FLNG set for second wave of investments

Worldwide expenditure on floating LNG could exceed $58.3 billion over the next seven years, according to a report from analyst Douglas-Westwood (DW). Compared with onshore LNG, FLNG facilities are more secure, can be developed more quickly, and are potentially a lower-cost alternative for stranded offshore gas fields, the analyst claims. Investments will likely dip in 2018 as the first installations are completed, recovering later in the decade as a second wave of projects gets under way. Yet-to-be sanctioned projects will target stranded gas offshore Australasia, the Eastern Mediterranean, East and West Africa, DW adds.

Petrobras has started production from the Iracema Norte area of the Lula field in the presalt Santos basin offshore Brazil. The first well online at the FPSOCidade de Itaguaíhas potential to flow 32,000 b/d. Eventually eight producers and nine injectors will be drilled, with peak oil production of 150,000 b/d in early 2017. The location is 240 km (149 mi) offshore in 2,220 m (7,283 ft) of water.

According to BG Group, the Petrobras-led BM-S-11 consortium has submitted initial development plans for the Atapú, Sururu and Berbigão fields, all within the wider Iara area in the Santos basin. The current proposal is for two lookalike FPSOs, with the first, serving Atapú, due to start operating in 2018. The other will be on Berbigão, tying in production from Sururu via subsea wells, although plans could change following operational experience.

West Africa

Xplorer has signed a memorandum of understanding to acquire a 36.75% interest from Teredo International in the shallow-water Boujdour permit offshore Morocco. The concession could hold oil and gas resources of up to 463 MMboe.

London-based Genel Energy, however, has opted to withdraw from the offshore Juby Maritime license following results from an appraisal well last year on an old heavy-oil discovery. Genel is also working with Morocco's government to determine the best way forward for its Sidi Moussa offshore license, where last year's SM-1 exploration well recovered oil to surface.

Total has started production from the Phase 1A development of the deepwater Dalia field in block 17, 135 km (84 mi) offshore Angola. This is designed to extract a further 51 MMbbl of reserves and sustain production through the FPSO, which came onstream in 2006, at around 200,000 b/d. The project involved debottlenecking of onboard treatment facilities and drilling seven infill wells.

On block 18, BP has brought online Phase III of the Greater Plutonio project. Here too the purpose is to sustain production levels through the FPSO, in this case via four new producers and two new water injector wells.

Mediterranean Sea

PA Resources and state oil company ETAP have submitted an updated plan for the 147-MMboe Zarat field offshore Tunisia, said to be the country's largest undeveloped offshore resource with similar geology to nearby producing fields such as Ashtart and Hasdrubal. The partners propose a phased development, with fixed facilities processing eventually up to 40,000 b/d of oil and 200 MMcf/d of gas from eight wells. If approved, the new complex could also serve as a hub for production from other stranded fields in the eastern Gulf of Gabes.
