Côte d’Ivoire: Eni increases reserves at Baleine discovery by 25% with second successful well

Italian major Eni has announced the successful drilling and testing of the Baleine East-1X well within Block CI-802 offshore Côte d’Ivoire. This is the first well to be drilled in the block and targeting the Baleine structure discovered in 2021 in the adjacent Block CI-101.

Results from the wells have allowed to increase the volumes of hydrocarbons in place at Baleine from 2bn barrels of oil and 2.4 Tcf of associated gas to 2.5bn barrels of oil and 3.3 Tcf of associated gas, Eni has revealed.

The well is located 5km east of the Baleine-1X discovery well and reached  final depth of 3,165m (measured depth) in water depth of some 1,150m.

“From the vertical borehole a horizontal drain of 850 m in length was subsequently drilled into the reservoir to perform a production test that confirmed a potential of at least 12,000 bbl/d of oil and 14 Mscf/d of associated gas of production from the well Baleine East 1X,” Eni said.

In order to achieve First Oil from Baleine’s by H1 2023, Eni will be drilling a third well on the structure.

The company expects to produce 12,000 bopd and 17.5 MMscf/d from Phase 1 next year before ramping up to at least 75,000 bopd and 140 MMscf/d in a second phase due in 2026.  

Details on the ongoing development of the Baleine deepwater field are available in the “Projects” section within your Hawilti+ research terminal.
