The article examines the experience of drilling directional wells in Turkmenistan, using the latest advanced technologies, in order to increase the extraction of gas and oil from productive horizons in hard-to-reach coastal zones of the coastal waters of the Caspian Sea. One of the priority tasks being solved today by the oil and gas industry of Turkmenistan to increase oil production volumes is the comprehensive modernization of production, the widespread introduction of new technologies and highly efficient equipment. The relevance lies in the application of innovative drilling methods for efficient oil production from hard-to-reach horizons, which is becoming a strategic necessity in the context of the development of the oil industry in the country. The purpose of this study was to analyse the effectiveness of the simultaneous separate operation method in the context of hydrocarbon production in one of the fields of Turkmenistan. The use of the innovative technologies allows to increase the production potential, both by extracting hard-to-reach oil from long-exploited fields, and by putting deep-lying oil horizons into development. Currently, the oil industry of Turkmenistan is facing the issue of involving in the active development hard-to-recover oil reserves, the bulk of which is located in low-permeability reservoirs. The results of the study indicated that the introduction of advanced technologies and equipment in the process of well drilling and completingt in Turkmenistan had a profound impact on oil production. It has led not only to increased efficiency and reduced well construction time, but also increased oil production. This work results can be used to accelerate the development of fields in difficult-to-develop shallow waters and reduce costs during their drilling, as well as to increase oil produced, in order to develop the field in an accelerated manner, without sacrificing oil recovery coefficient.
