Dry well northwest of the Ekofisk field in the North Sea - 1/5-5

Total Norge AS, operator of production licence 618, is in the process of completing the drilling of wildcat well 1/5-5. The well is dry. The well was drilled about 40 kilometres northwest of the Ekofisk field and 320 kilometres southwest of Stavanger. The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (Ula formation). The secondary exploration target was to prove petroleum in Upper Triassic reservoir rocks (Skagerrak formation). The well encountered about 80-metre thick sandstone in the Ula formation with moderate to poor reservoir quality. The reservoir only contains traces of gas. The well is classified as dry. Data acquisition was carried out. This is the first exploration well in production licence 618. The licence was awarded in APA 2011. Well 1/5-5 was drilled to a vertical depth of 5942 metres below the sea surface and was terminated in the Bryne formation in the Middle Jurassic. Water depth at the site is 70 metres. The well will now be plugged and abandoned. Well 1/5-5 was drilled with the Maersk Gallant drilling rig.

Mærsk Gallant drills to record depths on Norwegian shelf

With a total depth of 5,941 metres, Mærsk Gallant has beaten the record for deepest well ever drilled on the Norwegian continental shelf. On 31 July, Mærsk Gallant drilled the Solaris ultra HPHT (high-pressure, high-temperature) well to a total depth of 5,941 metres TVD (True Vertical Depth). This means that Mærsk Gallant has beaten the record for deepest well ever drilled on the Norwegian continental shelf. "We have broken a number of records during the Solaris operation. But this achievement is second to none. There was a lot of cheering in the driller's cabin that day," says Sadi Ozturk, Assistant Rig Manager on Mærsk Gallant. He continues: "The Solaris exploration well is one of the most challenging wells in the North Sea. All crew members are very excited about this achievement." In the Solaris project – together with the customer, Total E&P Norge – Maersk Drilling has taken a 15,000 psi rig and adapted the equipment and procedures in order to drill a reservoir section where predicted pore pressures are well in excess of 15,000 psi. The demanding requirements of the customer have led to a wide variety of modifications on the rig.

Statoil announces discovery at Julius

Statoil Petroleum AS, operator of production licence 146, is in the process of concluding the drilling of wildcat well 2/4-23 S. The well was drilled about 17 kilometres northeast of the Ekofisk field, near the 2/4-21 (King Lear) discovery in the southern part of the North Sea. The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (the Ula formation) and Middle Jurassic reservoir rocks (the Bryne formation), as well as to delineate the 2/4-21 discovery (King Lear), which was proven in Upper Jurassic reservoir rocks (the Farsund formation) in the summer of 2012. Before well 2/4-23 S was drilled, the operator's resource estimate for King Lear was between 11 and 32 million standard cubic metres of recoverable oil equivalents. The secondary exploration target for 2/4-23 S was to prove petroleum in Upper Triassic reservoir rocks (the Skagerrak formation). In the primary exploration target, the well encountered 41 metres of gas/condensate-filled sandstone rocks in the Ula formation, with moderate reservoir quality. The petroleum/water contact was not encountered. Preliminary estimates place the size of the discovery at between 2.5 and 12 million Sm3 of recoverable oil equivalents. The well also encountered 30 gross metres of water-filled sandstone with poor reservoir quality in the Bryne formation. In addition, the well encountered a 20-metre thick gas/condensate column in the Farsund formation, in two zones of five metre thick reservoir rocks with moderate/good reservoir quality, which confirmed pressure communication with the 2/4-21 King Lear discovery. Delineation of the 2/4-21 discovery will not lead to any change in the resource estimates. The Skagerrak formation had poor reservoir quality and was water-filled. The well was not formation-tested, but extensive data acquisition and sampling have been carried out. The licensees will assess the discoveries together, with a view toward an optimal development. This is the fourteenth exploration well in production licence 146, which was awarded in the 12th licensing round. Well 2/4-23 S was drilled to a vertical depth of 5548 metres below the sea surface, and was terminated in sandstone in the Skagerrak formation in the Upper Triassic. Water depth at the site is 68 metres. The well will now be permanently plugged and abandoned. Well 2/4-23 S was drilled by the Mærsk Gallant, which will now proceed to PL 018 to do well work on the Eldfisk field in the North Sea.

