Methodology of capacity calculations Methodology of capacity calculations

HEXUM Natural Gas has determined the technical capacities of UGS as follows.

The technical capacities of Szoreg-1 UGS were calculated, while the results were justified by measurements and simulations.


  • The initial pressure data and porous volume of the reservoir were the basis of determination of working gas capacity. The calculated working gas capacity equivalent gas volume was injected into the UGS and the pressure of the reservoir did not exceed the limit approved by the Mining Authority.

  • The capacity of the injection technology was justified at the end of the injection cycle with full load of compressors.

  • The withdrawal capacity measurement was done by stand alone test of gas processing units and wells. The well tests were completed with simulations. The whole well capacity was audited by Geostock France.
