CNPC has found natural gas in southwest China's Sichuan basin

The Chinese National Petroleum Corporation has announced that its subsidiary, PetroChina, has found natural gas in southwest China's Sichuan basin. The Ministry of Land and Resources has certified the newly found gas in the Longwangmiao formation of Cambrian system, which is located in the Moxi block of Anyue gas field.

It is about 440.385 billion cubic meters with technically recoverable reserves estimated at around 308.2 billion cubic meters.

CNPC reveals that the gas find is “the largest monomer marine uncompartmentalized carbonate gas reservoir discovered in China up to now, featured by large reserve scale, broad gas-bearing areas, high formation pressure, high gas flow, and superior gas components.”  

The production test has made an average per well daily output of 1.1 million cubic meters, and the wells in production have produced about 0.6 million cubic meters per day on average.

Since 2011, CNPC has drilled two exploration wells, the Gaoshi-1 and Moxi-8, which have both attained high-yield gas flows of one million cubic meters per day from the Simian system as well as the Cambrian system.

CNPC disclosed that it took them “less than two years to find the Longwangmiao gas reservoir,” identify its reserves and conduct a production test with a 1 billion cubic meter capacity.

The “phase-I capacity building project” of 4 billion cubic meters is presently underway, and the “phase-II capacity building project” of 6 billion cubic meters has also started.

Currently, the gas production test at the Moxi block has yielded more than 600 million cubic meters in total.
