China's southwestern Sichuan Province has dug an industrial well that pumps gas from volcanic¹ stratum², the first of its kind in the Sichuan basin, a major gas production area in China.

 

四川省一眼工业井可以从火山岩地层中抽出天然气，这在四川盆地尚属首次。

 

Gas flared³ at the Yongtan 1 gas well in Zhoujia Township, the city of Jianyang, on Saturday, marking the success of the gas drilling, according to PetroChina Southwest Oil & Gasfield Company.

 

The well produced 225,000 cubic meters of natural gas per day during initial tests, the company said, adding that the area is estimated to have a huge gas reserve.

 

The successful gas drilling followed the discovery of thick volcanic strata⁴ that geologists⁵ believe contain abundant gas. Previously⁶, gas was mainly found in sedimentary rocks in the Sichuan basin.

 

Volcanic strata, formed by magma erupted from a volcano, have been a new frontier in the world's gas and oil exploration.
