Tullow Oil to Bring Second Jubilee Well Online by Year-End as Noble Venturer Drillship Expands Offshore Ghana Drilling
Tullow Oil, the UK-headquartered independent energy company, is advancing its 2025/26 drilling campaign at the Jubilee oilfield offshore Ghana, with plans to bring its second producer well online by the end of 2025.
The development follows strong production results from the campaign’s first well and is being executed using the Noble Venturer drillship, owned by U.S.-based Noble Corporation.
According to Kosmos Energy, Tullow’s project partner, the first producer well came online in July 2025, achieving average production levels of around 10,000 barrels of oil equivalent per day during its first three months.
After scheduled maintenance, the Noble Venturer returned to the field in mid-October 2025 to spud the second producer well, which is expected to begin production before year-end.
Tullow contracted the Noble Venturer in December 2024 for a six-well campaign across its Ghanaian assets. The 2014-built, ultra-deepwater drillship is capable of operating in water depths up to 12,000 feet and drilling to a maximum depth of 40,000 feet.
Within the 2026 drilling campaign budget, the joint venture partners have approved expanded operations that now include four producer wells and one additional water injector.
In the third quarter of 2025, oil production at the Jubilee field averaged approximately 62,500 barrels per day (gross), reflecting consistent performance and strong reservoir output.
The Jubilee field, discovered in 2007 and brought onstream in late 2010, lies in deepwater depths of 1,100 to 1,700 meters, about 60 kilometers off Ghana’s western coast.
Tullow Oil operates the license with a 38.98% interest, while Kosmos Energy holds 28.61%, the Ghana National Petroleum Corporation (GNPC) owns 16.69%, and PetroSA holds 2.72%.
Meanwhile, at the TEN (Tweneboa, Enyenra, Ntomme) field, oil production averaged approximately 16,100 barrels per day (gross) in the third quarter.
The partners are finalizing a sale and purchase agreement (SPA) to acquire the TEN FPSO at the end of its current lease, with the deal expected to be signed by year-end to reduce operating costs.
Following the memorandum of understanding signed last quarter with the Government of Ghana, all documentation related to the extension of production licenses to 2040 has been completed and submitted for final government approval.
Tullow Oil’s continued investment in Ghana underscores its commitment to maximizing production efficiency, optimizing asset value, and supporting long-term energy growth in one of West Africa’s most productive offshore basins.
