Two minor gas/condensate/oil discoveries in the Norwegian Sea - 6407/7-9 S and 6407/7-9 A

Statoil Petroleum AS, operator of production licence 107 C, has completed the drilling of wildcat wells 6407/7-9 S and 6407/7-9 A. The wells were drilled about six kilometres north of the Njord field in the southern part of the Norwegian Sea and about 137 kilometres north of Kristiansund. The primary exploration target for the wells was to prove petroleum in Early and Middle Jurassic reservoir rocks (Ile and Tilje formation) and the secondary exploration target was to prove Early Jurassic reservoir rocks (Åre formation). Well 6407/7-9 S encountered a 102-metre oil column in the Ile formation, and a 157-metre gas/condensate column in the Tilje formation. The reservoir properties in both reservoirs are poor to moderate. The well did not encounter a reservoir in the Åre formation. A few thin sand layers were encountered in the Lange formation in the Cretaceous, some with petroleum, but with poor reservoir properties. Preliminary estimates place the size of the discovery between 0.2 and 3 million standard cubic metres (Sm3) of recoverable oil equivalents. Well 6407/7-9 A encountered a 195-metre gas column in the Tilje formation and a 140-metre gas column in the Åre formation. Mobile petroleum was not proven in the Ile formation. The reservoir properties in the reservoirs are poor to moderate. Preliminary estimates place the size of the discovery between 0.1 and 1.5 million standard cubic metres (Sm3) of recoverable oil equivalents. The licensees will consider the discoveries along with other nearby discoveries with regard to a development with tie-in to the Njord field. The wells were not formation-tested, but extensive data acquisition and sampling were carried out. The wells are the first two exploration wells in production licence 107 C. The licence was awarded in APA 2008. Wells 6407/7-9 S and 6407/7-9 A were drilled to measured depths of 4114 metres and 4931 metres below the sea surface, respectively, and vertical depths of 4105 metres and 4127 metres below the sea surface, respectively. Both wells were terminated in the Åre formation from the Early Jurassic Age. Water depth is 323 metres. The wells will now be permanently plugged and abandoned. Wells 6407/7-9 S and 6407/7-9 A were drilled by the Songa Delta drilling facility, which will now proceed to a plugging operation on Tune in production licence 190.

Njord North Flank-2 exploration well commences drilling in the Norwegian Se

Faroe Petroleum, the independent oil and gas company focusing principally on exploration, appraisal and production opportunities in Norway and the UK, is pleased to announce the commencement of the Njord North Flank-2 (“NF-2”) exploration well 6407/7-9 S (Faroe 7.5%). The NF-2 prospect is located in Licence PL107C immediately north of the Njord field (Faroe 7.5%). The well will target Middle and Lower Jurassic sandstone reservoirs of the Ile and Tilje formations in a fault-bounded structural closure, with a TD in the Lower Jurassic Åre Formation. If successful, NF-2 could add further reserves and value to the Njord Future Project. The NF-2 exploration well, located in approximately 323 metres of water, is operated by Statoil Petroleum AS (20%) using the Songa Delta drilling rig, with co-venturers ENGIE E&P Norge AS (40%), DEA E&P Norge AS (30%) and VNG Norge AS (2.5%). Results from the well will be announced when drilling operations have been completed.

Minor gas/condensate discovery southwest of the Oseberg South field in the North Sea - 30/11-13

Statoil Petroleum AS, operator of production licence 272, has completed the drilling of wildcat well 30/11-13. The well proved gas/condensate. The well was drilled eight kilometres southeast of the 30/11-8 S (Krafla) discovery and about 27 kilometres south of the Oseberg South facility in the North Sea. The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks (the Tarbert formation). The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks (the Ness formation). The well encountered gas columns at two levels in the top part of the Tarbert formation, a total of 5 and 31 metres, respectively, of which 4 and 22 metres had good to moderate reservoir properties. The secondary exploration target in the Ness formation is aquiferous. The preliminary estimation of the size of the discovery is between one and three million standard cubic metres (Sm3) of recoverable oil equivalents. The discovery will be included in the evaluation of a new field development along with previous discoveries in the area. Data has been collected and samples were taken from the well. Well 30/11-13 was drilled to a vertical depth of 3313 metres below the sea surface and was terminated in the Ness formation. The well is the fourth exploration well in production licence 272. The licence was awarded in the North Sea Awards in 2001. Water depth is 106 metres. The well will be permanently plugged and abandoned. Well 30/11-13 was drilled by the Songa Delta drilling facility, which will continue the drilling campaign by drilling wildcat well 30/11-14 in the same production licence, where Statoil Petroleum AS is the operator.

