Qinhuangdao 27-3 Oilfield is located in the north-central waters of the Bohai Sea, with an average water depth of approximately 25 meters.
The main oil-bearing play is the Minghuazhen Formation of Neogene, and the oil property is medium-heavy crude.
The discovery well QHD27-3-3 was drilled and completed at a depth of 1,570 meters, which encountered a total of 48.9 meters oil pay zones.
The field has been tested to produce approximately 742 barrels of crude oil per day from a single well.
Through continued exploration, the proved in-place volume of Qinhuangdao 27-3 Oilfield has reached 104 million tons of oil equivalent.
Xu Changgui, Deputy Chief Exploration Officer of the company, said:
- Qinhuangdao 27-3 Oilfield is another major discovery with proved-in place volume over 100 million tons that we made in the north-central Bohai Sea in a decade;
- the successful discovery of the oilfield further demonstrates the oil and gas exploration potential in the complicated strike-slip fault zones of the Bohai Sea.
- over the years, we have been continuing to make new discoveries in the Bohai Sea, which further expand the resource base for offshore oil production growth;
- CNOOC Limited will focus on increasing reserves and production, to enhance our energy supply capacity, thereby contributing to the sustainable development of the economy and society.
