On 3 February 2018 Fogelberg appraisal well 6506/9-4 S was spudded by Spirit Energy. The company used the âIsland Innovatorâ S/S to drill the well in PL 433. 6506/9-4 S is located in a down-dip position, approximately 1 km to the west of the discovery well, and was drilled to reduce volume uncertainty and confirm reservoir quality before the licence group commits to a FEED project. The well was drilled to TD at 4,738 m (4,580 m TVDSS) in the Middle / Lower Jurassic Tofte Formation and encountered a 63 m gross hydrocarbon column in the Middle Jurassic Garn Formation. The Middle Jurassic Ile Formation reservoir (70 m of sandstone) had very poor reservoir quality and high water saturation. On 28 April 2018 sidetrack 6506/9-4 A was kicked-off from the 14â casing (its location is where the development wells would be placed). Two cores were cut (around 4,288 m and 4,316 m) and the well reached TD at 4,497 m in the Tofte Formation. A 58 m gross hydrocarbon column was confirmed in the Garn Formation and an 87 m gross hydrocarbon column was present in the Ile Formation. The well was tested and flowed at a maximum constrained rate of 21 MMcfg/d plus 547 bc/d through a 36/64â choke. Preliminary estimated recoverable reserves are 40-90 MMboe â a formal volumetric update will be provided after further interpretation. With this well Fogelberg has been declared commercial and, if development proceeds, it will be as a subsea tie-back to Asgard B (located at the Smorbukk field) with a PDO being submitted in 2019 and a potential onstream date of 2022. On 3 July 2018 the well was being abandoned.    The licence term for PL 433 was extended in February 2017 with a deadline to submit a PDO by July 2019. The PDO was originally expected to be submitted in February 2017. Centrica (now Spirit) received MPE approval for the Environmental Impact Assessment (EIA) for Fogelberg in early 2014. The proposed plan (given at that time) included the installation of a four-slot subsea template (with three producers to be drilled initially) tied-back to either Asgard B or Heidrun. Costs were estimated at either NOK 7 billion (USD 1.18 billion) or NOK 11 billion (USD 1.86 billion) depending on which host facility was chosen.    The Fogelberg discovery well (6506/9-2 S) was Centricaâs first as an operator on the NCS and was drilled in 2010. Gas and condensate was confirmed in the Garn and Ile formations with no OWC indentified. Reserves at that time were estimated at 23-94 MMboe. The field is HPHT. It lies between Victoria and Smorbukk on the Halten Terrace.    Pending completion of a deal in PL 433 interest will be divided between Spirit Energy Norge AS (51.7% + operator), PGNiG Upstream Norway AS (20%), Faroe Petroleum Norge AS (15%) and Dyas Norge AS (13.3%).
