Samaraneftegaz (part of Rosneft's oil and gas production complex) is celebrating 80 years since the start of development at the Mukhanovskoye field, the largest in the Samara region by reserves. Cumulative oil production at the field is approaching 200 million tons. At the current production rate, the reserves here will last for at least another 50 years.
Geological exploration near the village of Mukhanovo, located 90 kilometers from Samara, was conducted during the final years of World War II. With limited equipment and specialists available, several shallow wells were sunk to search for hydrocarbon deposits, which yielded a significant gas flow.
In November 1945, Kungur oil was extracted from exploration well No. 1 at a depth of 420 meters, with a daily flow rate of 35 tons. It turned out to be the lightest and highest-quality oil known in the Volga region at the time. In terms of gasoline yield, Kungur oil surpassed not only the deep-seated Devonian oil but also the oil from the Carboniferous Formation, the dominant formation at the time.
Intensive geological exploration at the Mukhanovskaya site led to another success: in 1952, a gushing flow of light oil was obtained from Lower Carboniferous deposits at a rate of 300 tons per day. Three years later, the oil potential of the Devonian deposits was proven, and industrial development began. The discovery of Devonian oil deposits became a crucial milestone in the development of the region's oil industry and played a significant role in the country's post-war economic recovery.
The secret to the Mukhanovskoye field's longevity lies in the accurate calculation of production rates and management, the professionalism of its employees, and the use of new technologies. Its 175 wells account for approximately 5% of the company's total production.
Geological studies of the productive strata are still ongoing. Since 2020, 10 new deposits have been discovered here.
Wells undergo regular geological and technical interventions aimed at increasing hydrocarbon production. Three horizontal wells drilled have significantly increased oil recovery due to greater reservoir coverage and the ability to develop low-yield and thin formations.
The field continues to test new technologies, such as polymer composition testing during repair and insulation work, modern methods of treating the bottomhole formation zone to clean the bottomhole, and others.
