Equinor spudded 30/6-31 S using the "West Hercules" S/S on 4 April 2020. The rig was on site on 11 March 2020 but a few days later it had left and was back at shore, delayed due to the coronavirus disease 2019 (COVID-19). 30/6-31 S targeted the Middle Jurassic Helleneset prospect on the eastern flank of Oseberg in PL 053 and it was drilled to TD at 2,852 m (2,832 m TVD) in the Middle Jurassic Ness Formation. The Intra Heather Formation objective contained poorly developed sands and the well is dry. It was abandoned on 25 April 2020.   Equinor was successful earlier in the year (July 2019) in drilling a well on the western flank of Oseberg. An exploration extension of development well 30/6-H9 (T4) found a 112 m oil column in the Lower Jurassic Statfjord Formation in the southern part of the Alpha structure, a segment of Oseberg that was previously undrilled (and known as Alpha Main Statfjord). Estimated recoverable reserves are 22 MMbo. Equinor brought the new volumes online shortly after discovery and was considering the use of water injection to boost production further. The drilling was part of the Oseberg Vestflanken 2 project which came onstream in October 2018 using a new platform â Oseberg H.  Interest in PL 053 is divided between Equinor Energy AS (49.3% + operator), Petoro AS (33.6%), Total E&P Norge AS (14.7%) and ConocoPhillips Skandinavia AS (2.4%).
