Increasing the efficiency of extraction of residual reserves of hydrogen sulfide-containing deposits of the Uchkyr gas condensate field

Abstract

This paper examines the low-sulfur gas deposit GKF Uchkyr, which has been preserved for an extended period due to the absence of sulfur removal facilities. The findings regarding the reasons for surpassing or falling behind the actual and projected development indicators are outlined. Additionally, the results of geological and geophysical studies, along with the factors contributing to the insufficient volume of research, are presented. To organize control over the development of a gas field, the correct choice of parameters characterizing the state of the deposit during its development is important. In this case, must be observed conditions that ensure systematic monitoring of changes in selected parameters and assessment of measurement error. These parameters are: reservoir pressure in the gas and aquifer parts of the deposit, gas saturation coefficient of the developed formation, ion-salt composition of the water produced by gas wells. Considering the information above, recommendations are provided to facilitate timely monitoring of changes in technological development indicators and to enhance the efficient extraction of hydrocarbons from the productive horizons of the GKF Uchkyr deposit.
