NNPC, ExxonMobil Meet As Usan Infill Work Begins On OML 138
NNPC Limited said it met ExxonMobil in Abuja to discuss boosting deepwater output and further offshore investments. The talks followed the start of work on ExxonMobil’s US$1 billion Usan Infill Project on OML 138, expected to add 40,000 bpd. ExxonMobil operates OML 138 under a production sharing contract with NNPC, which cited joint blocks and investment plans.
How this was made

The 30-second read
Why it matters
The key incremental information is that infill work has begun and ExxonMobil is engaging NNPC on additional deepwater investments, with a stated 40,000 bpd production uplift target upon completion.
Market read
For traders, this is a modest positive operational catalyst for ExxonMobil’s Nigeria deepwater narrative, but it lacks new financial or schedule specifics to drive a large repricing.
What to watch
Execution risk remains high in deepwater infill programs, and the article does not address regulatory, PSC economics changes, or whether the 40,000 bpd uplift is fully contingent on successful drilling and recovery assumptions.
Background
NNPC and ExxonMobil jointly hold OML 138 under a production sharing contract, and the Usan Infill Project is described as a US$1 billion effort to increase deepwater output.
Ticker impact
ExxonMobil is coordinating with NNPC on OML 138, with the Usan Infill Project expected to add 40,000 bpd and restart deepwater drilling activity.
Modest positive bias, with limited direct US-listed price impact unless follow-on milestones or funding details emerge.
The article is a project coordination update tied to a US$1 billion infill program and a stated 40,000 bpd increment, but it does not provide new financial guidance, contract terms, or timing beyond “infill work begins.”
Market effects
Supports a narrative of renewed deepwater investment activity in Nigeria, which can marginally improve sentiment for offshore operators and service demand.
Highlights continued operator-state collaboration in Nigeria’s offshore sector, potentially reducing perceived execution risk for future deepwater work.
Adds incremental supply narrative (40,000 bpd target) but is unlikely to move global benchmarks without confirmation of ramp timing and sustained output.
Counterpoint
The update may be largely operational and already anticipated; without confirmed capex drawdown, schedule, or production ramp timing, the market may discount it.
