FIELD: rational location of prospecting and following operating holes while searching for oil and gas. SUBSTANCE: method is intended for more accurate determination of boundaries of carbon depositions and detection of most productive zones. Materials of drilling, of surface and borehole seismic studies, of paleogeomorphological analysis are used, lithofascie of paleoshelf are exposed, boundaries of their linearization along laterals and summary thicknesses of permeable differences of rocks contained in these lithofascie are determined. Prospecting and operating holes are positioned within outlines of agrillization boundaries in zones with maximal summary thicknesses of mentioned rocks. EFFECT: more accurate determination of boundaries of carbon deposits.