Minor oil discovery and dry appraisal well southwest of the Oseberg Sør field in the North Sea - 30/11-12 S and 30/11-12 A

Statoil Petroleum AS, operator of production licence 035, is in the process of concluding the drilling of wildcat well 30/11-12 S and appraisal well 30/11-12 A. The wells were drilled two kilometres south of the 30/11-9 A (Askja Øst) discovery, and about 35 km southwest of the Oseberg Sør facility in the North Sea. The objective of well 30/11-12 S was to prove petroleum in three sandstone layers in Middle Jurassic reservoir rocks (the Tarbert formation). The objective of well 30/11-12 A was to delineate in the event a discovery was made in 30/11-12 S. 30/11-12 S encountered a 37-metre oil column in the upper part of the Tarbert formation, of which about 30 metres had good to moderate reservoir properties. Well 30/11-12 A, which was drilled further down on the structure, encountered similar reservoir rocks, but is dry. Preliminary estimates place the size of the discovery at between 0.7 and 2.5 million standard cubic metres (Sm3) of recoverable oil equivalents. The discovery will be included in the evaluation of a new field development, along with other earlier discoveries in the area. Data has been collected and samples have been taken in both wells. Wells 30/11-12 S and 30/11-12 A were drilled to vertical and total depths of 3669 and 3671 metres, respectively, and 3609 and 4144 metres below the sea surface. 30/11-12 S was terminated in the Ness formation and 30/11-12 A was terminated in the Tarbert formation. The wells are the 12th and 13th exploration wells in production licence 035. The licence was awarded in the 2nd licensing round in 1969. Water depth is 110 metres.

Minor gas discovery near the Oseberg field in the North Sea – 30/9-28 S

Statoil Petroleum AS, operator of production licence 104, has completed drilling of wildcat well 30/9-28 S. The well was drilled about 5.5 kilometres west of the Oseberg South field in the central part of the North Sea and 140 kilometres west of Bergen. The primary exploration target was to prove petroleum in Lower and Middle Jurassic reservoir rocks (the Tarbert formation and upper part of the Statfjord group). The secondary exploration target was to prove petroleum in Lower Jurassic reservoir rocks (lower part of the Statfjord group). The well encountered an approx. 20-metre gas column, of which 10 metres were in sandstone with good reservoir quality in the Tarbert formation. The gas/water contact in the Tarbert formation has been estimated at 2870 metres based on pressure data. In the Statfjord group, the well encountered a 12-metre gas column in sandstone with moderate reservoir quality. The gas/water contact was proven at 3506 metres. The secondary exploration target in the lower part of the Statfjord group is aquiferous. Preliminary estimation of the size of the discovery is between one and two million standard cubic metres (Sm3) of recoverable oil equivalents. The discovery will be considered for development as part of the “Oseberg Future Phase 2” project. The well was not formation-tested, but data acquisition and sampling were carried out. This is the 24th exploration well drilled in production licence 104.

New rig for Statoil’s fast-track portfolio

Statoil has awarded Songa Offshore a contract for hire of the semi-submersible rig Songa Delta, for use in the fast-track portfolio on the Norwegian continental shelf (NCS). The contract value is approximately USD 400 million. The rig will carry out production drilling for Statoil’s fast-track portfolio on the NCS. It will be used for drilling and completing wells, and will quickly be able to contribute to the production of the fields. “We will be able to realise small finds that normally would not be profitable through fast-track developments and standardised solutions,” says Ivar Aasheim, head of field development on the NCS. “Securing drilling capacity is vital to be able to execute our fast-track developments. This helps to maintain the production level on the NCS.” Plans call for the rig to start its production assignment for Statoil in the summer of 2012. Jon Arnt Jacobsen, Statoil chief procurement officer, is pleased that the company has acquired future rig capacity. “We are pleased to have secured yet another rig from Songa Offshore. This contract award addresses our ambition to sustain production,” says Jacobsen. “The rig will work specifically for Statoil’s fast-track developments, and will play an important part in maintaining the pace of our fast-track projects.” The contract period is three years firm, and includes a one-year option following the completion of the drilling programme. Statoil has an option to extend the contract period from three to four years firm.
