Deepwater expenditure globally will total $120 billion over the next five years, according to Douglas-Westwood’s latestWorld Deepwater Market Forecast. Much of the focus in the initial period will be offshore West Africa and the Americas, with frontier regions becoming more prominent later on via projects such as Liza (Guyana), SNE (Senegal), and Zohr (Egypt). Various other mega-projects could go forward over the next 18 months, the analyst adds, as operators look to take advantage of lower service costs, with more than 118 deepwater fields set for drilling activity.
BP expects to produce first gas later this year from its $2-billion Juniper project, 50 mi (80 km) offshore Trinidad & Tobago in 360 ft (110 m) water depth. Heerema Marine Contractors’Thialf was preparing to install the platform, built by TOFCO in Trinidad and Gulf Marine Fabricators in Texas. It will produce 590 MMcf/d from the Corallita and Lantana fields, exported through a 10-km (6.2-mi) flowline to the Mahogany B hub.
Perenco has acquired Repsol’s 70% operated stake in the offshore Teak, Samaan and Poui block, southeast of Trinidad. The associated facilities have been producing 14,000 boe/d of late; Perenco is a specialist in extending the lives of mature fields.
Anadarko is drilling back-to-back exploration wells offshore western Colombia, in an attempt to prove further reserves close to its play-opening deepwater Kronos gas discovery.
