Talos Energy and its partners may drill further targets on block 7 in the Sureste basin offshore Mexico after gaining a two-year extension to the license from CNH, the country’s National Hydrocarbons Commission. Prospects such as Pok-A-Tok and Xlapak could contain up to 150 MMboe in sands of similar age to those tested in the nearby giant Zama oil field, Talos claimed.

Cairn Energy expected to drill its first wells last month on block 9 in the same basin, with the jackup Maersk Developer focusing on the Alom and Bitol prospects. A discovery in either case could lead to swift follow-up appraisal drilling.

Tullow Oil has pulled off its second successive oil find in the Orinduik block off Guyana. The drillship Stena Forth drilled the Joe-1 well in 780 m (2,560 ft) of water in a previously untested Upper Tertiary play in the Guyana basin. The well, which followed the earlier Jethro discovery, encountered 14 m (46 ft) of net oil pay, and the result, Tullow said, has de-risked the western part of the block. Last month, Repsol was due to spud the shallow-water Carapa-1 well in Guyana’s Kanuku license, targeting a Cretaceous oil play.

The drillship Noble Tom Madden has delivered ExxonMobil’s 14th deepwater discovery in the country’s Stabroek block. The Tripletail-1 well in the Turbot development area penetrated 33 m (108 ft) of good-quality oil-bearing sandstone reservoir, 5 km (3 mi) northeast of the Longtail accumulation.

Petrobras’ newest FPSO the P-68 should be on location in the BM-S-11A concession in the presalt Santos basin offshore Brazil. The hull was constructed at the Rio Grande Shipyard, with topsides module integration following at the Jurong Aracruz Shipyard in Aracruz, Espirito Santo state. The vessel, to be moored in 2,280 m (7,480 ft) water depth, is due to start producing oil from the Berbigão and Sururu fields during the current quarter.

 Total has contracted Subsea 7 to lay 35 km (22 mi) of flexible pipelines and 20 km (12 mi) of umbilical for the Lapa North East field in the presalt Santos basin. The structures will connect five wells to the FPSO Cidade de Caraguatuba.

CGG is using the Geo Caribbean for Nebula 3D, an extensive long-offset BroadSeis survey over the Santos and Campos basins. The initial focus is on blocks offered under Brazil’s 15th license round, and the program will also take in areas where there is currently no 3D coverage.

Morocco’s government has awarded Irish independent Europa Oil & Gas the Inezgane Offshore exploration permit in the Agadir basin, an 11,228-sq km (4,335-sq mi) concession in water depths of 600-2,000 m (1,968-6,562 ft). Following ratification, Europa will operate in partner with state-owned ONHYM. Initial priorities will be to reprocess 1,300 sq km (502 sq mi) of 3D seismic and conduct technical studies, before deciding whether to commit to drilling under a second phase. The company has identified stacked prospects in the Lower Cretaceous fan sand play which it believes could each hold over 250 MMbbl.

Heerema Marine Contractors’ new semisubmersible crane vessel Sleipnir has successfully completed its first offshore job, installing the two main topsides on Noble Energy’s Leviathan platform offshore Israel. One of the operations, a 15,300-metric ton (16,865-ton) lift, established a new world record for a crane vessel, Heerema claimed. The combined weight of the modules was 24,500 metric tons (27,007 tons).

Golar will assess the viability of a new floating LNG solution to support future development of the 620-bcm Leviathan gas field. Initially, Noble and its partners plan gas exports to the Middle East area via existing pipelines, with an FLNG vessel potentially brought in later to export LNG to global markets. Golar’s study involves adapting its generic mark III newbuild concept to produce up to 5 MMt/yr.

The governments of Timor-Leste and Australia have signed a maritime border treaty which ends their border dispute in the Timor Sea. According to consultant Wood Mackenzie, the accord formalizes the governance structure and tax-sharing arrangement between the two countries, lifting some of the barriers that have held back the offshore Sunrise and Buffalo development projects. Woodside Energy, which operates Greater Sunrise, reportedly favors a program focused initially on the field’s large liquid resource, followed later by an LNG plant onshore Timor-Leste.
