The innovative technology for constructing horizontal wells of the optimized two-column design (excluding the third column – a shank of small diameter) is introduced. Geonavigation drilling systems with the continuous work resource (hundreds of hours) allow to drill wells under production casing in one case, in combination with the oil-based mud, ensuring the stability of the trunk, open the oil reservoir by extended horizontal stem, increasing the length of the well. We formulated the task of experimental-industrial tests, described structure of interaction of personnel and the separation of powers post geosupervising. The advantages of hardware-software complex of geosupervision on the basis of digital station "Kedr" are listed. The results of pilot tests are given. For the first time in the oil and gas industry integration of drilling supervision with geological and technological control was implemented on the basis of a digital station at 5 wells of the Vatinskoye field.
Integration of the drilling supervision post with the geotechnical survey party ensured control of compliance of the performed technological operations with the planned ones, reduction of the time of formation of the current and reporting documentation with the release of the supervisor's time for more responsible and highly qualified work, prompt provision of objective information on technological operations to Slavneft-Megionneftegas JSC with the definition of the structure of non-productive time. The digital station of geotechnical survey allowed to reequip modules of remote interactive and production training of the educational and production ground functioning on the basis of Gubkin University, Research and Development Center for Gas and Oil Technologies and Slavneft-Megionneftegas JSC since 2009. Now training of specialists, including masters, researchers and professors of the Gubkin University are performed on innovative digital technology and a new profession of Geosuperviser.
