China National Petroleum Corp. has confirmed that its Moxi block in the Anyue gas field contains technically recoverable reserves of up to 308.2 billion cu m.

The Longwangmiao formation, in the Cambrian system, is the largest monomer marine uncompartmentalized carbonate gas reservoir discovered in China to date, according to a statement from China’s Ministry of Land and Resources.

CNPC also said production tests have obtained 1.1 million cu m/day. Both wells, Gaoshi-1 and Moxi-8, are yielding an average 600,000 cu m/day. The wells are producing from the Simian and Cambrian systems, respectively.

Located in the paleo uplift of China’s central Sichuan basin, the Anyue gas field features high formation pressure, high gas flow, and superior gas components, CNPC said.

CNPC and its subsidiary, PetroChina Co., have been actively exploring the Longwangmiao reservoir since 2012. The company reported that its current tests have a cumulative capacity of 1 billion cu m. With completion of its Phase-I development, the company expects to increase this number to 4 billion cu m. Phase-II, which has also begun, will bring this capacity to 6 billion cu m, the company said.

Cumulative production at Anyue’s Moxi block is 600 million cu m to date.
