China's largest unconventional onshore gas production field, located in north China's Inner Mongolia Autonomous Region, has reached daily output of 100 million cubic meters, PetroChina said on Saturday.
Operated by PetroChina, China's largest oil and natural gas producer, the Sulige Gas Field located north of the Ordos Basin in Inner Mongolia is the main source of gas supply to the Beijing-Tianjin area and cities around Inner Mongolia.
The new daily gas production output record can supply the daily gas demand of 50 million households.
The Sulige Gas Field is characterized by its low porosity and low permeability tight sandstones, creating perfect condition for containing tight gas, a principal natural gas resource for gas reserves and production growth in China.
It has a proven gas reserve of 4.77 trillion cubic meters and its annual gas output had exceeded 300 billion cubic meters as of 2021.
