Chinese Pick Up Drilling Where Shell Made a Discovery in Deepwater Gabon

China National Offshore Operating Company CNOOC will spud the first of a two well campaign in two blocks divested by Shell in deepwater Gabon.

The campaign is for one well each to be drilled in first quarter 2023 in blocks BC-9 and BCD-10. The latter was where Shell encountered 200 metres of net gas pay while drilling the Leopard-1 wildcat in 2014. Shell was excited by the result at the time and there were speculations (that Shell did not refute), of potential resource of 10Trillion cubic feet of gas in the Leopard structure, which is located below a salt (carbonate) formation.

Shell has since divested from Gabon entirely, with CNOOC Ltd, its partner in the 2014 discovery, taking over 100% and operatorship of both assets in an acquisition finalized in 2019.

For the campaign, CNOOChas inked a contract with rig operator Stena Drilling, for mobile offshore drilling unit (MODU) Stena Icemax. The two (2) well programme has an estimated total campaign duration of 90 days.

The dynamically-positioned dual mast Stena IceMax is a harsh-environment ice-class drillship with managed pressure drilling capabilities.

The drilling programme is crucial to the Gabonese authorities, who have struggled, in vain for the last 30 years, to place Gabon on the deepwater production map of the world. It is the only African oil producing country, lying on the edge of the south Atlantic, without crude oil or gas output from thedeepwater terrain.
