The well is located about 16 miles (25 kilometers) east of the Luno discovery, on the opposite side of the Utsira structural high. The target is a Lower Cretaceous/Jurassic age sandstone sequence, analogous to the Luno reservoir, within a combined stratigraphic/four-way-dip closure.

In September 2010, a discovery was made in the Avaldsnes prospect. The well's primary exploration target was to prove petroleum in Upper Jurassic reservoir rocks in the Hugin formation, while the secondary target was to prove petroleum in reservoir rocks in the Lower Paleocene in the Ty formation. Drilled to a vertical depth of 6,995 feet (2,132 meters), the well terminated in the Zechstein group in the Upper Permian section.

Oil was proven in a 56-foot (17-meter) column in the Draupne and Hugin formation in the Upper to Middle Jurassic, while the Ty formation lacked reservoir formation. A formation test was performed, showing very good flow properties.

The operator appraised the find in August 2011. The second appraisal well, 16/2-7, confirmed the continuation of the Avaldsnes field about 3 miles (5.5 kilometers) south of the 16/2-6 discovery well and 2.7 miles (4.5 kilometers) southwest of the first appraisal well 16/3-4.

The second well encountered a large reservoir column of excellent-quality Upper Jurassic age sandstone of about 115 feet (35 meters), of which 23 feet (7 meters) were above the oil water contact. The operator performed a coring and logging program that confirmed the well has excellent quality reservoir characteristics.

The sidetrack well encountered a gross reservoir column of about 82 feet (25 meters) of which 56 feet (17 meters) net was above the oil water contact. The operator conducted a coring and logging program, confirming that the reservoir has similar characteristics to the Avaldsnes discovery and appraisal wells.

Aldous

The Aldous field is located on Block 16/2 in Production License 265 in the Norwegian sector of the North Sea. Statoil operates Production License 265 with a 40% interest; Petoro with 30%; Det norske with 20%; and Lundin with 10%.

Statoil made a discovery in well 16/2-8, finding a 213-foot (65-meter) oil column in Jurassic sandstones. Statoil said the acquired data has confirmed that this is a reservoir of excellent quality.

Preliminary volumes are estimated at between 200 and 400 million barrels of oil equivalent for this part of the structure in PL 265, and the operator expects additional upside in the license both north and south of the discovery. Well 16/2-8 indicates the same oil-water contact as in the Avaldsnes discovery well, suggesting the likelihood of communication between the two structures.

In early 2012 the Avaldsnes/Aldous discovery was renamed Johan Sverdrup. Following an appraisal drilling program, the Johan Sverdrup structure is estimated to contain between 1.7-3.3 billion boe of gross recoverable resources making it the largest discovery on the NCS since the mid-eighties. Appraisal and exploration activities during 2012 will further prove the Johan Sverdrup area.

Lunding Successfully Appraises Eastern Portion of Johan Sverdrup
Type: Appraisal Operations

Mar. 2014 - Lundin Petroleum recently completed appraisal well 16/3-8S in license PL501 on the eastern portion of the Johan Sverdrup discovery. The well was drilled to investigate the thickness and quality of the late Jurassic Draupne sandstone reservoir as well as the Permian Zechstein carbonates. At this location, the Draupne sands proved to be of excellent quality and yielded 42 feet of oil pay. During a production test, the interval flowed at a rate of 4,900 bopd through a 52/64" choke. Additionally, a sidetrack was drilled to examine the petrophysical properties of the reservoir and that data is being analyzed. Both wells were drilled by the Bredford Dolphin (mid-water semisub).

Phase 1 Development Concept Chosen for Johan Sverdrup
Type: Development Activity

Feb. 2014 - The Johan Sverdrup joint venture partners agreed to a concept for the first phase of development of the giant field. Johan Sverdrup covers sections of licenses PL265, PL501 and PL502 in the Norwegian North Sea. With gross recoverable contingent resources ranging between 1.8 and 2.9 Bboe, Johan Sverdrup is one of the five largest fields to be discovered on the Norwegian continental shelf and could one day account for as much as 25% of all Norwegian oil production. Phase 1 will be centered around 4 fixed platforms, with associated subsea installations consisting of a processing platform, riser platform, wellhead platform with drilling facilities and a living quarters platform. The development will go online in 2019 with a gross production capacity between 315,000 and 380,000 boepd supported by 40 to 50 production and injection wells. Gross capital Phase 1 investment is estimated at $16.5 to $19.5 billion. A plan of development will be submitted to Norwegian authorities in early 2015.

