Estimation of theoretical production capacity of long-term operated well stock

The paper deals with the issue of the rational use of well stock via the specification of the capacity increase of production in the long-term developed fields. The distribution graph of oil by all wells has been developed based on the statistical processing using a system approach of obtained field data. The hyperbolic nature of obtained distributions indicates the irregularity of the development and operation processes of the fields. The distributions of the total oil and water production by selected output intervals have been developed and analyzed as well. Mathematic models of obtained distribution functions have been specified. The results of studies carried out enable us to estimate the theoretic production capacity of reviewed well stock.
