Gazprom’s Kiri license block on the Sakhalin shelf permitted mapping part of a large non-structural trap in the Dagi top. Analysis of a seismic amplitude anomaly was the basis to predict the presence of a large gas deposit formed on the structure flank and bounded by lithologic replacement of the reservoir. A first prospecting well drilled there confirmed the seismic interpretation and discovered a large gas field on the Sakhalin shelf.
