UK-headquartered Tullow Oil has decided to bring online its second well at the Jubilee oilfield off the coast of Ghana by year-end, following encouraging production results from the first well of its 2025/26 drilling campaign. The development is being executed using the Noble Venturer drillship owned by Noble Corporation, a U.S.-based offshore drilling giant.
According to Kosmos Energy, Tullow’s partner, the first producer well came online in July 2025, with initial production levels averaging around 10,000 barrels of oil equivalent per day through the first three months. Following scheduled maintenance, the Noble Venturer drillship returned to the field in mid-October 2025 and spudded the second planned producer well, which is expected to commence production around year-end.
Tullow hired the Noble Venturer drillship for a six-well campaign offshore Ghana in December 2024. The 2014-built vessel can operate in water depths of 12,000 feet and has a maximum drilling depth of 40,000 feet. Within the original 2026 drilling campaign budget, the joint venture partners have approved an expanded activity set that now includes four planned producers and an additional water injector. Oil production at Jubilee averaged approximately 62,500 barrels per day gross in the third quarter.
The Jubilee field is located in deepwater at depths ranging from 1,100 to 1,700 meters, approximately 60 kilometers offshore western Ghana. The field was discovered in 2007, with first production commencing in late 2010. Tullow operates the license and holds a 38.98 percent stake, with Kosmos holding 28.61 percent, Ghana National Petroleum Corporation 16.69 percent, and PetroSA 2.72 percent.
Regarding the TEN asset, where oil production averaged approximately 16,100 barrels per day gross for the third quarter, the partners are finalizing a sale and purchase agreement to acquire the TEN FPSO at the end of its current lease. The deal is planned to be signed by year-end to reduce operating costs. Following the signing of a memorandum of understanding with Ghana’s government last quarter, all documentation for the extension of production licenses to 2040 has been prepared for submission to the government for final approval.
