Two of the offshore blocks awarded under Mexico's first licensing round this summer were in the shallow-water Sureste basin. Talos Energy operates blocks 2 and 7, both containing Tertiary clastic plays, according to partner Premier Oil. The partners will acquire and reprocess 3D seismic with a view to firming up drilling locations by the end of 2016.

Sonangol has agreed to acquire Cobalt International Energy's 40% operating interest in blocks 21/09 and 20/11 offshore Angola for $1.75 billion, subject to approvals. Until the transfer goes through, both parties will work to secure a final investment decision for the Cameia development in block 21/09 by year-end, with a view to deliver first oil in 2018.

Eastern Europe

Representatives from Gazprom, E.ON, Shell, OMV, and BASF/Wintershall have signed an agreement to construct two new gas lines for the Nord Stream II project in the Baltic Sea. These will supply 55 bcm/yr of Russian gas to markets in Europe via a reception point in Germany, doubling the current throughput of the existing Nord Stream pipelines. Gazprom will have a 51% share in the joint project company responsible for the program.

Mediterranean Sea

Rockhopper has received approval for the environmental impact assessment for its Ombrina Mare field development in the Adriatic Sea. Subsequent authorization from Italy's Ministry of Economic Development should complete the formal award of the surrounding production concession.

•••

Circle Oil has secured a renewal of the exploration permit for its Mahdia block offshore Tunisia until Jan. 19, 2018. The concession includes the 2014 El Mediouni (EMD-1) discovery well, which encountered oil in Ketatna (Oligo-Miocene) carbonates, although mud losses prevented logging. Circle, which has identified numerous other similar prospects, has committed to drill one exploration and one appraisal well and to acquire 3D seismic.

Eni claims to have proven a potential gas super-giant in the deepwater Shorouk block offshore Egypt. The Zohr 1X NFW well, drilled in 1,450 m (4,757 ft) of water, may have unlocked 30 tcf of lean gas covering an area of around 100 sq km (39 sq mi). The well encountered hydrocarbons in Miocene carbonates. Eni plans follow-up drilling, including a well targeting the structure's deeper Cretaceous potential.

Middle East

McDermott has scooped its largest single award ever in the region in the form of a lump-sum contract from Saudi Aramco for brownfield work on various fields offshore Saudi Arabia. The duration is until 2Q 2018. McDermott plans to assign much of the engineering and fabrication scope to its facilities in Al Khobar and Dammam, supported by its teams in Dubai and Chennai. McDermott vessels will handle all offshore installations.

ZADCO has extended Amec Foster Wheeler's project management consultancy contract for the UZ750 project, originally awarded in mid-2008. This involves a redevelopment of the offshore Upper Zakum oil field, 84 km (52 mi) northwest of Abu Dhabi, which is intended to sustain production at 1 MMb/d until at least 2050. Production is via four artificial islands with associated drilling and production facilities. All work under the extension must be completed by December 2017.

East Africa

ION Geophysical has a contract from the Puntland Petroleum Minerals Agency (PPMA) to acquire 8,000 km (4,971 mi) of 2D seismic over the entire Somalia Puntland offshore margin. Results from the program, designed to improve understanding of the sedimentary basin in this unexplored region, will assist a future license round initiative. PPMA has divided the Puntland offshore territory into 25 exploration blocks spanning a total area of 180,000 sq km (69,498 sq mi).

Aminex has secured a deferral of its obligation to drill two exploration wells in the Nyuni area offshore Tanzania from the Ministry of Energy and Mines. It also has approval to convert shallow-water 2D seismic commitments to acquisition of 3D data on the potentially more prospective deepwater portion of the license, and has started re-tendering for a contractor to perform the program.

Eastern Russia

Two Rosneft/Statoil joint ventures - Magadanmorneftegaz and Lisyanskmorneftegaz - have secured a rig for two exploration wells next year in the Sea of Okhotsk. The China Oilfield Services Ltd.-owned semisubmersible Nanhai-9 will drill in the Magadan-1 and Lisyansky areas, respectively 100 km (62 mi) and 90 km (56 mi) offshore, south of the Arctic Circle, in water depths below 150 m (492 ft).

Gazprom Geologarzvedka has approval to acquire 3D seismic in the Sea of Okhotsk offshore Sakhalin Island. The agreed program for this ecologically sensitive area, which followed detailed consultations, stipulates continuous environmental monitoring for all stages of operations. The company operates three license blocks offshore Sakhalin that include the Yuzhno-Kirinskoye field, recently added to the US government's list of sanctions in response to Russia's activity in Ukraine, according to Reuters. Export or transfers of oil will now require a license from the US Department of Commerce which is unlikely to be approved, Reuters reported.
