Geological Modeling of Complex Traps of Oil and Evaluation of Prospects for Tight Reservoirs Bobrikovian

Currently, oil and gas industry is increasingly focusing on the development of unconventional hydrocarbon accumulations. Today there are questions to involve the development of a significant number of accumulations of oil and gas reserves that were previously considered uneconomic. So, the development of oil deposits, confined to bb-rd age sandstone reservoirs in one of the fields of the Samara region, showed excess amounts of cumulative production compared with the calculated reserves. Refinement of geological model based on the analysis and comparison of the data of drilling, seismic surveys , studies and testing core collectors suggesting that the source of unaccounted oil reserves may be part of the roof bb sand in the dome of raising with lower (below conditional values) data collector properties according to GIS.
