CIGI urges increase in Arctic ops

The Center for International Governance Innovation (CIGI) issued a policy brief for the “New Arctic,” encouraging Canada’s federal government to devote greater policy attention and resources to Arctic maritime areas, including: better navigational aids, investment in ramps, breakwaters and windbreaks; infrastructure; Arctic deepwater ports; safety and security regulations; and a rigorous code of conduct for ships.

Rosneft studies Kara Sea

Rosneft, jointly with the RosHydroMet Arctic and Antarctic Research Institute, started a large-scale program of Kara Sea shelf studies as part of Kara Sea Summer 2013 Marine Expedition. During the expedition, meteorological stations will be installed at Novaya Zemlya archipelago, icebergs will be monitored, and buoys will be launched to monitor ice drift and settlement.

The data is required to assess potential environmental effects on future marine facilities, to be used for development of the Eastern Prinovozemelsky license areas.

TGS shots Canadian surveys

TGS announced two 2D surveys off Newfoundland and Labrador to define and delineate the Henley, Chidley, and Holton basins. The Labrador Sea Deep Basin 2D survey will cover 3000 line-km and the Labrador Sea 2D infill survey will cover 7100 line-km. The surveys will complement and infill the existing 22,167 line-km of 2D data acquired in 2011 and 2012. Data acquisition began in August and initial data will be available 2Q 2014.

Walter spuds relief well

Walter Oil & Gas Corp. began drilling on a relief well near its troubled A-3 natural gas well at South Timbalier 220, in the US Gulf of Mexico. The company, whose permit was recently approved by the US Bureau of Environmental Enforcement, is using the Rowan EXL-3 jackup. Once the relief well intercepts the target, drilling mud, followed by cement, will be pumped into the well.

A fire aboard the Hercules 265 jackup occurred in July, about 55mi (88km) off Louisiana. Operator Walter was completing a sidetracked well, when natural gas ignited. According to Hercules, the 44 people on board the rig were evacuated.

Santos basin discovery

Petrobras confirmed good quality oil (28°API) at Iara area, block BM-S-11, in the Santos basin presalt play, after drilling and testing well 3-RJS-706 (3-BRSA- 1132-RJS). The well is 226km off Rio de Janeiro state and 6km west of the discovery well in 2197m water depth. It was the fourth exploratory well on the block.

The carbonate reservoirs, which start at a depth of 5260m, have excellent porosity and permeability, better than the discovery well (1-RJS-656). Petrobras is the operator (65%) in partnership with BG E&P Brasil (25%) and Petrogal Brasil (10%).

Norvarg gas confirmed

Total’s appraisal drilling confirmed the “extensive” nature of the Norvarg gas discovery in the Barents Sea. Well 7225/3-2, in license PL 535 off Norway, was drilled in 377m water depth by using the Leiv Eiriksson semisubmersible. Norvarg was discovered in 2011, about 275 km north of the Hammerfest LNG plant on Melkøya Island, and was estimated to contain 10-50billion cu m of gas, equivalent to about 63-315MMboe.

Two production tests were done in the upper and lower parts of the Kobbe formation, with the well flowing at a maximum rate of 175,000cu m/d (about 6.2Mcf/d) on a 52/64in. choke. The well will be plugged and abandoned. Partners in the license are Total E&P Norge, operator (40%), North Energy (20%), Ithaca Petroleum Norge (13%), Statoil (10%), Det Norske (10%), and Rocksource Exploration Norway (7%).

TGS shoots West of Shetlands

Circle Oil buys Mahdia license

Irish independent Circle Oil announced that its subsidiary, Circle Oil Tunisia Ltd., has increased its stake in Mahdia license, offshore Tunisia to 100%, after acquiring the remaining 30% working interest from Tethys Oil & Mining Inc. for US$3 million. Circle Tunisia has identified multiple leads following a recent 3D seismic survey over the license area.

The company is highlighting two prospects: El Medouini and West El Medouini, containing an estimated 125MMbo and 75 MMbo unrisked, most-likely reserves, respectively. Circle will need to drill at Mahdia by July 19, 2014.

Yam Hadera estimate

Modiin Energy updated resource estimates for Yam Hadera field, off Israel. The best estimate of gross recoverable, prospective resources is 208MMbo (revised upwards from 133 MMbo) and 3.4Tcf of natural gas (revised upwards from 1.4 Tcf of natural gas). The estimates were prepared by Netherland Sewell & Associates Ltd., based on a 3D seismic survey of a 250sq km area around the prospect’s northern closure.

Tel Aviv-based Modiin Energy wholly owns the rights to the 400sq km Yam Hadera license. The license is about 30km off the Israeli coast, between Hadera and Haifa, in 500-1000m water depths and is directly northwest of Adira Energy’s Gabriella and Yitzhak license blocks.

ConocoPhillips acquires Senegal blocks

ConocoPhillips has agreed to acquire a 35% stake in three contiguous blocks off Senegal through two deals. The company is to acquire a 25% interest in all three blocks from Cairn Energy and a further 10% in the same blocks from FAR. The blocks are Rufisque, Sangomar, and Sangomar Deep, which cover about 7490sq km within the Mauritania-Senegal-Guinea Bissau basin.

Cairn has planned a twowell exploration program for 1H 2014, to target more than 1.5 billion bbls of undiscovered resource. Transocean’s semisubmersible Cajun Express will drill the wells.

FAR said the exploration campaign will test a shelf play and a deepwater fan play, and estimates total prospective resources at 3.58 billion bo.

Cairn will retain operatorship and 40% interest in the blocks during the exploration phase. Petrosen, the Senegal National Oil Co., will retain its 10% interest in the exploration phase, and FAR will hold 15%.

If commercial, Conoco- Phillips would have the option to become operator.

Eni discovery off Congo

Eni made an oil and gas discovery on the Nene Marine exploration prospect, in the Marine XII block, about 17km off Congo. Eni says two wells were drilled on Nene Marine and estimates it contains about 600 MMbo and 700Bcf of gas in place.

The first well, Nene Marine 1, was drilled in 24m water depth and encountered a wet gas and light oil accumulation in the Lower Cretaceous presalt clastic sequence. Nene Marine 2 was drilled 2km from the discovery well, confirming the hydrocarbons and reservoir continuity. Production tests on both wells flowed at a commercial rates with 37°API oil. Eni said it will continue the appraisal phase, while starting studies for commercial exploitation. Eni is operator of Marine XII block with 65% equity. Other partners are New Age, 25%, and Societé Nationale des Pétroles du Congo, with 10%.
