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;