Lundin Completes, Tests Johan Sverdrup Appraisal Well
Type: Appraisal Operations

Mar. 2012 - Lundin Petroleum announced that the Johan Sverdup appraisal well 16/2-11 encountered a 177-foot (54-meter) gross oil column in Upper and Middle Jurassic sandstone reservoir in an oil-down-to situation. A comprehensive logging and coring program was successfully completed as well as a production test in the previously untested Middle Jurassic reservoir. The data from this first well in the 2012 PL501 appraisal program confirmed good reservoir properties. This is in line with the earlier Johan Sverdup wells where the Upper Jurassic reservoir was of excellent quality with a high net to gross ratio. A full scale production test (DST) in the Middle Jurassic reservoir to investigate its flow properties resulted in flow rates, in excess of 2,700 bopd through a restricted 40/64 choke, with good reservoir properties indicating a lateral continuous reservoir. Lundin will now sidetrack the well towards the east to investigate the lateral thickness and property variations of the Jurassic reservoir as well as establish an oil water contact to investigate the possibility of a deeper oil-water-contact in this area.

Lundin Spuds Johan Sverdup Appraisal Well

Feb. 2012 - Lundin Petroleum has commenced appraisal drilling at well 16/2-11 on the Johan Sverdup discovery located in the Norwegian sector of the North Sea. The planned total depth is 7,136 feet (2,175 meters) and the well will be drilled by the Bredford Dolphin (mid-water semisub). Drilling operations are estimated to take 40 days. The objective of the well is to determine the thickness and quality of an oil bearing Jurassic sequence at the appraisal well location. The well is located 1.3 miles (2,2 kilometers) south east from the Johan Sverdrup PL265 discovery well 16/2-8.

Lundin Likely to Reduce Current Resource Estimates for Avaldsnes
Type: Appraisal Operations

Jan. 2012 - Lundin Petroleum has completed the 16/5-2S Avaldsnes appraisal well, located about 5.2 miles (8.5 kilometers) south of the discovery well 16/2-6 and two miles (four kilometers) south of the appraisal well 16/2-7. The objective of well 16/5-2S was to delineate the southern flank of the Avaldsnes discovery. Well 16/5-2S encountered a 49-foot (15-meter) Jurassic sequence of which the upper 26 feet (8 meters) has excellent reservoir quality. The top of the reservoir is deeper than expected, and below the oil water contact. Good hydrocarbon shows were observed below the oil water contact but were evaluated as not producable hydrocarbons. A comprehensive data acquisition program was performed, which including coring, wireline logging and fluid sampling. Results from the well will be incorporated into the current reservoir model, and a revised resource estimate will be released after the completion of the next appraisal well, 16/2-11. Well 16/5-2S is the first of an extensive Avaldsnes appraisal program compromising at least four wells in PL 501 during 2012. Lundin says this campaign will address key development planning uncertainties to ensure an efficient and optimal field development process for this discovery. The well was drilled to a total depth of 6,699 feet (2,042 meters) in a water depth of 364 feet (111 meters).

Lundin Spuds Third Appraisal Well on Avaldsnes

The objective of the well is to appraise the discovery following the 16/2-6 discovery well in 2010 and the appraisal wells 16/3-4 and 16/2-7, drilled earlier this year. Lundin has estimated the discovery holds gross contingent recoverable resources at between 900 MM to 1.5 B barrels of oil. In total, the Avaldsnes/Aldous Major South discovery is estimated to contain gross contingent recoverable resources of 1.7 to 3.3 billion barrels. Avaldsnes is located on Block 16/2 in 377 feet (115 meters) of water. Lundin serves as operator of Production License 501 with a 40 percent interest. Partners on the license include Statoil with 40 percent and Maersk Oil with 20 percent.

Statoil Plugs Delineation Well on Aldous Major South
Type: Status Update

Oct. 2011 - Statoil is nearing completion of a delineation well in Production License 265. The primary exploration target for well 16/2-10 was to delineate the discovery, which confirmed the extension towards the north. The secondary exploration target was to determine the reservoir quality and petroleum in the Upper Cretaceous and Upper Triassic age. Well 16/2-10 encountered a 213 feet (65-meter) oil column in Upper to Middle Jurassic reservoir rocks, and determined that the oil/water contact is about 44 feet (13.5 meters) deeper than the previous 16/2-8 and 16/2-6 wells. The operator stated that the reservoir is thicker than expected and of good quality. Furthermore, the well encountered rocks with very limited reservoir quality and without petroleum in the secondary exploration targets. A formation test was not performed, but a comprehensive data acquisition and sampling took place. Drilled by the Transocean Leader semisub, well 16/2-10 reached a vertical depth of 6,775 feet (2,066 meters) and terminated in the Skagerrak formation in Upper Triassic. The well will be permanently plugged and abandoned. Statoil operates the license with a 40 percent interest; Petoro with 30 percent; Det norske with 20 percent; and Lundin Petroleum with 10 percent.

