Methodological approach to the resource base efficiency monitoring in oil fields development

Abstract

The article discusses the issue of resource base management in a complex structure of residual reserves. To increase the efficiency of the reserves development, constant monitoring of their distribution is necessary - how much they are involved, is there any potential for additional involvement, how efficient are the areas already involved in development. The paper proposes a methodological approach to the residual reserves control process organization, which allows planning and adjusting the program of reserves development. This is of particular relevance for companies that develop assets in the late stages of development, which do not have the ability to indiscriminate drilling. On the example of one of the enterprises developing assets in the Volga-Ural oil and gas province, the structuring of residual reserves was carried out, on the basis of which a strategy for increasing the reserves involvement in development was formed. To analyze the efficiency of reserves recovery in the involved areas, a reserve utilization factor based on the displacement forecast is proposed. Its implementation made it possible to identify problem areas, on the example of one of which a highly effective program for drilling horizontal wells was subsequently implemented.
