Examination of Core and Formation Fluids

STC initiates and supervises laboratory studies of the rock extracted from the well (core) and formation fluids collected at Gazprom Neft oil fields. STC is the single center of accountability and competence with regard to these activities at Gazprom Neft Group.

Examination of Core and Formation Fluids

Core and formation fluids analysis data plays a fundamental role in building digital models of oil and gas reservoirs. A series of tests help select the best method for oil recovery stimulation. STC studies almost 3,000 meters of core and up to 500 samples of formation fluids in its laboratories every year. Test results make the foundation for a reliable estimate of petroleum reserves and help eliminate subsurface uncertainties, confirm formation geology and reduce license risks.

Study and development of new assets helps accumulate extra information and expand technical competences pertaining to the development of non-conventional and hard-to-recover reserves.

By now, STC has developed and tried out a number of unique examination methods for development of hard-to-recover reserves. The Center is working on enhancing oil recovery from salinated reservoirs, testing chemical and thermal techniques of extraction of high viscosity index oil and conducts a number of studies for enhancing the efficiency of drilling, fracturing, and production from low permeability reservoirs. All of these projects are carried out by experts in core and formation fluids exploration.

STC is extensively developing the technologies for modeling formation fluid properties. Existing methods enable precision forecasting of oil properties in the course of field development and help select the best production techniques. After quality estimation, the results of laboratory studies are duly documented and incorporated in corresponding Gazprom Neft databases, which were also developed by STC.
