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.

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.
PA Resources and state oil company ETAP have completed work on their proposals for the southern tract of Zarat, one of Tunisia’s largest undeveloped offshore oil and gas fields. They plan a two-stage program involving standalone fixed facilities tied back to the BG-operated Miskar field platform, which has a pipeline link to the onshore Hannibal gas processing plant. Assuming agreement by Zarat’s northern tract partners, they aim to submit an overall unit development plan to Tunisia’s authorities.
Northern Petroleum was seeking a farm-in partner to co-fund a 3D seismic survey over two permits in the southern Adriatic Sea, after receiving approval from Italy’s authorities for the environmental impact assessment of the program. Northern aims to improve delineation of the 26-MMbbl Giove oil discovery and the 446-MMbbl Cygnus prospect.
