Abstract
The article objectives are developing hard-to-recover reservoirs and how to maximize oil production by formulating effective solutions for putting hard-to-recover reserves. US2is planned to be put into development in 2022 and contains 52% of the initial reserves of the entire field. US2reservoir complicated by low permeability 0.6 mD, saturated intervals are 9.8 m. The main method of developing hard-to-recover reserves in Western Siberia fields is horizontal drilling with multi-stage hydraulic fracturing. As a matter of course, well designs were analyzed with different lengths of horizontal shaft and with a different number of hydraulic fracturing ports. Calculations of starting flow rates and production profiles for various well options for a typical well have been performed. The optimal solution was evaluated using the complex parameter NPV and cumulative production.
