The application of the PRMS-SPE standard to geo reserves of oil and gas in Ukraine

The PRMS-SPE is one of the leading international systems for the assessment of hydrocarbon reserves and resources, according to which their categories and classes are distinguished by the degree of study of deposits (reliability), the expected economic effect of their development and the state of existing wells. The calculation of hydrocarbon reserves of the gas field according to the PRMS-SPE criteria has been performed and a comparison of the results with the requirements of the Classification of Mineral Reserves and Resources of the State Subsoil Fund has been performed. It is established that the calculated volumes of hydrocarbons are to a certain extent comparable in size, but are redistributed among themselves by different groups and categories, and reserves/resource reporting for these two standards is fundamentally different, as determined by the differences in approaches to categorization and establishing the boundaries for which the inventory is calculate d.
