PEMEX has discovered four shallow-water fields in the Gulf of Mexico, reportedly with combined production potential of 200,000 b/d of oil and 170 MMcf/d (4.8 MMcm/d) of gas. All are close to shallow-water blocks newly opened to bidding under Mexico’s first international licensing round.

Dragados Offshore has won a contract to build and install a drilling platform for PEMEX’s Tekel field, 13 km (8 mi) west of the offshore Maloob field. Work is expected to be completed next summer.

Eni and Repsol have started gas production from the Perla field in the Cardón IV block in the Gulf of Venezuela, the country’s first offshore gas field development. Perla holds an estimated 17 tcf within a Mio-Oligocene carbonates reservoir, in a water depth of 60 m (197 ft). Development is in three phases, involving four relatively light platforms connected to 26 wells, with gas exported through a 30-in. subsea pipeline to a new two-train treatment complex onshore at Punto Fijo. PDVSA has contracted the gas for all three phases until 2036.

The FPSOCidade de Maricáberthed at the Brasa shipyard in Nitero-Rio, Brazil early last month following a 19,678-km (12,227-mi) voyage from the CXG yard in China. Some of the topsides modules were already fitted to the vessel – the remainder, built by Brasa and Rio-based EBSE, will be integrated in phases to the hull, with all work due to be completed by the end of this year. It will then be ready to start work for Petrobras on the Lula field in the presalt Santos basin. SBM Offshore, which will own and operate the FPSO under a joint venture, says its production capacity of 150,000 b/d of oil is the largest of its entire fleet.

Another newly-converted FPSO,Cidade de Itaguaí, was preparing to start production on the Iracema Norte area of the Lula field, following integration work at the BrasFELS shipyard in Angra dos Reis. The Schahin-Modec consortium-built and operated floater, moored in 2,240 m (7,349 ft) of water, can produce 150,000 b/d of oil and compress 8 MMcm/d (282 MMcf/d) of gas. This will be exported to the shore via a subsea pipeline.

Ophir Energy has awarded upstream front-end engineering and design (FEED) contracts for its Fortuna floating LNG (FLNG) project in block R offshore Equatorial Guinea. Under a competitive process, the McDermott Marine Construction/GE Oil & Gas UK and Subsea 7/Aker Solutions consortia are working on the subsea design scope, focusing in particular on cost and the number of wells required at start-up. Both are due to submit EPCIC tenders next March, with a final investment decision following in mid-2016.

Golar LNG will build and operate the 2.2 MMt/yr FLNG vesselGimi, which is due to start operating in mid-2019. Ophir is additionally considering a second FLNG vessel to process currently unallocated resources from block R, probably operating from the mid-2020s.
