Production from Chinguetti, Mauritania’s first offshore field development, will cease before year-end, due to a combination of natural decline and negative cash flow at current oil prices. Abandonment operations are due to start next year.
Woodside Energy is set to take a 65% operated interest in the PSC for the AGC Profond block offshore Senegal and Guinea-Bissau, in water depths of 1,400-3,700 m (4,593-12,139 ft). Current incumbent Impact Oil & Gas, which will retain a 20% interest, has identified prospectivity in Cretaceous and Jurassic margin plays on the east of the concession, similar to Cairn Energy’s deepwater oil finds off Senegal.
Tullow Oil is altering its operating procedures for the FPSO serving the Jubilee field offshore Ghana, after an inspection of the turret area identified a potential bearing issue. Precautionary measures include reducing the vessel’s degree of rotation.
New African Global Energy and Rift Petroleum have decided not to apply for an exploration right for their ultra-deepwater SW Orange basin technical co-operation permit offshore South Africa. Rift, owned by Tower Resources, will focus instead on its offshore Algoa-Gamtoos exploration right, which it views as more prospective in the near term.
The Russian Federation government has awarded Lukoil E&P rights for a block in the Russian sector of the Baltic Sea. This includes the D33 oil field, discovered last year by a well drilled by a Russian jackup, with estimate reserves of 21.2 million metric tons.
ExxonMobil and OMV Petrom have concluded their second round of exploratory drilling in the Neptun Deep block in the Romanian sector of the Black Sea. According to OMV, most of the seven wells encountered gas, although more analysis is needed to determine the permit’s full potential.
Bulgaria has reportedly authorized Shell to explore a deepwater Black Sea block for gas and oil. The five-year permit is for the 7,000-sq km (2,703-sq mi) Silistar concession, close to Neptun Deep on the Romanian side.
Edison and DEPA have signed a memorandum of understanding with Gazprom on a new gas pipeline across the Black Sea, taking supplies to Greece and Italy. This is said to be connected to the ITGI Poseidon project, which involves construction of a new network of onshore and offshore pipelines transporting gas from the Azeri sector of the Caspian Sea to southern Europe.
Noble Energy and its partners have submitted a revised development plan for the deepwater Leviathan gas/condensate field offshore Israel. The scheme, with an estimated cost of $5-6 billion (down from the previous estimate of $6-7 billion), calls for eight production wells linked via a subsea pipeline to a fixed platform containing all gas treatment systems, with initial throughput capacity of up to 12 bcm/yr. Under a second-phase development, this could be raised by a further 9 bcm/yr following the addition of four more wells. Depending on the outcome of a final investment decision late this year, first gas could flow in 4Q 2019.
Egypt’s government has issued Eni a development lease for the giant deepwater Zohr gas field, discovered in the Shorouk block last August. Eni plans to start production by end-2017, building output to a peak of around 75 MMcm/d by 2019. Main contractors for the project will be Petrojet, Enppi and Saipem, which have all worked on Eni’s previous Egyptian projects. Recently Eni completed a successful appraisal well on Zohr, 1.5 km (0.9 mi) southeast of the discovery well in 4,800 ft (1,463 m) of water.
