Annotation:
During the period of reserves joint development from the oil rim or the gas cap of the oil or gas well according to the purpose, in accordance with the current Development Rules, the subsoil user should keep separate records of the produced gas from the gas cap (GC) and dissolved petroleum gas. Gas condensate production volumes also require separate accounting, not only to maintain a balance of minerals, but also to plan effective measures for the hydrocarbons extraction and a feasibility study justification of medium and long-term field development plans.
The article considers the application of the algorithm developed by specialists of LUKOIL-Engineering LLC, which allows, based on the field data, to analytically separate the produced oil, condensate, gas from the gas cap and dissolved gas.
The results of the calculations are presented in comparison with the existing approach to the separation of hydrocarbons; targeted examples by wells are presented, reflecting the essence of the proposed refinements in the separation of liquid hydrocarbons and gas. The results of the separation and the main reasons for the changes are grouped to make easier the analysis and the data compilation.
