Overview

This analysis maps gas hydrate reservoirs and predicts resources in Russia's economic zones, indicating vast methane potential.

Key Points

  • Gas hydrate reservoirs in Russian seas and Lake Baikal are estimated to hold 520 trillion km3 of gas.
  • The assessment identified 203 gas hydrate accumulations based on extensive digital seismic and sediment data.
  • Reserves in gas hydrate accumulations vary significantly, with some as small as 0.1 billion m3 and others exceeding 300 billion m3.
  • Methane constitutes just over 10% of the estimated global gas hydrate resource value exceeding 147 trillion m3.
