ConocoPhillips Co. and Suncor Energy have agreed to join Shell's deepwater exploration program off Nova Scotia. They will acquire a collective 50% interest in six contiguous licenses that Shell operates in the Shelburne basin, 300 km (186 mi) from the Nova Scotia coast, in water depths varying from 500 to 3,500 m (1,640 to 11,480 ft).
McDermott's yard in Altamira, Mexico, has completed construction of a drilling platform that will serve Pemex's heavy-oil Ayatsil field development in the Campeche Sound in the Gulf of Mexico. The eight-leg jacket and deck, weighing a total of 11,535 metric tons (12,715 tons), was due to be installed in 115 m (377 ft) of water where it will be linked to three other platforms and an FPSO. Pemex has additionally contracted GE Oil & Gas to provide surface trees and wellheads for the drilling program, which will be manufactured in Ecatepec, Mexico City.
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.
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.
Woodside Energy Ltd. has agreed to farm into 25% of the undrilled Rabat Deep Offshore permits I-VI off northwest Morocco, with an option to double its interest and assume operatorship from current incumbent Chariot Oil & Gas Ltd. The concessions span 10,782 sq km (4,163 sq mi) in water depths out from 150 to 3,600 m (492 to 11,811 ft). Woodside already holds exploration acreage in the region off the Canary Islands.
Repsol S.A. may have started drilling off the Canaries after Spain's government reportedly rejected appeals against the program on environmental grounds. The company is said to be targeting over 400 MMbbl of oil in the Sandía and Zanahoria prospects off the islands of Fuerteventura and Lanzarote.
Lukoil and Cameroon Offshore Petroleum Ltd. (CAMOP) have conditionally agreed to farm into 50% of Bowleven plc's 75% stake in the Etinde permit offshore Cameroon, with CAMOP taking over as operator. Bowleven and its contractor Petrofac have been working on a phased hub-and-spoke development for the concession's gas which could serve a proposed fertilizer plant in Cameroon and Gaz de France's CLNG scheme. Phase 1 would focus on the IM field in the MLHP-7 block.
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.
Sasol Ltd. is admitting Eni as a 40% operating partner in exploration right permit 236, which covers acreage in the Durban and Zululand basin offshore Kwazulu-Natal province along South Africa's east coast.
