Geological Simulation, Estimation Of Reserves, Raw Materials Base Monitoring

Institute experts possess long-term experience of carrying out a range of works in this area for fields with various geological and hydrodynamic conditions and situated in different regions of the country and abroad.

The range of works includes:

  • estimating commercial and recoverable reserves based on 3D geological and hydrodynamic models;
  • developing structured models of oil and gas deposits in terrigenous and carbonate deposits with differential estimation of reserves;
  • supporting prospecting and exploratory drilling;
  • monitoring and optimizing sidetracking;
  • generalizing and analyzing the condition and changes of the resource base of oil companies, regions, and the country.
  • correlating productive strata and identifying lateral variation of collectors and isolating rocks;
  • identifying and grouping localized collector bodies and describing their morphological and genetic features, level of isolation, and possibility of merging with other objects;
  • justifying the quantity and magnitude of estimation targets taking into account the structure and features of the localized bodies and distribution of fluids across the productive strata;
  • carrying out geological 3D modeling of estimation targets based on own and outside geological, geophysical, laboratory, and commercial data;
  • estimating the reserves of oil, gas, and associated components in formats of state and corporate standards;
