BEIJING, March 26 (Reuters) - China extracted 861,400 cubic
metres of natural gas from methane hydrate, known as "flammable
ice", during an one-month trial production in the South China
Sea, state television reported on Thursday, citing the land and
resources ministry.
This production follows China's first experimental gas
extraction from methane hydrate in 2017, during which a total of
309,000 cubic metres of natural gas was produced in a 60-day
period.
Methane hydrate has been identified as a potential new gas
source for China and the South China Sea is believed to contain
some of the world's most promising deposits.
The Ministry of Land and Resources said the second
exploitation test has successfully brought gas extraction to the
stage of "trial production" from "experimental production",
which is considered a crucial step in the industrialisation of
methane hydrate.
The ministry also said the latest test adopted a horizontal
well drilling technique, the first time it has been used in
methane hydrate extraction.
