Minor oil discovery near the Vega field in the North Sea – 35/11-19 S, 35/11-20 S, 35/11-20 A and 35/11-20 B

Wintershall Norge AS, operator of production licence 248 F, is in the process of completing the drilling of four wells in the North Sea. The wells are wildcat well 35/11-20 S, appraisal well 35/11-20 A and wildcat well 35/11-20 B. Due to technical issues, well 35/11-19 S had to be abandoned, and well 35/11-20 S was drilled about 50 metres southwest of 35/11-19 S. Well 35/11-20 A was classified as a wildcat well, but will now be reclassified as an appraisal well. The wells were drilled about five kilometres southeast of the Vega field in the North Sea and 100 kilometres southwest of Florø. The primary and secondary exploration targets for well 35/11-20 S were to prove petroleum in Late Jurassic reservoir rocks (intra Heather formation sandstone). The well did not encounter reservoir rocks in the primary exploration target. The well encountered an 8-metre oil column in the secondary exploration target at the top of an intra Heather formation sandstone with poor reservoir quality and a total thickness of about 70 metres. The objective of well 35/11-20 A was to delineate the oil discovery in intra Heather formation sandstone, and to prove petroleum in Middle Jurassic (Brent group) and Early Jurassic (Cook formation) reservoir rocks. The well encountered a total oil column of 33 metres in intra Heather formation sandstone, of which 19 metres were of good reservoir quality. Due to technical issues, it was not possible to reach the Brent group and Cook formation. Well 35/11-20 B was drilled to further delineate the oil discovery in intra Heather formation sandstone. The secondary target was to prove petroleum in Middle Jurassic (Brent group) and Early Jurassic (Cook formation) reservoir rocks. The well encountered a total oil column of 46 metres in intra Heather formation sandstone, of which 29 metres were of moderate reservoir quality. A total oil column of 19 metres was encountered in the Tarbert formation in the Brent group, of which 10 metres were of moderate reservoir quality. The Cook formation was encountered with a total thickness of about 170 metres with predominantly poor reservoir quality and only traces of petroleum. Preliminary estimates place the size of the discovery between 1.5 and 4.5 million standard cubic metres (Sm3) of recoverable oil equivalents. The licensees will evaluate the discovery along with other nearby discoveries with a view toward a potential development. The wells have not been formation-tested, but extensive data and samples were collected. The wells are the second, third, fourth and fifth exploration wells in production licence 248 F. Wells 35/11-20 S and 35/11-20 A were drilled to respective measured depths of 3553 and 3943 metres below the sea surface and respective vertical depths of 3437 and 3293 metres below the sea surface. Both wells were terminated in the Heather formation in the Middle Jurassic. Well 35/11-20 B was drilled to measured and vertical depths of 5083 metres and 4055 metres below the sea surface, respectively, and was terminated in the Statfjord group in the Early Jurassic. Water depth at the site is 373 metres. The wells will now be permanently plugged and abandoned. Wells 35/11-19 S, 35/11-20 S, 35/11-20 A and 35/11-20 B were drilled by the Borgland Dolphin drilling facility.

Wintershall Norge AS, operator of production licence 248, is in the process of completing the drilling of wildcat well 35/11-18 and appraisal well 35/11-18 A. The wells have been drilled approx. four kilometres west of the Vega Sør field. The primary exploration target for well 35/11-18 was to prove petroleum in Middle Jurassic reservoir rocks (the Brent group). The secondary exploration target was to prove petroleum in Upper Jurassic reservoir rocks (sandstones in the Heather formation). In the primary exploration target, the well encountered a 275 metre thickness of moderate to good reservoir quality in the Brent group. The well proved light oil in the Tarbert and Oseberg formation, with columns of eleven and three metres, respectively. In the secondary exploration target, the well encountered an eight-metre hydrocarbon column of good to poor reservoir quality. The objective of appraisal well 35/11-18 A was to investigate the extent of the reservoir and the hydrocarbon columns. The well was drilled about 450 metres south of the discovery well. The well proved gas and oil in two Upper Jurassic (the Heather formation) sandstones with net thicknesses of 33 and 24 metres, respectively, with poor to good reservoir quality. The well encountered oil throughout the Brent group, which is 270 metres, with moderate to good reservoir quality. The well also encountered a 46-metre column of light oil in the Lower Jurassic (the Cook formation). Preliminary estimates place the size of the discovery between 1 and 3 million Sm3 of recoverable oil. Extensive data collection and sampling have been carried out, including two formation tests in the Cook and Oseberg formation in 35/11-18 A. The tests show good flow properties with stable flow pressure and low pressure drop, with good permeability. The wells are the second and third exploration wells in production licence 248. Well 35/11-18 was drilled to a measured depth of 3759 metres below the sea surface (3709 metres vertical depth) and was terminated in Early Jurassic rocks (the Cook formation).

