Qinghai Oil Province

Qinghai Oil Province is located in the Qaidam Basin in northwest China, with 23 oil & gas fields being identified.

On September 13, 1958, commercial oil flow blew out from well
Dizhong-4, marking the discovery of the Qinghai Lenghu Oilfield. In the mid-1990s, the discovery of the Tainan, SeBei-1, and Sebei-2 gas fields sharply raised natural gas resources of the province to 500 billion cubic meters, turning Qinghai into CNPC's fourth-largest natural gas producing province after Sichuan, Tarim and Changqing.

In 2008, 2.21 million tons of crude oil and 4.36 billion cubic meters of natural gas were produced in Qinghai Oil Province.

Sebei Gas Field

The development of Sebei-1 Gas Field began in 1995.

In 2002, 90.18 billion cubic meters was newly added to Sebei Gas Field's proven natural gas in place, bringing the cumulative total to 181.7 billion cubic meters.

In 2005, Sebei Gas Field had more than 130 gas producing wells, with a daily output of more than 6 million cubic meters. An annual production capacity of 2.4 billion cubic meters had been built. In 2006, the construction of Sebei-2 Gas Field well network was completed, with four gas gathering stations and one master station with a daily processing capacity of 1.85 million cubic meters.

Sebei Gas Field currently has an annual production capacity of 4 billion cubic meters, producing more than 10 million cubic meters natural gas every day.
