Volga-Urals Region

Volga-Urals Region

In 2020, this region produced around 41 mmtoe of hydrocarbons (including 39 mmt of liquid hydrocarbons), or 16% of Rosneft’s total output. The Company’s key producing assets there include Bashneft-Dobycha, Orenburgneft, Samaraneftegaz and Udmurtneft.

Bashneft-Dobycha

Bashneft-Dobycha operates licence areas in the Republics of Bashkortostan and Tatarstan, the Orenburg Region, and the Khanty-Mansi Autonomous Area – Yugra. More than 50% of its proved reserves are concentrated in six major fields, including the Arlanskoye, Yugomashevskoye and Tuimazinskoye fields.

In 2020, Bashneft-Dobycha produced 11.5 mmtoe of hydrocarbons, including 11.2 mmt of liquid hydrocarbons.

The company performs high-impact well interventions and drills new wells to maintain robust oil production at its mature fields. In 2020, it performed 968 well interventions (in addition to drilling), with incremental production increasing by 4% vs 2019.

Bashneft-Dobycha stepped up production drilling, commissioning 153 new wells in 2020 (vs 114 a year before). The average flow rate of new wells increased by 7% year-on-year to 47.6 t per day as voidage replacement added 6 p.p.

The biggest drilling growth was seen at the Arlanskoye field, where 88 out of the region's 148 new wells were built. Given its complex geology, horizontal drilling with multi-stage hydraulic fracturing techniques has been used widely. Over 180 horizontal wells were commissioned at the field between 2016 and 2020. The use of advanced technology contributed to gains in productivity, with the average oil flow rate per well rising by 73% at Bashneft-Dobycha between 2009 and 2019. Oil production increased from 3.1 to 4.5 mmt at the Arlanskoye field over the same period.

Orenburgneft

More than 50% of Orenburgneft's proved reserves are concentrated in 10 major fields, including the Sorochinsko-Nikolskoye, Pokrovskoye, Olkhovskoye and Pronkinskoye fields.

In 2020, the company produced 14 mmtoe of hydrocarbons, including over 13 mmt of liquid hydrocarbons.

67 new production wells were drilled, resulting in an incremental production of 423 kt. The average daily flow rate per new well rose by 7% year-on-year to 47.6 t.

Also, a total of 42 sidetracks were drilled (up 7.7% vs 2019), with the incremental production at 84 kt.

The average daily flow rate of existing production wells reached 16.2 t per well (up 5% vs 2019) as voidage replacement added 3.5 p.p.and production recovery increased from 1.32 to 1.45 kt per well.

Samaraneftegaz

More than 50% of Samaraneftegaz's proved reserves are concentrated in eight major fields, including the Barinovsko-Lebyazhinskoye, Kuleshovskoye, Mukhanovskoye and Mikhailovsko-Kokhanskoye fields.

In 2020, the company produced 12.8 mmtoe of hydrocarbons, including 12.4 mmt of liquid hydrocarbons.

The number of hydraulic fracturing works increased by 11% to 103, a record high since 2012, with incremental production at 173 kt. Besides drilling, 377 well interventions were performed, up 6% vs 2019, resulting in 690 kt of incremental hydrocarbon production.

Production recovery stood at 1.42 kt per well, a 5.3% increase vs a year before.