Wintershall concludes appraisal well drilling near Tyrihans field in Norwegian Sea

Wintershall Norge AS, operator of production licence 475, has concluded the drilling of appraisal wells 6407/1-7 and 6407/1-7 A. The wells were drilled about eight kilometres northeast of the Tyrihans field and five kilometres northeast of the 6407/1-6 S gas condensate discovery in production licence 475. The reservoir in this discovery consists of thin sandstone layers from the Lange formation in the Lower Cretaceous. The discovery was made in January 2013. The resource estimate for the discovery was then between 3 and 20 million Sm3 of recoverable oil equivalents. The objective of well 6407/1-7 was to delineate the 6407/1-6 gas/condensate discovery higher up in the structure. A new appraisal well, 6407/1-7 A, was therefore drilled downflank to investigate reservoir thickness and lithology. Well 6407/1-7 proved gas/condensate in two sandstone intervals with a net vertical thickness of 12 metres and a gross reservoir thickness of 16 metres. Well 6407/1-7 A proved gas/condensate in two sandstone intervals with a vertical thickness of seven metres and a gross reservoir thickness of 13 metres. The difference in pressure measurements between wells 6407/1-7, 6407/1-7 A and the discovery well 6407/1-6 S indicates that there is no communication between the appraisal wells and the 6407/1-6 S discovery. Well 6407/1-7 has therefore proven a separate discovery, and will be reclassified as a wildcat well. Preliminary estimates of the size of the new gas/condensate discovery range from 1 to 4 million Sm3 of recoverable oil equivalents. The resource estimate for the 6407/1-6 S gas/condensate discovery has now been downgraded to between 1 and 6 million Sm3 of recoverable oil equivalents. The licensees will consider the discoveries in conjunction with other nearby discoveries as regards future development. This is the second and third exploration well in production licence 475. The production licence was awarded on 29 February 2008 (APA 2007). Wells 6407/1-7 and 6407/1-7 A were drilled to vertical depths of 3345 and 3311 metres, respectively, below the sea surface, the latter with a measured depth of 3571 metres. Both wells were terminated in the Lange formation in the Early Cretaceous. Water depth at the site is 280 metres. The well has been permanently plugged and abandoned. Wells 6407/1-7 and 6407/1-7 A were drilled by the Borgland Dolphin drilling facility, which will now proceed to production licence 550 in the northern part of the North Sea to drill wildcat well 31/2-21 S, where Tullow Oil Norge AS is the operator.

Further delineation of the Pan/Pandora find

StatoilHydro is currently completing the drilling of two appraisal wells in the Pan/Pandora find south of the Visund field in the North Sea. Drilling of appraisal well 34/8-14 C has been completed, whereas drilling of well 34/8-14 D is presently being completed. The Pan/Pandora gas and oil find has earlier been delineated in the northern segment. The find was confirmed in October 2008 during drilling of exploration well 34/8-14 S. The purpose of well 34/8-14 C was to confirm the oil/water contact in the northern part of the Pan/Pandora find. The purpose of well 34/8-14 D was to delineate the find in the eastern direction. The well confirmed gas and oil columns indicating concurrent hydrocarbon contacts as observed in the original discovery well. The wells have not been formation tested, but data acquisition and sampling have been carried out. "The area south of Visund has a considerable remaining resource potential, says Alfred Båtevik, StatoilHydro's team leder for exploration activities in the Tampen area. "The resources confirmed in the Pan/Pandora find are estimated at between 22 and 47 million barrels of recoverable oil equivalent." Developing the find and connecting it to the Visund field is being considered. Well 34/8-14 C was drilled to a vertical depth of 3,008 metres below sea level and completed in mid-Jurassic rocks. Well 34/8-14 D was drilled to a vertical depth of 2,941 metres below sea level and completed in lower Jurassic rocks. Located at a water depth of 292 metres the wells will be permanently plugged and abandoned. Drilling has been performed by the Borgland Dolphin rig. The rig will move to production licence PL089 in the North Sea to drill the 34/7-34 exploration well, which is also operated by StatoilHydro. Licensees in production licences 120 and 120B are: StatoilHydro (operator) (59.06%), Petoro (16.94), ConocoPhillips (13) and Total (11).

