French supermajor TotalEnergies has achieved first output from the second phase of the deep-water CLOV development on Block 17, off the coast of Angola.

The Phase 2 development involved the drilling of seven wells tied back to the existing CLOV floating production storage and offloading vessel and is expected to to reach a production plateau of 40,000 barrels of oil equivalent per day by mid-2022.

CLOV Phase 2 lies about 140 kilometres off the Angolan coast, in water depths ranging from 1100 to 1400 metres, and is estimated to hold resources totalling roughly 55 million boe.

CLOV is named after its four component reservoirs: Cravo, Lirio, Orquidea and Violeta (CLOV), and was estimated to hold proved reserves of 505 million barrels when it came onstream in 2014.

The CLOV FPSO is capable of handling 160,000 barrels of oil per day, with a water injection capacity of 319,000 bpd, while it has a storage capacity of 1.78 million barrels and a gas compression capacity of 6.5 million cubic metres per day.

CLOV Phase 2 marks the second major project start-up at Block 17 this year, with TotalEnergies firing up output from Zinia Phase 2 in May.

“The start of the production of CLOV Phase 2, a few months after Zinia Phase 2, demonstrates our continuous efforts to ensure a sustainable output on Block 17,” TotalEnergies senior vice president for Africa exploration and production, Henri-Max Ndong-Nzue, said Friday.

“This project fits within the company’s strategy to focus its upstream investments on low-cost projects which contribute to lower the average GHG (greenhouse gas) emissions intensity of its production.”

Block 17 is operated by TotalEnergies with a 38% stake, alongside Equinor (22.16%), ExxonMobil (19%), BP (15.84%) and Sonangol (5%).

The contractor group operates four FPSOs in the main production areas of the block, namely Girassol, Dalia, Pazflor and CLOV.
