Abstract

Summary

Drilling of offshore oil and gas wells remains one of the most important activities of the Russian oil and gas industry in the coming years. The issue of geological exploration and the profitability of the development of offshore fields is still acute. The D33 field is located on the shelf of the Baltic Sea within the boundaries of the Baltic license area. The depth of the sea within the field varies from 60 to 80 m. The purpose of the work is to increase the efficiency of drilling wells and the profitability of the development of offshore fields by optimizing the design of double-barrel wells. Several schemes of drilling of the D33 field with the reconstruction of the well trajectories are proposed. Technical and economic calculations were performed, which resulted in optimization of the design of double-barrel wells at the D33 offshore field. The cost of well construction was estimated according to the basic and optimized version, the results showed that the savings in the construction of a well according to the optimized version will be 5.5%.
