Production of oil and gas is the core activity of LUKOIL Group.
Liquid hydrocarbons represent approximately 80% of our overall production volumes. LUKOIL operates in six countries and accounts for approximately 2% of global oil production.
Excluding the West Qurna-2 project, our 2020 oil and gas condensate production totalled 77.2 million tonnes, down by 10.1 percent year-on-year. The volume and dynamics of the Company's oil production in Russia and at certain international projects were influenced by the parameters of OPEC+ agreement. LUKOIL swiftly responded to amendments in the agreement by flexibly adjusting its production.
In 2020, LUKOIL produced 73.5 million tonnes of crude oil and gas condensate in Russia, down by 10.5 percent yearon- year. This accounted for 14.3 percent of Russia's total production, as reported by the Central Dispatching Department of the Fuel and Energy Complex of Russia.
Amid the reduced total volume of oil production we continued to ramp up our production at priority projects as planned, while making production cuts at our mature fields in West Siberia, Timan-Pechora, and the Urals. In particular, we continued to increase production at our fields in North Caspian fields and low permeability fields (V. Vinogradov, Imilorskoye and Sredne-Nazymskoye fields in West Siberia), stepped up production of high-viscosity oil at the Yaregskoye and Usinskoye fields in Timan-Pechora, as well as at license blocks subject to the TAI (tax on additional income), including the Pyakyakhinskoye field. As a result, the share of these projects in LUKOIL Group's total production of oil and gas condensate, excluding the West Qurna-2 project, totalled 26 percent in 2020, up by four percentage points year-on-year.
In 2020, gas production came in at 29 billion cubic meters, down by 17.2 percent year-on-year.
Overall 2020 gas production in Russia totaled 17.6 billion cubic meters, down by 1.2 percent compared to 2019 as a result of reduced associated petroleum gas production following forced oil production cuts in line with the OPEC+ agreement. Natural gas production in Russia was up by 3.2 percent year-on-year after Phase 2 of the booster compressor station was commissioned at the Nakhodkinskoye field.
Gas production from our international projects declined by 33.8 percent to 11.4 billion cubic meters. The main negative impact came from lower production at projects in Uzbekistan amid a temporary decrease in China's demand due to the pandemic. Excluding Uzbekistan, we increased gas production from international projects by 11.6 percent driven by projects development in Azerbaijan and Kazakhstan and entrance into the Marine XII project in the Republic of Congo in 2019.
