Gas and oil reserves

Gazprom holds the world’s largest natural gas reserves. The Company’s share in the global and Russian reserves amounts to 17 and 72 per cent respectively. As of December 31, 2015, Gazprom Group’s A+B+C1 reserves reached 36.147 trillion cubic meters of gas and 3.6 billion tons of oil and condensate.

In order to replenish its resource base, Gazprom Group carries out geological exploration in Russia and abroad, as well as continuously monitors new projects and assets eligible for purchase.

Reserves of affiliates

In 2015, the A+B+C1 reserves of affiliates within the share of Gazprom Group stood at 1,035.5 billion cubic meters of gas and 679.0 million tons of liquid hydrocarbons.

Reserves audit

The PRMS-based audit of Gazprom Group’s hydrocarbon reserves carried out by DeGolyer & MacNaughton showed that, as of late 2015, the Group’s proven and probable hydrocarbon reserves included 23.7 trillion cubic meters of gas and 2.3 billion tons of oil and condensate.

The audit covered 94 per cent of gas, 92.2 per cent of condensate, and 92.4 per cent of oil reserves in the A+B+C1 categories.

Geological exploration

The main objectives of geological exploration performed by Gazprom Group are to replenish produced hydrocarbons by commercial reserves and prepare the feedstock base in promising regions. The growth rates of the Company’s natural gas and liquid hydrocarbon reserves have been surpassing the production rates since 2005 and 2008 respectively.

In 2015, the reserves replacement ratio was 1.27 for gas, 6.12 for condensate, and 0.47 for oil.

Gazprom operates in almost all of Russia’s oil- and gas-bearing regions. In 2015, Gazprom Group allocated a total of RUB 102.1 billion for the geological exploration of domestic hydrocarbons.

2015 saw the discovery of the Padinskoye field (Yamal-Nenets Autonomous Area), the coal-and methane-bearing Naryksko-Ostashkinskoye field (Kemerovo Region), and 28 new deposits.

Hydrocarbon development beyond Russia

Subject to the existing contract obligations, Gazprom Group continues to implement its ongoing projects in foreign countries. The amount of funds invested in geological exploration projects abroad totaled RUB 16.3 billion in 2015.

Gazprom Group is engaged in prospecting, exploration, and development activities in the CIS, Europe, Southeast Asia, Africa, Middle East, and Latin America.

The following projects are at the production stage: fields in blocks 05–2 and 05–3 located in the Vietnamese part of the South China Sea, the Wingate project on the North Sea shelf, the Shakhpakhty field in Uzbekistan, the Junin-6 project in Venezuela, which is implemented in cooperation with Rosneft, and the Garmian block in Iraq. Together with Wintershall, Gazprom produces oil and gas in Libya as part of the C96 and C97 oil concessions.

In the second half of 2014, Gazprom Group started producing hydrocarbons from the Badra field in Iraq. It is the first major upstream project outside Russia to be delivered by the Group from scratch. The unique experience gained in Iraq will be applied in the development of new fields both in Russia and internationally.

Mineral resource base development program

The resource base development strategy of Gazprom Group aims to maintain the balance between reserves growth and hydrocarbon production, as well as to ensure enhanced resource replenishment in the future.

In June 2011, the Gazprom Management Committee approved the Gas Industry Mineral Resource Base Development Program until 2035. The Program envisages the enhanced replenishment of the mineral resource base with due consideration of the changes in the reserve structure and the shift of the gas production centers to the new regions: the Yamal Peninsula, Eastern Siberia, the Far East, and the Russian continental shelf. The Program will provide for the addition of about 20 billion tons of fuel equivalent between 2011 and 2035.

The document places great emphasis on research and development activities, which will help dramatically improve the efficiency of prospecting and exploration activities at new hydrocarbon fields and deposits.
