Abstract
Many fields in the Surgut oil and gas region are in the late stages of development. However, the assessment of hydrocarbon reserves is not always reliable, and geological and technological measures for oil recovery (GTO) show their effectiveness. This is due to approaches to geological modeling of reservoirs and complicating factors for conducting targeted well interventions (high drilling and depletion of reserves).
In this regard, there is a need for an accurate assessment of hydrocarbon reserves; localization of residual reserves by area and assessment of the success of geological and technical operations, which can be solved using the ranking of facies. The paper demonstrates the assessment of hydrocarbon reserves using the coefficient of layered clay content (χsh); the ranking of facies by oil-saturated thicknesses, porosity and permeability properties, initial oil production rates was carried out; cumulative production per well.
The simulation results showed that the use of the parameter χhl leads to a significant refinement of reserves. The results of facies ranking showed that it is recommended to carry out geological and technical operations in the zones of development of facies of the I-II ranks (facies of the beach, mouth and barrier bars) in the presence of residual reserves in them.