Delineation of North Sea oil and gas discovery

StatoilHydro has completed the drilling of an appraisal well on the Pan/Pandora gas/oil discovery south of the Visund field in the North Sea. The purpose of well 34/8-14 A was to delineate the 34/8-14 S Pan/Pandora discovery in the northern segment of this structure. "The area south of Visund has a considerable remaining resource potential, and we are very pleased that the expectations as to the northern extension of the discovery now have been confirmed," says the head of infrastructure-led exploration west, May-Liss Hauknes. The well confirmed the existence of a 53-metre gas column over an eight-metre oil column in the Brent group. Extensive data acquisition and sampling have been conducted. StatoilHydro will drill a sidetrack from this appraisal well. Well 34/8-14 C will be drilled in the lower flank of the same segment. The sidetrack is designed to determine the oil/water contact and contribute to more accurate evaluations of the Pan/Pandora resource potential. This is the 14th exploration well in production licence 120, which was awarded in 1985. The appraisal well was drilled to a vertical depth of 3,044 metres below the sea level and completed in the Drake formation in Lower Jurassic reservoir rocks. Drilled in 292 metres of water the well will now be permanently plugged and abandoned. The drilling was performed by the Borgland Dolphin drilling rig, which will now drill the 34/8-14 C sidetrack as part of PL 120 operations. The partners in production licences 120 and 120B are: StatoilHydro (operator) (59.06 percent), Petoro (16.94 percent), ConocoPhillips (13 percent) and Total (11 percent).

Borgland Dolphin chartered for Tampen

Rig capacity for recovering more oil from the mature Tampen area of the North Sea has been secured by Statoil through a three-year charter for the Borgland Dolphin drilling rig. Placed with rig contractor Dolphin, owned by Norway’s Fred Olsen shipping group, this contract will commence on 1 January 2007 and is worth some NOK 2.3 billion. The semi-submersible unit will be used for drilling and well operations on such developments as the Statfjord and Gullfaks satellites, the Tordis, Vigdis and Borg subsea fields and Visund. Borgland Dolphin will have operated for six years in the Tampen area at the end of December, reports Øyvin Jensen, manager of drilling and subsea operations for this part of the North Sea. “It’s important for us and our partners that we secure continued access to this rig for on-going drilling and well work,” he explains. “These activities embrace both exploration and production drilling in the Tampen area over the next three years.”

Wildcat on Verdandi

The first exploration well on Statoil's Verdandi prospect in block 16/1 of the North Sea was spudded today, 22 May. The block lies about 25 kilometres south-west of Norsk Hydro's Grane field. "We are primarily looking for oil in this well," says Øivind Dahl-Stamnes, sector manager in the exploration Norway business cluster. He adds that there is much uncertainty about the possibility for a discovery in Verdandi, as is always the case in new prospects. The drilling operation is being performed by the Borgland Dolphin rig and is expected to take one month. As operator, Statoil is carrying out the drilling on behalf of licence 167. The licensees are Det norske oljeselskap (20 per cent) and Statoil (80 per cent). The block was awarded in the 13th licensing round in 1991.

Dolphin dispute resolved

An amicable solution has today, 3 February, been reached between Statoil and Dolphin in the dispute over responsibility for cost overruns in connection with the modification of the Borgland Dolphin drilling rig. The settlement entails Statoil paying Dolphin NOK 75 million in compensation. Dolphin is a wholly-owned subsidiary of Fred. Olsen Energy. Statoil and Dolphin are pleased to be able to put this dispute behind them and focus instead on further cooperation.