Statoil discovers oil at Romeo prospect

Statoil Petroleum AS, operator of production licence 146, is in the process of completing the drilling of wildcat well 2/4-22 S. The well was drilled about 20 kilometres north of the Ekofisk field and 2.3 kilometres northeast of the 2/4-21 discovery in the southern part of the North Sea. The primary exploration target for well 2/4-22 S was to prove petroleum in reservoir rocks in the Permian (in the Rotliegend group). The secondary exploration target was to prove petroleum in reservoir rocks in the Middle Jurassic (the Bryne formation). In its primary exploration target, the well encountered a 27-metre total oil column in the Rotliegend group, 24 metres of which was sandstone of good reservoir quality. In its secondary exploration target, the well encountered oil columns in two intervals in the Bryne formation, where the top interval also extends into the overlying Ula formation in the Upper Jurassic. No oil/water contact was encountered in either of the intervals in the Jurassic. The Bryne formation has a 46-metre total oil column, about 30 metres of which is sandstone of good to poor reservoir quality. The Bryne and Ula formations have a 49-metre total oil column, about 15 metres of which are from multiple thin sandstone layers with good to poor reservoir quality. Data acquisition and sampling have been carried out. Preliminary estimates of the size of the discovery range between 0.7 and 2 million Sm3 of recoverable oil equivalents. Further studies are needed in order to determine whether the discovery can be included as part of a future development of the area. This is the ninth exploration well in production licence 146. The license was awarded in the 12th licensing round in 1988. Well 2/4-22 S was drilled to a vertical depth of 4834 metres below sea level and was terminated in the Rotliegend group. Water depth at the site is 67 metres. The well will now be permanently plugged and abandoned. Well 2/4-22 S was drilled by the Maersk Gallant drilling facility, which will now move on to drill exploration well 2/4-23 in the same production licence.

Significant gas and condensate discovery in the North Sea

Statoil has made a significant gas and condensate discovery in the King Lear prospect in the southern part of the Norwegian North Sea along with its partner Total E&P Norge. Exploration well 2/4-21 drilled by the jack-up rig Maersk Gallant in production licences 146 and 333, has proven a 48-metre gas/condensate column in the main bore 2/4-21 and an additional 70-metre gas/condensate column in the side-track 2/4-21A. Statoil estimates the total volumes in King Lear to be between 70 and 200 million barrels of recoverable oil equivalent (o.e.). “Statoil had earlier defined King Lear as a potential high-impact prospect. The drill results confirm our expectations and show once again that the Norwegian continental shelf still delivers high value barrels,” says Gro Gunleiksrud Haatvedt , senior vice president exploration Norway in Statoil. Data acquisition is currently being finalised in the sidetrack. As King Lear is a high-pressure, high-temperature well, special attention is given to ensuring safe drilling operations. The King Lear discovery is an important contribution to Statoil’s corporate strategy of revitalising the NCS with high-value barrels. “King Lear lies approximately 20 kilometres north of the Ekofisk field. It is encouraging to see that this part of the Norwegian continental shelf – home to the first commercial oil find in Norway – is still delivering significant discoveries,” says Haatvedt. “This reinforces our faith in the exploration potential of the Norwegian continental shelf. Not only does it have a proud past, but also an exciting future,” she adds. Statoil will plan for appraisal drilling of the discovery as well as exploration drilling on other interesting prospects in the licences. Going forward, Statoil as operator will look into an optimal development solution for King Lear and evaluate if the discovery should be developed as a stand-alone or as a tie-in to infrastructure in the area. This area, normally considered an oil province, may on the basis of this discovery and other gas resources form the basis for future gas development. Wells 2/4-21 and 2/4-21 A are the eleventh and twelfth wells drilled in production licence PL146. Well 2/4-21 was drilled to a vertical depth of 5,344 metres below sea level in 67 metres of water, while well 2/4-21 A was drilled to a vertical depth of 5,237 metres below sea level. Statoil is operator for production licences PL146 and PL333 with an ownership share of 77.8%. The licence partner is Total E&P Norge (22.2%). The King Lear discovery is the eighth high-impact* discovery made by Statoil over the last 15 months. The other high-impact discoveries are Zafarani and Lavani 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.
