On 11 August 2020 Spyker Energy exited the 12/06 and 04/16 licence which covers blocks 5504/20 W, 5504/24 SW and 5504/20d and hosts the Lille John and Broder Tuck discoveries. The 8% interest in each licence that was held by Spyker Energy has been split between the remaining participants. Operator of the licences, Dana Petroleum, plans to drill an appraisal well on each licence in 2021. The licences are located south of the Tyra field.   The Broder Tuck gas condensate discovery was drilled by wildcat Lola-1 in 1975, it encountered gas in a Middle Jurassic sandstone. Broder Tuck 1 was spudded in 2011 but was junked after drilling the top-hole section and re-spud as Broder Tuck 2 in May 2011. The well proved gas bearing in a high-quality Middle Jurassic reservoir at approximately 3,400 m subsea with 17 m of net pay. Broder Tuck-2A was drilled to further appraise the discovery. The sidetrack confirmed the find at a location approximately 680 m from the bottom hole of the original wellbore and confirmed a total gross hydrocarbon column of 360 m for the field.   Lille John discovery was made in 2011 by the Lille John 1 exploratory well that encountered a Miocene reservoir between 900 m to 1,200 m. Appraisal well Lille John 2 was drilled between 2014 and 2015 and tested at a constrained rate of 500 bbl/d plus 0.25 MMcf/d to avoid sand production but it was later raised to 1,400 bbl/d with no sand. Sidetrack Lille John 2A was drilled in early-2015 and was oil bearing. The wells have proven an approximately 300 m thick oil column with better reservoir quality encountered in the appraisal well compared to the discovery well.   Interest in licences 12/06 and 04/16 is held by Dana Petroleum Denmark BV (43.48% + operator), Petrogas E&P UK Ltd (20.65%), Danoil Exploration A/S (10.43%), Petrogas Denmark ApS (5.44%) and Danish North Sea Fund (20%).