Two finds on Tampen

Operator Statoil has proven gas condensate and light oil in two wells drilled close to the Gullfaks and Statfjord fields in the North Sea. Exploration well 33/12-8S was drilled in the Dole prospect, while well 33/12-8A was drilled in the Ole prospect. Both wells lie in production licence 152. Hydrocarbons were proven in Middle Jurassic rocks in the wells. Due to similarities with the Rimfaks and Gullveig producing fields, the wells were not production tested. Well 33/12-8S was drilled to 3,350 metres below mean sea level, and 33/12-8A was drilled to 3,369 metres. The latter was temporarily abandoned and will come on stream at a later stage. Both wells were drilled with the Borgland Dolphin rig. “We have started a project to evaluate potential tie-back points for the new finds. If they are profitable, we expect them to produce from 2004,” reports Bengt Beskow, exploration manager for the Tampen area. The finds lie about 16 kilometres from both the Statfjord B platform and the Gullfaks A platform. The distance between Ole and Dole is around 1,700 metres. Two development alternatives are being evaluated. The finds could be tied back via subsea templates on the Gullfaks South satellite field and then on to Gullfaks C, or they could be tied back to the Statfjord B platform. Statoil will be the sole operator for the Tampen area when the group takes over Snorre, Visund, Vigdis and Tordis from Norsk Hydro on 1 January 2003. The group therefore wants to search for and develop small finds in the area in order to extend production from the Tampen platforms. The licensees in production licence 152 are Statoil (58.89 per cent), Petoro (30 per cent) and ExxonMobil (11.11 per cent). Statoil has entered into an agreement to take over ExxonMobil’s stake with effect from 1 January 2002. The agreement is expected to be approved by the authorities before the summer.

Exploration well on Tampen

The Borgland Dolphin drilling rig is drilling an exploration well for Statoil south of the Gullfaks satellite Gullveig in the Tampen area of the North Sea. Well 33/12-8S is being drilled in production licence 152, which lies in the Dole structure about four kilometres south of the Gullveig field. If a find is made, a sidetrack to the south into the neighbouring Ole structure may be an option, reports Eirik Graue, project manager for the drilling. The purpose of the well is to prove hydrocarbons in the Brent and Statfjord reservoirs; the former lies 2,600 metres below the seabed while the latter lies 600 metres deeper. Plans call for drilling to be completed by the beginning of May. Statoil’s exploration programme in the area includes a well in a structure named N7-Dolly, about four kilometres north of Gullveig. Plans call for this well to be drilled in late autumn.

Rig move from Norne to Svale

Yesterday, 7 August, the drilling rig Borgland Dolphin was moved 10 kilometres from the Norne field in the Norwegian Sea to the Svale structure. “We are going to retrieve some measuring instruments that were left in the first well, 10-6,” reports Kjell Sirnes, project manager for Svale. At the same time, Statoil will test the production properties in the reservoir and confirm the reserves. If the test is successful and the volumes are confirmed, the plan is to develop the reservoir. The Svale structure was proven in May 2000. The field may be developed as a satellite tied back to the production ship on the Norne field. Both Norne and Svale lie in production licence 128, about 175 kilometres off northen Norway. Rig operations on Svale are estimated to last three to four weeks. Borgland Dolphin will then return to Norne to prepare a well for seawater injection.

Oil find in Svale

Statoil has proven oil in an appraisal well drilled in the Svale structure in the Norwegian Sea. The find confirms previous reserve estimates and can strengthen the case for development of this reservoir. Project manager for Svale, Kjell Sirnes, says that the intention of the well, which proved oil in a Jurassic sandstone layer, was to help determine the extent of the reservoir and its flow properties. “We’ve taken core samples and carried out extensive logging of the well. The results, which will be available in one month, will form the basis for a new evaluation of the reserves in the structure,” he says. The Svale structure was proven in May 2000. Plans calls for the development of Svale as a satellite linked to the production ship on the Norne field. Well 6608/10-7 was drilled by the Borgland Dolphin rig. The Norne field and the Svale structure lie in production licence 128, about 175 kilometres off the coast of mid-Norway.

Ready to spud well 1000

The drilling rig Borgland Dolphin is ready to start drilling exploration well number 1000 on the Norwegian continental shelf some time this weekend. The well will be drilled on the Svale field near Norne in the Norwegian Sea. Appraisal well 6608/10-7 in production licence 128 will be drilled on behalf of the operator Statoil. Drilling is scheduled to take 55 days. Sector manager Roger Inge Johansen at the Harstad office of Exploration & Production Norway says that the objective is to survey the chemical composition in the water zone and confirm the reserves in the Svale field. In order to clarify this, it is necessary to drill quite deep into the reservoir, towards the areas where the oil comes into contact with water. Project manager for Svale, Kjell Sirnes, says that depending on the results of the drilling, the licence group will consider submitting a plan for development and operation at the end of the year. The plan is to develop the deposits as a satellite linked to the production vessel on the Norne field. Production could start towards the end of 2003, provided that the authorities give their approval. Statoil has a 40 per cent share in production licence 128. The other licensees are the state’s direct financial interest (25 per cent), Norsk Hydro (13.5 per cent), Norsk Agip (11.5 per cent) and Enterprise Oil (10 per cent).
