Eni announces discovery at Ochigufu-1 well in Angola

Eni has announced a new oil discovery in Block 15/06, in the Ochigufu exploration prospect, in deep water offshore Angola. Oghigufu is the 10th commercial oil discovery made in Block 15/06. The new discovery is estimated to contain 300 million barrels of oil in place. Ochigufu 1 NFW well, which has led to the discovery, will be brought into production in record time. The well is located at approximately 150 kilometers off the coast and 9.8 kilometers from the Ngoma FPSO (West Hub) and the closeness to Ngoma FPSO allows the increase of the resource base of the West Hub project, currently underway. The well was drilled by the ‘Ocean Rig Poseidon’ Drilling Unit in a water depth of 1,337 meters and reached a total depth of 4,470 meters. Ochigufu 1 NFW was directionally drilled in order to reach the targets in optimal position and proved a net oil pay of 47 meters, (34° API) contained in the Lower Miocene and Oligocene sandstones with very good petrophysical properties. The data acquired in Ochigufu 1 well indicate a production capacity equal to more than 5,000 barrels of oil per day. Claudio Descalzi, Eni’s CEO said: "This important discovery, which will be brought into production in record time, adds even more value to Block 15/06. Like the recent discoveries in Congo and Gabon, this new find exemplifies the results we can achieve by applying leading edge technologies to exploration, and substantiates the decision to refocus Eni on key oil and gas competences". Studies are underway in order to evaluate an early tie-in to the Ngoma FPSO, already in location in the West Hub and designed to handle 100,000 barrels of oil production per day. Eni is operator of the Block 15/06 with a 35% stake. The other partners of the Joint Venture committed to the block are Sonangol P&P (30% stake), SSI Fifteen Limited (25% stake), Falcon Oil Holding Angola SA (5% stake) and Statoil Angola Block 15/06 (5% stake).

New high-impact discovery offshore Tanzania

Statoil and co-venturer ExxonMobil are pleased to announce their third high-impact discovery in Block 2 offshore Tanzania in a year. The discovery of 4-6 trillion cubic feet (Tcf) of natural gas in place in the Tangawizi-1 well brings the total in-place volumes up to 15-17 Tcf. "The success in Block 2 is the result of an ambitious and successful drilling campaign. We have so far completed five wells within 15 months and will continue with further wells later this year. Recoverable gas volumes in the range of 10-13 Tcf brings further robustness to a future decision on a potential LNG project," says Tim Dodson, executive vice president for Exploration in Statoil. The Tangawizi-1 discovery was made in sandstone of tertiary age. The new discovery is located 10 kilometres from the Zafarani and Lavani discoveries. It is located in water depth of 2,300 metres and was drilled by the Ocean Rig Poseidon drilling rig.

Statoil makes third discovery offshore Tanzania

Statoil today announces that the Lavani-2 exploration and appraisal well has resulted in a new natural gas discovery offshore Tanzania. The Statoil-operated Lavani-2 well successfully appraised the Lavani-1 discovery reservoir in the Palaeogene. When deepening the well to the second target, a separate and significant gas bearing reservoir in the Cretaceous was encountered. Statoil and its co-venturer ExxonMobil Exploration and Production Tanzania Limited will announce updated total volumes in Block 2 next year. An increase in the upside potential of the Block is expected following further evaluations of the well. The Lavani-2 discovery is the venture's third discovery in 2012. "These three discoveries continue to support our confidence in the Block 2 potential in Tanzania. The Lavani-2 well tested the deeper Saffron target and this new discovery looks promising," says Nick Maden, senior vice president in Exploration International in Statoil. The discovery is important for Statoil's international growth and demonstrates how Statoil's exploration strategy of focusing on high-impact opportunities is paying off. The Lavani-2 well also provides information that will be incorporated into models to help determine the optimal development concept for a possible natural gas development in Tanzania. "The Lavani-2 is the third well in an ambitious drilling campaign of four wells within one year. The next well will be the appraisal of the Zafarani discovery. In parallel the venture is acquiring new 3D seismic to help us identify additional targets in Block 2," adds Maden. "We are pleased to hear about additional gas resources in Block 2 and eagerly awaiting for further information," says the Minister for Energy and Minerals, Hon. Prof. Sospeter Muhongo. The Lavani-2 well was drilled to a total depth of 5270 metres in water depths of 2580 metres. The well was drilled by Ocean Rig Poseidon. The Lavani-2 well is located about 5 kilometres southeast of the Lavani-1 discovery well and 20 kilometres south of the Zafarani-1 well. Statoil operates the licence on Block 2 on behalf of Tanzania Petroleum Development Corporation (TPDC) and has a 65% working interest, with ExxonMobil Exploration and Production Tanzania Limited holding the remaining 35%. Statoil has been in Tanzania since 2007, when it was awarded the licence for Block 2.

