Reposl has proved oil in a new part of its producing Teak B field in the offshore TSOP block, east of Trinidad. The TB4 well, drilled on the northern part of the field, flowed 1,200 b/d on test, and the area could hold over 40 MMbbl of in-place oil. Repsol and its Trinidadian partners Petroleum Co. of Trinidad and Tobago Ltd. (Petrotin) and The National Gas Co. of Trinidad and Tobago (NGC) planned to drill and complete two more wells this year on the block: these should lift production by 24% above last year's average of 10,900 b/d.

Brazil

Petrobras has started an extended well test in the western part of the Iara evaluation area, 300 km (186 mi) offshore in the presalt Santos basin. The FPSODynamicProducer is conducting the test on well 3-BRSA-1132-RJS, the first on Iara since its discovery in 2008. Its initial flow rate of 29,000 b/d was similar to that of other presalt wells currently producing from the basin. The partners must submit a declaration of commerciality to Agencia Nacional do Petroleo (ANP) around the turn of the year.

Currently presalt oil accounts for roughly 22% of Petrobras' overall production of 2.2 MMb/d. By 2018, the contribution should rise to 52% out of a total of 3.2 MMb/d – between now and late 2018 the company expects to have installed 19 new production platforms on its Santos basin presalt fields. Two, the FPSOsCidade de Mangaritiba and Cidade de Ilhabela, should start up later this year on Iracema South and Sapinhóa North.

Total S.A. has started production from its second deepwater cluster development in Angolan block 17. The location is 140 km (87 mi) offshore Luanda – water depths range from 1,100 to 1,400 m (3,609 to 4,593 ft). The Cravo, Lirio, Orquidea, and Violeta fields will eventually produce 160,000 b/d via 34 subsea wells and manifolds connected by 180 km (112 mi) of pipelines to the CLOV FPSO, with associated gas sent through another subsea pipeline to the onshore Angola LNG liquefaction plant.

As with Dalia, an earlier project in the block, CLOV produces lighter oil from the Oligocene and more viscous oil from Miocene, necessitating use of a subsea multi-phase pump system for boosting commingled fluids and enhancing oil recovery.

The converted FPSON'Goma, which previously served ExxonMobil's Xikomba development, arrived in June at Angola's Porto Amboim Estaleiros Navais Itda (Paenal) yard after sailing from Keppel Shipyard in Singapore. There it had undergone upgrades to the hull and turret. Among the new topsides modules, Paenal fabricated the sulfate removal package and the hot oil pump. The vessel, which now has 100,000 b/d oil processing capacity, will serve Eni's block 15/06 West Hub development.
