With an average water depth of around 35m, the project is expected to reach peak production of 10,000 barrels of oil equivalent per day (boepd) by 2026.

The Weizhou 5-3 oilfield utilises one self-installing wellhead platform and uses nearby existing facilities for its development.

The production plan includes the commissioning of ten development wells, consisting of seven production wells, two water injection wells, and one gas injection well.
