Complex approach to accounting features of the geological structure in the analysis of the level positions of the fluid contacts in carbonate deposits

The question of reliability of determination of the level positions of the fluid contacts sharply raises during the development of oil and gas deposits, confined to carbonate reservoirs. An approach of separation a single deposit into zones with different levels of GOC, based on a detailed examination of the geological structure of the studied sediments, is described on an example of the Eastern section of the Orenburg oil and gas condensate field.
Materials and methods
Analysis of the geological structure of the deposit, the analysis of the provisions of the GOC.
Results
Geological structure and field data of the deposits of Artinsky ONGKM were aligned as a result of this study.
Сonclusions
Determination of fluid contact levels incarbonate sediments is a difficult task to be solved individually for each specific field. Often, as in the above example, clarifying the position of GOC is only possible with the involvement of geological and production data obtained in the process of exploitation.
