RN-Yuganskneftegaz, the largest oil producing asset of Rosneft, has produced the 570 millionth ton of oil at the Maysky region fields in the Khanty-Mansiysk Autonomous Okrug-Yugra.
The Maysky region is a group of 20 fields, including Malobalykskoye, Yuzhno-Balykskoye, Petelinskoye, Ugutskoye and others. A powerful production complex has been created in the region. The area of the oil field reaches 3.5 thousand square kilometers. Production is provided by about 3.4 thousand wells. In 2024, more than 360 new wells were commissioned in the region and more than 2.2 thousand hydraulic fracturing operations were carried out.
To increase the oil recovery factor, including at fields with complex geological structure, RN-Yuganskneftegaz specialists use advanced technologies and engineering solutions, such as infill drilling, construction of directional and horizontal wells with multi-stage hydraulic fracturing operations, and increasing the length of horizontal sections of wellbores. Drilling multi-hole wells using fishbone* technology has become new for the region. In 2024, four wells of this type were commissioned with an average starting oil flow rate of 327 tons/day.
Increasing the efficiency of production and introducing innovative technologies ensures high oil production rates at mature fields in the May region.
*”Fishbone” (English fishbone – “fish bone”) is a multi-hole well with a special trajectory, in which numerous branches depart from one horizontal shaft. The well’s shape resembles a fish skeleton – hence the name.
