"RN-Yuganskneftegaz", included in the oil-producing complex "Rosneft" has set an absolute historical record of daily oil production – 198,008 thousand tons. This is the highest indicator for all history of production of the company with 1964, which is more than 800 tons exceeds the previous record set in October 2018.
the Highest result was achieved thanks to the professional work of the staff of the enterprise, introduction of advanced technologies in the process of mining, increasing the resource base, the successful development of tight oil, the commissioning of new production capacities.
"RN-Yuganskneftegaz" introduces advanced technology to engage in active development of hydrocarbon reserves from low-permeability reservoirs, but also uses technology to increase oil recovery in Mature fields. For several years the specialists of our enterprise jointly with the corporate scientific and design complex, the company has developed and tested various completion systems for horizontal wells with conducting a multistage hydraulic fracturing (MHF). After a series of successful pilot tests, the mass horizontal well drilling with multistage fracturing operations on complex manifolds.
New solutions for increasing the length of the horizontal section of the wells 1,500 to 2,000 m and the introduction of a 20-stage hydraulic fracturing allow you to extend the reach of cost-effective drilling in the edge zones of the deposits. For the development of reservoirs with low permeability, the specialists of the enterprise are changing the geometry of a hydraulic fracture using new technologies, use modern geomechanical modeling. While implementing the development system with the introduction of transverse hydraulic fractures, which increases the contact with the cracked layer, increasing the productivity of the well.
In the 2nd quarter of 2019, the company has drilled on Sarovskom field two wells with new technology "Fishbone" with four side holes at different production zones. Zapusknoe well production reached 600 tons/day. In the future we plan to replicate this technology.
All horizontal and multilateral wells are drilled with application of geosteering in real time using developed by the Company innovative software systems and modern methods of logging. This allows precision to get into thin layers of thickness up to three meters in depth to three kilometres.
With the purpose of increase of efficiency of development of deposits carry out a complex of geological and technical measures. Is the recovery well method of sidetracking, shall apply the measures on stimulation of wells, are widely used physico-chemical methods of enhanced oil recovery and measures to control flooding, introduced the system of simultaneous-separate operation.
To intensify production and increase oil recovery factor is applied re-fracturing deviated and horizontal wells and infill drilling, including with use of horizontal wells with multistage fracturing operations.
the New scientific and technical solutions, advanced technology and system design has allowed to significantly expand the resource base and breathe new life into the development of oil deposits "RN-Yuganskneftegaz".
Rosneft pays special attention to innovative activities, defining technological leadership as a key factor of competitiveness on the oil market, that has a direct impact on the production activities of "RN-Yuganskneftegaz".
