Demand for subsea well intervention will remain high over the next five years, according to analysts Douglas-Westwood. Despite the oil price drop, they expect the number of subsea wells worldwide to rise by 41%, driven largely by an increase in ultra-deepwater developments. The fastest-growing market for intervention vessels and rigs will likely be Africa, while maturing subsea wells (more than five years old) will drive increased demand for workover units in North and South America and offshore Western Europe.
Husky Oil expects first oil in mid-year from the South White Rose satellite extension offshore Newfoundland & Labrador. A Hibernia-formation well underneath the North Amethyst field is expected to enter production this summer, the company adds.
Woodside Petroleum has completed a farm in to 20% of four licenses operated by BP offshore Nova Scotia. Water depths range from 500-3,600 m (1,640-11,811 ft). Exploration drilling is expected to start in 2017.

ExxonMobil has signed production-sharing agreements for two ultra-deepwater blocks in Côte d'Ivoire's portion of the Gulf of Guinea. Blocks CI-602 and CI-603 span a total area of 9,417 sq km (3,636 sq mi), in water depths of 3,000-4,000 m (9,843-13,123 ft).
Total has started harnessing associated gas from the shallow-water Ofon field in Nigeria's offshore Mining Lease 102. The gas is compressed and exported via a pipeline to shore for feedstock for Nigeria LNG. Ofon came onstream in 1997 and early this year was producing around 25,000 boe/d of oil and gas. The Phase 2 investments – new and modified platforms – will eventually lift output to 90,000 boe/d, with gas production of around 100 MMcf/d.
Lekoil and partner Green Energy have secured approvals for a well re-entry program at Nigeria's offshore Otakipo oil field. The company now expects production to start during the first half of this year, six months ahead of the previous target.
Eni has begun production from the 1.5-Bboe Nene Marine field in the Marine XII block, 17 km (10.6 mi) offshore Congo, 16 months after the initial discovery. The phased development will involve installation of production platforms and drilling of more than 30 wells with peak production of more than 140,000 boe/d (first-phase output is 7,500 boe/d). Water depth is 28 m (92 ft). Recently the company discovered more light oil and gas in the same block via a well on the Minsala Marine structure. In-place reserves could be 1 Bboe, of which 80% appears to be oil.