Statoil Confirms Aldous Major South Extends to the North
Type: Status Update

Oct. 2011 - Statoil and partners have confirmed that the Aldous Major South structure extends to the north. The 16/2-10 appraisal well encountered an oil column of 164 to 184 feet (50 to 55 meters) in sandstone of Jurassic age, confirming Statoil's preliminary estimate of 400 to 800 million bbl of oil equivalent recoverable on the structure in Production License 265. Statoil will update the contingent resource range once the data from this appraisal well is analyzed. As previously reported, the Aldous Major South discovery is an extension of the Avaldsnes discovery made by Lundin Petroleum in PL 501. Lundin also recently updated its gross contingent resource estimate for the Avaldsnes discovery within PL 501 to be 800 million to 1.8 billion bbl of recoverable oil. In total, the gross contingent resources for the Avaldsnes/Aldous Major South discovery is estimated to be 1.2 to 2.6 billion barrels of recoverable oil.

Lundin Increases Avaldsnes' Recoverable Oil Resources
Type: Operator Update

Sep. 2011 - Lundin Petroleum has increased the estimate of recoverable oil resources at the Avaldsnes discovery to 800 to 1.8 MMbbl within license PL 501. The operator said this estimate follows the results from two appraisal wells and a sidetrack program. This estimate is also based on the Aldous Major South discovery drilled by Statoil in the adjoining license PL 265. The Avaldsnes discovery well 16/2-6 and the appraisal well 16/3-4 were both tested and proved high lateral continuity and productivity of the main Upper Jurassic reservoir sands. The wells have confirmed excellent reservoir properties. Lundin states that the appraisal wells have significantly upgraded the thickness and properties of the main prime Volgian Upper Jurassic reservoir, which has had a material impact upon the revised recoverable resources. Additionally, it is now believed that the Upper Jurassic Volgian reservoir is transgressive across the whole of the Avaldsnes structure. Statoil, as operator for PL 265, has announced an estimated recoverable resource range from 400 to 800 million barrels for Aldous Major South. The combined Avaldsnes/Aldous Major South discoveries have a gross contingent resource range estimate of 1.2 to 2.6 Bbbl recoverable. Lundin plans to further appraise the field to define the recoverable resource range and to assist with the development planning strategy. Well 16/5- will be drilled in the southwestern part of the Avaldsnes discovery in fourth quarter 2011. The company also plans to drill at least three additional appraisal wells in 2012. Avaldsnes is located on Block 16/2 in 377 feet (115 meters) of water. Lundin serves as operator of Production License 501 with a 40% interest. Partners on the license include Statoil with 40% and Maersk Oil with 20%.

Type: Appraisal Operations

Sep. 2011 - Lundin Petroleum has confirmed that the Avaldsnes appraisal well (16/2-7A) found an excellent quality oil-bearing Upper Jurassic sandstone reservoir. The sidetrack well encountered a gross reservoir column of about 82 feet (25 meters) of which 56 feet (17 meters) net was above the oil water contact. The operator conducted a coring and logging program, confirming that the reservoir has similar characteristics to the Avaldsnes discovery and appraisal wells. Drilled by the Bredford Dolphin semisub, the well reached a total depth of 6,890 feet (2,100 meters) in a water depth of 371 feet (113 meters). Lundin operates the license with a 40% interest. Partners in the license include Statoil (40%) and Maersk Oil (20%).

Statoil Disappointed with Aldous Major North Results
Type: Operator Update

Sep. 2011 - Statoil and partners have made a small oil discovery in the Aldous Major North prospect, in the Norwegian sector of the North Sea. The operator drilled the well to appraise the size of the Aldous Major North propsect, which, combined with the Aldous Major South and Avaldsnes discoveries, the company believes may hold between 500 MM and 1.2 B of recoverable barrels of oil equivalent. Samples taken from well 16/2-9S found a column of oil of up to 26 feet (eight meters) in formations dating from the Upper Jurassic period. Statoil said that due to the poor reservoir quality, the partnership will consider further exploratory drilling on Aldous Major North in order to clarify the structure’s potential. Drilled by the Transocean Leader semisub, well 16/2-9S lies about 7 miles (12 kilometers) north of the Aldous Major South oil discovery. Aldous Major North and Aldous Major South are two separate structures in the PL 265 license. Following completion of well 16/2-9S on the Aldous Major North prospect, Transocean Leader will return to Aldous Major South to drill appraisal well 16/2-10. Statoil operates the license with a 40% interest; Petoro with 30%; Det norske with 20%; and Lundin Petroleum with 10%.

