(ECNS) -- The Sulige Gas Field, China's largest unconventional onshore gas production field located in the Ordos Basin of north China's Inner Mongolia Autonomous Region, has reached an annual output of 30 billion million cubic meters, which is the first time in China, PetroChina said on Monday.
The Sulige Gas Field 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 reached daily output of 100 million cubic meters this year, and its gas output had exceeded 300 billion cubic meters in total.
