China's state-owned oil and gas firm China National Offshore Oil Corporation (CNOOC) has started production at its Jinzhou 23-2 oil field development project in Bohai Sea.
The project is located in the northern part of the Bohai Sea, with an average water depth of approximately 13 meters.
The main production facilities include two new central processing platforms. A total of 67 development wells are planned to be commissioned, including 65 production wells and two water source wells.
The project is expected to achieve a peak production of approximately 17,000 barrels of oil equivalent per day in 2027. The oil property is heavy crude.
The Jinzhou 23-2 oilfield development project is the first multi-layer heavy oil thermal recovery project offshore China.
The project adopts the method of ’steam stimulation with chemical auxiliary steam flooding’ to reduce the viscosity of crude oil, thus effectively improve the utilization of reserves in offshore heavy oil field.
It will strengthen the energy supply to the Beijing-Tianjin-Hebei region, CNOOC said.
CNOOC holds 100% interest in the project and is the operator.
