Complex processing geophysical survey and selection of methods for detailing the geological structure of mega-reservoirs (Hayan block, of the Palmyride fold belt) by V. L. Schuster, O. V. Tyukavkina, I. Kartal

“…The processed materials made it possible to select the most effective GWD combination for identifying the boundaries and fringe zones of sediments in the Kurrachine-Dolomite formation, considered as a mega reservoir, and to identify priority development objects similar in geological structure and reservoir properties.Conclusion. The proposed method for processing field geophysical materials (construction of correlation matrices and statistical processing of geological and field data) can be used in selecting an optimal combination of GWD for establishing the reservoir boundaries of the Kurrachine-Dolomite formation, quantifying the reservoir properties, and increasing the efficiency of the Jihar field development (mega reservoir of the Hayan block).…”
