Methodology for estimating the resource potential of the gas-saturated part of oil and gas condensate and gas condensate fields with due regard for the reserves of matrix oil liquid hydrocarbons based on reservoir thermodynamics (the case of Vuktyl oil and gas condensate field)

Abstract

The article describes the developed methodology for estimating the resource potential of the gas-saturated part of oil and gas condensate and gas condensate fields based on reservoir thermodynamics. This methodology allows to estimate the amount of matrix oil liquid hydrocarbons of the gas part of the field in the absence of direct measurings data for residual water-oil saturation by the extraction-distillation method. The methodology was tested on the example of the Vuktyl oil and gas condensate field. Keywords: carbonate source rocks; gas-saturated part of field; liquid hydrocarbons; matrix oil; reserves; thermodynamic equilibrium.
