Abstract
At present, Riphean deposits represent one of thepromising exploration targets, which are expected toensure sizeable reserves additions to meet throughput capacitiesof the ESPO oil pipeline and the Power of Siberia gas pipeline. Using three regional seismic profiles Batolit,Kezhma - Patom trough, Svetlaya - Khoshonskaya wells, we examined the mode of occurrence of Riphean deposits inthe zones of their pinch-out. It was shown that, by analogy with the Yurubchenskoe and Kuyumbinskoe fields,the subcrop of the Riphean carbonate deposits beneath the erosional surface may have been favorable forthe deposition of good quality reservoir rocks. The intra-Riphean deposits were shown to have high oil andgas potential. At the present stage of investigation, the priority areas have been delineated for inclusion inGazprom’s exploration and licensing program forthe near and medium term.
