In 2018, the Company’s total production of hydrocarbons amounted to 48.4 mmtoe (including 46.4 mmt of liquid hydrocarbons, or 20% of Rosneft’s total production). The key producing assets in the region are Bashneft-Dobycha, Orenburgneft, Samaraneftegaz and Udmurtneft.
A unique proppant fracture acidizing is used by Russian regional subsidiaries, which mainly operate carbonate reservoirs. This concept ensures acid delivery along the considerable distance from the wellbore, creation and stabilization of the propped fracture.
Samaraneftegaz operates 171 license areas (including 170 license areas as a subsoil user) located in the Samara and Orenburg Regions. About half of all proved reserves are concentrated in 10 major fields, including the Mukhanovskoye, Kuleshovskoye, Barinovsko-Lebyazhinskoye, Mikhailovsko-Kokhanskoye, and Neklyudovskoye fields.
In 2018, hydrocarbons output totaled 12.5 mmtoe, with liquid hydrocarbons production of 12.1 mmt taking into account the Company’s obligations under the OPEC+ agreement.
Samaraneftegaz focuses on commissioning of new wells, using advanced technologies, and conducting effective well interventions to maintain a high level of crude oil production potential.
Since the launch of the company’s operations in 1936, its cumulative oil production has exceeded 1.2 bln tonnes.
Orenburgneft operates 130 license areas (including 128 license areas as a subsoil user) in the Orenburg, Saratov, and Samara Regions. More than half of all proved reserves are concentrated in 10 major fields, including the Rostashinskoye, Sorochinsko-Nikolskoye, Garshinskoye, Pokrovskoye, and other fields.
In 2018, hydrocarbons output totaled 16.0 mmtoe, with liquid hydrocarbons production of 14.9 mmt taking into account the Company’s obligations under the OPEC+ agreement.
In maintaining hydrocarbon production, the main objectives are the application of state-of-the-art well intervention techniques and the optimization of both well operations and reservoir pressure maintenance systems. The average annual flow rate of new wells increased by 30% year-on-year.
Orenburgneft is commissioning successful exploration wells and dependent production wells by using system analysis of resource the base at open structures. Six production wells were commissioned in 2018 at the Bakhtiyarovskoye field with the average annual flow rate of more than 100 tonnes per day.
Bashneft-Dobycha operates 254 license areas (with Bashneft as a subsoil user) located in the Republics of Bashkortostan and Tatarstan, the Orenburg Region, and the Khanty-Mansi Autonomous Area – Yugra. More than half of all proved reserves are concentrated within six major fields, including the Arlanskoye, Yugomashevskoye, and Tuimazinskoye fields.
Hydrocarbons output totaled 16,8 mmtoe in 2018, with liquid hydrocarbons production of 16.4 mmt.
The company supports effective well interventions and drilling of new wells to maintain a high crude oil production level at mature fields.
