Nigeria’s Niger Delta Basin is dotted with mature hydrocarbon fields, many of which lie idle or stranded — from onshore terrain to shallow offshore waters. Large international oil companies (IOCs) often deem these fields economically unviable once their initial production phase has passed. Remaining reserves are either too small or located too far from existing infrastructure to justify the high cost of maintenance and production.
Security challenges and community tensions add further complications, leaving many fields abandoned.
For IOCs, two main options often exist:
- Divestment: Handing over operatorship to capable indigenous players (often called marginal operators) who can reactivate the assets.
- Redevelopment: Rolling out measures to extract additional hydrocarbons from existing fields, sometimes decades after their initial production.
Such operations are rarely straightforward. They often require heavy capital expenditure to revive neglected wellheads and corroded pipelines. In some cases, new wells must be drilled within the original well pattern to tap pockets of oil or gas left untouched in heterogeneous reservoirs.
“Project Panther”
Chevron is pursuing this second option through Project Panther, a major infill drilling and redevelopment initiative in partnership with state-owned NNPC. The project aims to boost output from ageing fields while making use of existing infrastructure and reducing carbon intensity.
Launched in late 2022 with $1.4bn in external financing facilitated by Standard Chartered Bank UK and United Bank for Africa (UBA), with a consortium of 16 international and local lenders.
Project Panther will drill 37 development wells — 31 oil producers, one gas well, and five water injectors — across 10 fields in the Niger Delta, specifically within OMLs 49, 90, and 95 in the offshore and onshore Escravos areas.
By completion in late 2027, the initiative is expected to deliver approximately 166 million barrels of oil and 97 million barrels of oil‑equivalent gas.
A key objective is to route all produced gas to meet domestic supply obligations, supporting Nigeria’s energy transition by providing cleaner fuel for local power generation and industry. The government anticipates earning more than $6bn in royalties and taxes over 20 years from the project.
Execution and progress
Project Panther is currently in its peak execution phase. Recent reports highlight significant logistics activity, including the delivery of flexible pipelines to offshore sites.
As of late 2024 and throughout 2025, Chevron has deployed at least one jack‑up rig in shallow offshore areas and one swamp rig for the campaign. Project Panther One was about 80% complete by mid‑2025, despite some delays, with this phase focusing on gas supply from 27 wells.
Major installation phases — including jackets and flowlines — have been completed, such as a 32‑kilometre onshore flowline that reached 80% completion in early 2025.
Beyond the 37 wells, the joint venture has leveraged rig availability for nearby exploration. This led to the Awodi‑07 discovery in late 2025, confirming 675 feet of hydrocarbon presence across several reservoirs in the shallow offshore western Niger Delta. Other discoveries include the Meji NW‑1 well in late 2024, with 690 feet of gross hydrocarbon pay, and a third well whose details remain undisclosed.
In essence, Project Panther is a “life extension” programme for mature fields, particularly targeting the Agbami and Escravos areas. By offsetting natural production declines, Chevron and NNPC aim to sustain Nigeria’s oil output while advancing its energy transition goals.
