Clarification indicators of development of Vilhivskyi’s condensate field by fal-ling reservoir pressure

Abstract

The method of reservoir pressure drop as one of the main methods used to address the additional exploration of gas condensate fields (on the example of Vilhivskyi GCM) has been considered. Appropriate calculations were made using this method, which specified the development indicators for the period from 2013 to 2018. The current state of Vilhivskyi gas condensate field deposits development has been analyzed and options for development have been justified. There are I, II, III and IV operating facilities in Vilhivskyi field in industrial design. As of 01.10.2013, on the eastern vault I the object is developed by one borehole, which is currently in the overhaul, the second facility - by the two wells (w. 57, 61), the third object - by one hole (St. 60), the fourth object - by seven wells (w. 51, 52, 53, 54, 55, 58, 84). On the western vault I object was worked out by well 26, which was closed in 1993 due to flooding, II object is being developed by one borehole (w. 9), the third object - by one borehole (w. 81), IV object – by nine wells (w. 59, 62, 63, 64, 65, 70, 80, 82, 83).