Kabeljou-1 well returns poor results in Namibia

Chariot Oil & Gas Limited (Chariot), the Africa focused oil and gas exploration company, confirms that the Kabeljou-1 (2714/6-1) exploration well in Southern Block 2714A in the Orange basin offshore Namibia has reached a total depth of 3,150 metres TVDss and logging operations were conducted over the weekend. The well was drilled by the ‘Ocean Rig Poseidon’ drillship. Preliminary logging results indicate that no commercial hydrocarbons were found and the well will be plugged and abandoned. All pre-drill reservoir targets were evaluated. The well intersected the Nimrod delta as planned, although the reservoir was less developed than anticipated at this location. A comprehensive evaluation programme was conducted to further understand the stratigraphy, lithology and the nature of the formation fluids in this remote area. Detailed analyse will now by undertaken on the data collected and this information will be used to calibrate the existing data set. A resource update of the remaining prospectivity in the block will be provided once this evaluation has been completed.

Second high-impact discovery for Statoil offshore Tanzania

Statoil (OSE: STL, NYSE:STO) and partner ExxonMobil have made a large gas discovery in the Statoil-operated Block 2 licence in Tanzania. The logging results from the Lavani well confirm a new high-impact discovery for Statoil, with a preliminary resource estimate of 3 trillion cubic feet (Tcf) of gas in place. The Lavani well has encountered 95 metres of excellent quality reservoir sandstone with high porosity and high permeability. “The result from Lavani, which is only 16 kilometres south of our recent Zafarani discovery, confirms the high potential in Block 2. We are also pleased to announce that the recently drilled Zafarani sidetrack added another 1 Tcf of gas in place. This is in addition to the up to 5 Tcf announced in February. The results so far mark an important step towards a possible natural gas development in Tanzania,” says executive vice president for Exploration in Statoil, Tim Dodson. “The Lavani discovery demonstrates how Statoil’s strategy of focusing on high-impact opportunities is paying off and supports the company’s ambition for international growth,” Dodson adds. The Lavani well, drilled in 2,400-metre water depth, is the second exploration well in Block 2 – which covers an area of approximately 5,500 square kilometres. The well is drilled by Ocean Rig Poseidon with operations still ongoing. The Lavani discovery is the seventh high-impact discovery made by Statoil over the last 14 months. The other high-impact discoveries are Zafarani in Tanzania, Skrugard and Havis in the Barents Sea, Johan Sverdrup (formerly Aldous/Avaldsnes) in the North Sea, and Peregrino South and Pão de Açúcar (non-operated) in Brazil. Statoil operates the licence on Block 2 on behalf of Tanzania Petroleum Development Corporation (TPDC) and has a 65% working interest, with ExxonMobil Exploration and Production Tanzania Ltd. holding the remaining 35%. Statoil has been in Tanzania since 2007, when it was awarded the licence for Block 2. (*) ”High-impact well” = a total of more than 250 million barrels of oil equivalent (boe), or 100 million boe net to Statoil.

Statoil operated high impact gas discovery off Tanzania

Statoil (OSE:STL, NYSE:STO) and partner ExxonMobil have made a large gas discovery offshore Tanzania in the first exploration well in Block 2. Statoil announced on February 17 that the partnership had encountered indications of natural gas in the Zafarani exploration well in the Block 2 licence offshore Tanzania. The logging results now show that the discovery is a high impact discovery, so far proving up to 5 Tcf of gas in-place. The well has encountered 120 metres of excellent quality reservoir with high porosity and high permeability. The gas-water contact has not been established and drilling operations are on-going. “This discovery is the first Statoil operated discovery in East Africa and an important event for the future development of the Tanzanian gas industry. It is also a demonstration of how Statoil’s exploration strategy of early access and high impact opportunities strongly supports the company’s ambition for international growth,” says Tim Dodson, executive vice president for Exploration in Statoil. “This discovery could potentially be a catalyst for large scale natural gas developments in Tanzania,” says Yona Killaghane, Managing Director of Tanzania Petroleum Development Corporation (TPDC). Earlier this week the partnership signed an addendum to the production sharing agreement for Block 2 which stipulates the commercial terms in case of a development of natural gas resources in the block with the Tanzanian authorities. The Zafarani discovery is the fifth high impact discovery made by Statoil in the last 12 months, with the other discoveries being Skrugard and Havis in the Barents Sea, Johan Sverdrup (former Aldous/Avaldsnes) in the North Sea and Peregrino South in Brazil. Statoil operates the licence on Block 2 on behalf of TPDC and has a 65% working interest with ExxonMobil Exploration and Production Tanzania Ltd. holding the remaining 35%. Statoil has been in Tanzania since 2007 when it was awarded the licence for Block 2. TPDC has the right to a 10% working interest in case of a development phase. Zafarani is the first exploration well that has been drilled in the licence which covers an area of approximately 5,500 square kilometres. The water depth at the well location is 2,582 metres and the well itself will be drilled to reach an expected total depth of around 5,100 metres. The drillship, Ocean Rig Poseidon, will after completing the drilling activities at Zafarani move to drill a second well in Block 2 on the Lavani prospect.
