Yamal Peninsula Exploration of the Yamal peninsula has found reserves of over 10 trillion cubic metres of natural gas and over 500 million tons of oil and gas condensate. About 60 percent of these reserves are located in Bovanenkovo, Kharasavey and Novoportovo. The natural gas production capacity of the Bovanenkovo field was estimated to be , with potential to increase to . Shtokman field The Shtokman field is one of the world's largest natural gas fields. It is located in the central part of the Barents Sea, northeast of the city of Murmansk and west of the Yamal Peninsula. The field is estimated to contain up to of gas. Potential production is in the initial phases, with a potential increase to . Gazprom, TotalEnergies (France) and Statoil (Norway) created a joint company Shtokman Development AG for development of the field.

Exploration In 2008, Gazprom carried out of explorative well drilling; of 2D seismic and of 3D seismic survey. As a result, gas reserves grew by , and crude oil and gas condensate reserves grew by 61 million tons. Gazprom carries out prospecting and exploration in foreign countries such as India, Pakistan, Algeria, Venezuela, Vietnam, Libya, Kazakhstan, Uzbekistan, Kyrgyzstan and Tajikistan. Transportation Gazprom's Unified Gas Supply System (UGSS) includes of gas trunklines and branches and 218 compressor stations with a 41.4 GW capacity. The UGSS is the largest gas transmission system in the world. In 2008, the transportation system carried of gas. Gazprom has claimed the UGSS has reached its capacity. Major transmission projects include the Nord Stream pipelines as well as pipelines inside Russia. Russia has two liquefied natural gas (LNG) production plants, Yamal LNG and Sakhalin-2 LNG. In March 2021, the Russian Government authorised a long-term programme to develop nine more LNG plants, to address the growing global LNG market. In October 2021, Gazprom and RusGazDobycha announced they would build the first new
