Short-term FPSO outlook strong

Investments in floating production systems worldwide are set to soar to $21 billion in 2017, up from $12 billion this year, according to Douglas-Westwood's latest market forecast. However, both figures apply mainly to commissioned facilities - the outlook for new orders looks poor, the analysts claimed, with the oil price decline likely to delay sanction of various new projects.

FPSOs comprise the largest segment of the market between 2015-2019, accounting for 87 installations and 81% of the forecast capex, followed by TLPs and other floating production systems. Almost one-third of the forecast installations are for Latin America, with 68% of the facilities globally destined for deepwater projects.

The Bahamas

A second reading of a new Petroleum Act was due to go before the Bahamian parliament this winter, and following a consultation phase the proposals should pass via the senate into law. Bahamas Petroleum Co., which has completed studies for a drilling campaign offshore the Bahamas, says it remains committed to spudding its first well as soon as possible.

South America

Tullow Oil plans to acquire 4,000 sq km (1,544 sq mi) of 3D seismic over block 54 offshore Suriname. This summer, the company expects to participate in a well operated by Teikoku Oil on the Spari prospect in offshore block 31.

The semisubmersible Eirik Raude was due to sail into Stanley harbor at the end of February to prepare for a six-well exploration campaign on various licenses offshore the Falkland Islands. Rockhopper will participate in four wells, all in the North Falkland basin (NFB), with the first likely to be on the Zebedee prospect.

Rockhopper's partner Premier Oil is assessing design options for a leased FPSO for its planned first-phase development of the Sea Lion oil field in the NFB. This would be connected to a single subsea drill center. The company is currently targeting sanction for this phase during 1Q 2016, and hopes to bring in a partner to co-fund this and subsequent phases that could involve more FPSOs or a TLP.

West Africa

Kosmos Energy has agreed to farm out to Chevron 30% of its interest in three contiguous concessions offshore Mauritania. Water depths over blocks C8, C12, and C13 range from 5,249-9,842 ft (1,600-3,000 m). Assuming approval from the government for the transaction, Kosmos would remain operator in the exploration phase with Chevron assuming control in the event of a commercial discovery.

Tullow has agreed to transfer a 40.5% stake in Mauritania's shallow-water block C-3 to Sterling Energy for around $2.5 million, in consideration for past costs. Tullow is due to process 1,600 km (994 mi) of newly acquired 2D seismic over the block, fulfilling its Phase 1 commitments. If the partners opt to enter the next two phases, the obligations include 3D seismic and two wells. Sterling sees this as an emerging shelf play, following Cairn Energy's 2014 SNE-1 oil discovery off Senegal to the south.

•••

Offshore Cameroon, Sterling is hoping for government approval to assume Murphy's 50% operated interest in the Ntem concession, where water depths vary from 400-2,000 m (1,312-6,562 ft). Last year the partners drilled the unsuccessful Bamboo-1 well on the concession, which is in the prospective southern Douala/Rio Muni basin.

Eni has a new gas/condensate discovery offshore Gabon. The Nyone Deep 1 well was drilled in block D4. Eni assessed in-placed resources at around 500 MMboe.

Mediterranean Sea

PA Resources (PAR) has canceled a proposed sale of operating interests to EnQuest in the Didon oil field and the Zarat permit offshore Tunisia. This follows the failure of the Tunisian authorities to issue a letter of non-objection to the transaction. PAR says it is continuing studies on Zarat, the country's largest unexploited gas discovery, and aims to submit a development plan later this year.

North Caspian Operating Co. has contracted Saipem for further pipelay for the shallow-water Kashagan field in the Kazakh sector of the Caspian Sea. Under the $1.8-billion program, Saipem will install two 95-km (59-mi), 28-in. carbon steel pipelines, internally clad with a corrosion alloy layer, connecting the offshore D island with the onshore plant at Karabatan. The offshore sections of the lines will be around 65 km (40 mi) long. Work is expected to be completed by the end of 2016.

Production at Kashagan had to be suspended soon after start-up in late 2013 following stress cracking in the pipeline system caused by hydrogen sulfide (H2S) in the field's wellstream.

Middle East

The heavy-lift barge Lan Jing has installed the Hasbah tie-in platform (TP) for Saudi Aramco offshore Saudi Arabia. The vessel's 7,500-ton crane lifted a weight of around 5,000 tons, a new record for an Aramco heavy-lift operation.

Additionally, the vessel installed the 4,600-ton Arabiyah field tie-in platform and a 1,800-ton intermediate injection platform. The Arabiyah-Hasbah gas fields project is designed to supply 2.5 bcf/d to the onshore gas plant at Wasit.

Iran Offshore Oil Co.'s new 2.2-MMbbl floating storage unit/export terminal has started operating in the Persian Gulf. It is designed to receive and store 200,000 b/d of produced crude from the offshore Norouz and Soroush fields. News service Shana claimed the double-hulled FSU is the largest of its type in the world, at 337 m (1,105 ft) long, 60 m (197 ft) wide, and 33 m (108 ft) high.

East Africa

Anadarko proved gas from two reservoirs with its latest appraisal well on the deepwater Orca discovery in Mozambique's Offshore Area 1. It has since drilled a further well on the 2014 Tubarão Tigre gas discovery. The Area 1 partners continue to negotiate long-term gas sales from their various fields which they plan to develop via LNG. They currently have heads of agreement in place to supply more than 8 MM metric tons/yr (8.8 MM tons/yr), Anadarko said.
