CNOOC discovers China's first 100 billion square metre deep coal seam atmospheric field

On October 23, CNOOC announced the discovery of the Shenfu Deep Coal Seam Atmosphere Field, with proven geological reserves exceeding 100 billion square meters.

The Shenfu Deep Coal Seam Atmosphere Field is located in Yulin City, Shaanxi Province, on the eastern edge of the Ordos Basin. Through continuous research, CNOOC has innovated understanding of deep coal seam accumulation mechanisms, reservoir transformation, and differentiated extraction processes, strongly pushed deep coal seam exploration and development to a new level, and successfully discovered the Shenfu deep coal seam atmospheric field. The coal seam of the SM2-3 CH1 discovery well is 16.5 meters thick and the burial depth is about 2011 meters. It is a typical deep coalbed methane. After fracturing, the test daily output was about 19,000 cubic meters. After review and approval by relevant departments, the gas field has proven geological reserves of natural gas exceeding 110 billion cubic meters. It is China's first 100 billion square metre deep coal seam atmospheric field. It is also another major discovery made by CNOOC on land after the 100 billion square meter atmospheric field in Linxing, Shanxi.

The discovery of the Shenfu Deep Coalbed Atmosphere Field shows the broad prospects for exploration and development of deep coalbed methane reservoirs on the eastern edge of the Ordos Basin. It has important guiding significance for China's exploration of similar basin resources and the increase in storage and production of unconventional oil and gas, and lays a solid foundation for CNOOC to build a “trillion square metre atmospheric zone” onshore.

The third liquefaction production line of CNOOC's Donggu project was put into operation

On October 20, China National Offshore Petroleum Co., Ltd. announced that the newly built liquefied production line of Indonesia's Donggu LNG Project (Donggu Project for short) successfully transported the first ship of liquefied natural gas, marking the safe commissioning of the third liquefied natural gas production line of the Donggu Project.

The Donggu project is located in West Papua Province, Indonesia. It consists of 3 contract areas and includes a total of 6 offshore gas fields. The original two liquefaction production lines were put into operation in 2009, with a total production capacity of 7.6 million tons/year. After the third liquefied production line is put into operation, the total production capacity of the Donggu project will increase to 11.4 million tons/year, further consolidating its position as the largest gas field and the largest liquefied natural gas production center in Indonesia. Production facilities put into operation during the same period include: 2 newly built wellhead platforms, 10 production wells, and supporting infrastructure.