Statoil Classifies Aldous/Avaldsnes as a Major Discovery in North Sea
Type: Status Update

Aug. 2011 - Statoil has confirmed that communication exists between the Aldous and Avaldsnes oil discoveries in the Norwegian sector of the North Sea. It is estimated that combined, these discoveries may represent an oil structure of between 500 million and 1.2 billion barrels of recoverable oil equivalent. The company stated that if the upper part of the interval strikes pay dirt, the discovery will be one of the 10 largest oil finds ever made on the Norwegian Continental Shelf. Statoil plans to spud the Aldous Major North well 16/2-9 in PL 265 to define additional potential and any connection with Aldous/Avaldsnes. The partners also plan to further appraise PL 265 next year to clarify the full volume capacity for a future development solution.

Statoil Hits Additional Pay in PL 265
Type: New Discovery

Aug. 2011 - Statoil and partners have made an oil discovery on the Aldous Major South prospect in the Norwegian sector of the North Sea. Drilled by the Transocean Leader semisub, the well 16/2-8 found a 213-foot (65-meter) oil column in Jurassic sandstones. Statoil said the acquired data has confirmed that this is a reservoir of excellent quality. Preliminary volumes are estimated at between 200 and 400 million barrels of oil equivalent for this part of the structure in PL 265, and the operator expects additional upside in the license both north and south of the discovery. Well 16/2-8 indicates the same oil-water contact as in the Avaldsnes discovery well, suggesting the likelihood of communication between the two structures. Statoil will update its total resource estimate for the area when the wells are completed and the data analyzed. Aldous Major South is located west of the Avaldsnes discovery, where Statoil has a 40% stake, and some 22 miles (35 kilometers) south of the Statoil-operated Grane field. Statoil operates License PL 265 with a 40% interest; Petoro holds 30%; Det norske holds 20%; and Lundin holds 10%.

Lundin Spuds Avaldsnes Appraisal well
Type: Appraisal Operations

Jul. 2011 - Lundin Petroleum has commenced appraisal drilling on well 16/2-7 on the Avaldsnes discovery located in the Norwegian sector of the North Sea. The planned total depth of the well is 7,464 feet (2,275 meters) and the Bredford Dolphin semisub will drill the well. Drilling operations should take about 55 days. The objective of the well is to assess the Avaldsnes discovery following the 16/2-6 discovery well in 2010 and the recent successful appraisal well 16/3-4 with sidetrack 16/3-4A. Lundin serves as operator of Production License 501 with a 40% interest. Partners on the license include Statoil with 40%, and Maersk Oil with 20%.

Type: Drilling Operations

Jul. 2011 - Statoil has commenced appraisal drilling on well 16/2-8 in the Aldous Major South structure, located in license PL 265, in the Norwegian sector of the North Sea. The operator believes the Aldous Major South structure is a western continuation extension of the Avaldsnes discovery in PL 265. The well is primarily targeting sandstone of Upper and Middle Jurassic age with secondary targets being the Cretaceous Shetland Group chalk and the Triassic Skagerrak formation. The Transocean Leader semisub is drilling the well with duration of about 45 days. The well has a planned total depth of about 6,841 feet (2,085 meters). Statoil operates License PL 265 with a 40% interest; Petoro holds 30%; Det norske holds 20%; and Lundin holds 10%.

Lundin Completes Avaldsnes Sidetrack
Type: Status Update

Jul. 2011 - Lundin Petroleum has completed a sidetrack well, 16/3-4A, on the first appraisal well (16/3-4) on the Avaldsnes discovery in PL 501. The well reached a vertical depth of 6,345 feet (1,934 meters) by the Bredford Dolphin semisub. The objective of the well was to confirm lateral reservoir continuity and sand quality to the west of the first appraisal well. Lundin stated that results from the sidetrack well have shown good lateral continuity of the reservoir, with a proved oil column in excess of 13 feet (4 meters) with excellent quality sands.

