Russia's Gazprom is in the hunt for a contractor to shoot seismic over three large gas blocks in East Siberia as it aims to boost exports to its key China market.

The state-controlled gas monopoly has unveiled a plan to collect over 1400 square kilometres of 3D seismic data on the tracts that lie next to Gazprom’s largest asset in the area, the Kovykta gas field, which holds estimated recoverable reserves of 2.7 trillion cubic metres.

Gazprom gained the Mamyrinsky 1, 2 and 3 blocks, which together cover around 7000 square kilometres in the Irkutsk region, in 2019 as part of a long-term aim to unearth more gas reserves closer to China.
