Venezuela and Trinidad and Tobago have sanctioned joint exploration for gas in the waters between the two countries, according to an AP report. However, Venezuela's government is said to have objected to ExxonMobil's planned drilling on the offshore Liza field, administered by Guyana but claimed by Venezuela. TheDeep Water Champion was due to start the program in March.
Petrobras' P-61 has entered service on the Papa-Terra field in the southern Campos basin offshore Brazil. This is the country's first tension leg wellhead platform, designed to accommodate dry completions. It is connected to a tender-assisted drilling platform and is equipped with a drilling and completion rig. Production is exported through subsea flexible flowlines to Papa-Terra's P-63 FPSO, which can process up to 140,000 b/d of oil.
In the Santos basin, a six-month early production system is in operation on a single well at Petrobras' Buzios field, 200 km (124 mi) from Rio de Janeiro in water depths of 1,600-2,100 m (5,249-6,890 ft). The FPSODynamic Producer's average output is restricted to 15,000 b/d of oil due to constraints on gas use. Results from the test will be used to optimize the field's first permanent production system, the P-74 platform, which is undergoing conversion at the Inhaúma shipyard in Rio.

Rosneft and Golar LNG are considering cooperation in liquefaction and transportation of natural gas. This could lead to Golar's floating LNG technologies being deployed on Rosneft gas field developments in Russia. Rosneft is currently building coastal support bases on its north coast and surveying soils in parts of the Barents and Okhotsk seas ahead of a planned drilling campaign in 2016.
In the Russian sector of the Caspian Sea, LUKOIL-Nizhnevolzhskneft is claiming a world record in horizontal drilling. A well drilled from an ice-resistant stationary platform on the Yuri Korchagin field extended for 4,908 m (16,102 ft) in the 9.5-in. section in one run, without the need for tripping. Total length of the well was 8,005 m (26,263 ft).
Morocco's government has awarded Mubadala Petroleum a reconnaissance license offshore the country's north coast. The company will perform a geological evaluation of the hydrocarbon potential of the 3,433-sq km (1,325-sq mi) Mediteranee Ouest area.
Eni has discovered potentially substantial volumes of gas and condensate in the Bahr Essalam South prospect, 82 km (51 mi) offshore Libya. The B1-16/4 well was drilled in 150 m (492 ft) of water, encountering hydrocarbons in the Eocene Metlaoui formation. The company is considering a fasttrack development with the other nearby Bahr Essalam structures.
In neighboring Egypt, the company has signed an agreement with the Petroleum and Mineral Resources Ministry to commit $5 billion to new projects over the next four years. These will develop 200 MMbbl of oil and 1.3 tcf of gas. The agreement includes an extension to some Eni permits in the Mediterranean offshore and the Gulf of Suez.
BP's deepwater Atoll-1 gas discovery in the North Damietta concession in the East Nile Delta could also be Egypt's deepest (subsurface) to date. The well, drilled by the semisubMaersk Discoverer in 923 m (3,028 ft) of water, initially encountered gas in Oligocene sandstones at a depth of 6,400 m (20,997 ft). It was then due to be deepened a further 1 km (0.6 mi) to test the same reservoir section that flowed gas from the 2013 Salamat discovery, 15 km (9.3 mi) to the south. Reserves in the concession are now thought to exceed 5 tcf.
Noble Energy and its partners in the deepwater Tamar project offshore Israel have signed a contract to export gas from the field over a seven-year period to Dolphinus Holdings.

Iran's President Hassan Rouhani has inaugurated Phase 12 of the South Pars gas/condensate field in the Persian Gulf. This is one of the widest-ranging phases in scope to date, producing 3 bcf/d of gas and 120,000 b/d from three main platforms and one satellite installation. It should raise Iran's annual gas output by more than 16%. Phases 15/16 and 17/18 are due to come onstream by July.
Statoil and ExxonMobil have scored their eighth deepwater gas find in block 2 offshore Tanzania. The Mdalasini-1 well was drilled in the southernmost part of the block in 2,296 m (7,533 ft) of water. Statoil estimates the in-place resource at 1-1.8 tcf, lifting the total gas volume proven in the concession to 22 tcf. The partners next plan to appraise the 2013 Tangawizi-1 discovery before taking a pause to determine their future options.
ONGC has increased oil production from its Western Offshore fields to 325,000 b/d of gas condensate, the highest figure for Mumbai Offshore in the past five years. The main factor in the rise was the tie-in of three marginal fields, 210 km (130 mi) west of Mumbai in 80-88 m (262-288 ft) of water, to the new FPSOSterling-II. This was installed last November and became operational in February.
