CNOOC South China Sea's western marginal oilfield development test project for reducing costs and increasing efficiency is put into operation

Recently, the second phase of the Weizhou 11-2 oilfield project of CNOOC Nanhai Western Oilfield was put into operation.
The first batch of 4 development wells tested daily output far exceeding the pre-drilling design allocation
.

The second phase of the Weizhou 11-2 Oilfield is located in the Beibu Gulf of the South China Sea, with an average water depth of about 40 meters.
The development is mainly based on the facilities of the Weizhou 11-2 Oilfield that were put into operation in 2012

Faced with construction difficulties such as large changes in formation pressure gradient and complex trajectories, the drilling team and the geological reservoir team worked closely to carry out research while drilling and optimize the trajectory in real time, effectively increasing the rate of reservoir drilling
.
On-site operators operate in accordance with the regulations to ensure operational safety and efficiency.
In the subsequent completion operations, a series of measures are taken to carefully care for the reservoir to maximize the release of reservoir productivity

The second phase of Weizhou 11-2 Oilfield is a cost-reducing and efficiency-increasing development test project for marginal oilfields in the western South China Sea.
Its commissioning is of positive significance to the realization of the planned goal of increasing production of 20 million cubic meters in the western South China Sea
