The article highlights the activities of LUKOIL PJSC in the area of research, adaptation and testing of new technologies as part of the implementation of the Pilot Operation Program in the Company. Statistical data on the pilot operation performance and on the transition of the technologies to the commercial operation stage is provided. The history of enhancing the hydraulic fracturing technologies, construction of multibranch wells (multilateral and multihole ones), drilling of slim wells is highlighted as examples of development of the innovative directions on the “from simple to complicated” basis. As part of development of the hydraulic fracturing area, information is provided regarding the evolution of applicable hydraulic fracturing technologies from formation injection operations (up to 10 t of propping agent) to large-scale hydraulic fracturing (100 t and more) and, further, to multistage hydraulic fracturing technologies for horizontal wells. The data on the efficiency of multistage hydraulic fracturing at LUKOIL PJSC fields is provided. The development of multilateral well construction technologies in the Company is represented from the drilling of first multilateral wells with double completion and further to the construction of multihole wells with TAML-5 complexity degree at the offshore fields. Drilling of slim wells obtained its development and distribution across LUKOIL PJSC primarily due to its economic viability for the conditions of the mature fields operating at the advanced development stages. Starting from year 2010, the slim well drilling technologies have evolved from pilot operations to the level of engineering solutions for field development project design documentation. Besides, in 2017, a first multilateral slim well was successfully drilled at the Osinsky field, and a sidetracking technology for slim wells was developed.