PSA Grants Statoil Approval to Drill in PL 265
Type: Status Update

Jul. 2011 - The Petroleum Safety Authority granted Statoil permission to drill two exploratory wells on the Aldous Major and Aldous North prospects in the Norwegian sector of the North Sea. The consortium believes that the Aldous wells are an extension of Lundin's discovery on Avaldsnes in 2010. The wells, 16/2-8 and 16/2-9S, are two-of-four planned wells in the area in 2011, to define the discoveries in both PL 265 and Avaldsnes. Statoil will use the Transocean Leader semisub to drill the wells. Statoil operates Production License 265 with a 40% interest; Petoro with 30%; Det norske with 20%; and Lundin with 10%.

Lundin Confirms Avaldsnes Extension
Type: New Discovery

Jun. 2011 - Lundin Petroleum confirms the 16/3-4 appraisal well proves the Avaldsnes field extends to the southeast of the 16/2-6 discovery well in the Norwegian sector of the North Sea. The operator successfully tested the well and performed a comprehensive logging and coring program. Lundin discovered Avaldsnes through the 16/2-6 well in 2010; and the appraisal well proved an oil column of 44 feet (13.5 meters) in excellent quality sandstone of Jurassic age. A high net-to-gross resulted in net pay at the appraisal location in excess of that at the discovery well. The gathered data confirms excellent reservoir properties, with average porosity of about 30% and multi-Darcy permeability. The well flowed at a rate of 5,500 boepd through a restricted choke size of 60/64 inch. Lundin will now sidetrack the well to confirm the lateral continuity of the reservoir towards the west. The well will then be plugged and abandoned after it reaches a total depth of 6,627 feet (2,020 meters). Drilling of the second appraisal well will take place shortly with the Bredford Dolphin seimsub. Avaldsnes is located on Block 16/2 in 377 feet (115 meters) of water. Lundin Petroleum operates the discovery with a 40% interest; Statoil with 40%; and Maersk with the remaining interest.

Lundin Spins Bit at Avaldsnes Appraisal
Type: Status Update

May. 2011 - Lundin Petroleum has started appraisal drilling of well 16/3-4 on the Avaldsnes discovery located in PL 501 in the Norwegian sector of the North Sea. Lundin plans to delineate the discovery that was made in 2010. The target is to confirm the presence of late Jurassic sand about 3 miles (5 kilometers) southeast of the Avaldsnes discovery well 16/2-6. The planned total depth is approximately 6,562 feet (2,000 meters) and the well will be drilled using the Bredford Dolphin semisub. Drilling is expected to take about 45 days. The second appraisal well, 16/2-7, will spud following the completion of well 16/3-4 using the same rig. The water depth at the site is 377 feet (115 meters). Lundin Petroleum operates the prospect, holding a 40% interest; Statoil holds 40%; and Maersk Oil Norway AS holds 20%.

Lundin Hits Pay in Avaldsnes Prospect
Type: New Discovery

Sep. 2010 - Lundin Norway made an oil discovery in exploratory well 16/2-6 on the Avaldsnes prospect in Production License 501. The well's primary exploration target was to prove petroleum in Upper Jurassic reservoir rocks in the Hugin formation, while the secondary target was to prove petroleum in reservoir rocks in the Lower Paleocene in the Ty formation. Drilled to a vertical depth of 6,995 feet (2,132 meters), the well terminated in the Zechstein group in the Upper Permian section. Oil was proven in a 56-foot (17-meter) column in the Draupne and Hugin formation in the Upper to Middle Jurassic, while the Ty formation lacked reservoir formation. A formation test was performed, showing very good flow properties. The Avaldsnes discovery is estimated to contain recoverable resources of 100 to 400 million barrels of oil equivalent (MMboe) within PL501. Additional appraisal wells will be required to fully delineate the structure, and preliminary plans are to drill further wells in 2011. The water depth at the site is 377 feet (115 meters). Lundin Petroleum operates the prospect, holding a 40% interest; Statoil holds 40%; and Maersk Oil Norway AS holds 20%.

Lundin Spuds Avaldsnes Prospect in North Sea
Type: Status Update

Jul. 2010 - Lundin Petroleum has spudded exploration well 16/2-6 on the Avaldsnes prospect offshore Norway. The well is located about 16 miles (25 kilometers) east of the Luno discovery, on the opposite side of the Utsira structural high. The target is a Lower Cretaceous/Jurassic age sandstone sequence, analogous to the Luno reservoir, within a combined stratigraphic/four-way-dip closure. It is estimated that the gross unrisked prospective resource of the primary Avaldsnes target is about 130 million barrels of oil equivalent. Lundin is using the Transocean Winner semisub for drilling operations, which should last about 38 days, excluding testing. The water depth at the site is 377 feet (115 meters). Lundin Petroleum operates the prospect, holding a 40% interest; Statoil holds 40%; and Maersk Oil Norway AS holds 20%.
