At a late stage of development, with deterioration in the structure of reserves, the use of advanced technologies and development principles helps to maintain the level of oil production and fully develop reserves. Technologies such as drilling horizontal wells and hydraulic fracturing are undoubtedly technologies with a wide range of applicability at various sites and in different mining conditions. It is especially important to use development systems with horizontal wells in fields with high geological heterogeneity, stratification, presence of numerous replacement zones of reservoirs, zones of wedging, sections of thin reservoirs. Such complex objects include terrigenous sediments of the Bobrikovian horizon of deposits No. 2,3,33 and carbonate sediments of the Kizelian horizon of deposits No 281, 292 of the Romashkino field. Horizontal technologies for the purpose of involving reservoirs of the Bobrikovian horizon have been actively used since 2015. More than 40 wells with an average increase of more than 15 tons per day have been drilled, this is one of the main factors of production growth in the upper horizons. In 2016, a horizontal well No. 3745G with an input rate of 10.9 tons per day was built on the Kizelian horizon, which is 7 times higher than the production rate of vertical wells. Main results and achievements of Oil and Gas Production Department «Aznakayevskneft» Tatneft PJSC in the field of horizontal drilling and hydraulic fracturing are considered. According to the strategy of Oil and Gas Production Department, it is projected to drill 55-60 horizontal wells and carry out 20-30 fracturing processes in horizontal wells every year until 2025.
