On 9 February 2019 Equinor used the Visund A drilling facility to spud exploration well 34/8-18 S targeting the Telesto prospect in PL 120. The well is a deviated exploratory extension of development well 34/8-A36 H, with its top hole location in the centre of Visund. TD was reached at 6,068 m (3,298 m TVDSS) in the Upper Triassic Lunde Formation and it has made a new, small oil discovery. A 115 m oil column was proven in the Upper Triassic Statfjord Group, with two sandstone reservoirs of 17m (upper) and 20 m (lower), and an OWC at 3,170 m subsea. There was also 15 m of water-wet sandstone in the Lunde Formation. Estimated recoverable reserves are 12-28 MMboe and development using the Visund facilities is likely. The well was abandoned on 22 February 2019.   This is the second exploration well in PL 120 within the last 12 months. In June 2018, the company drilled 34/8-19 S from the Visund North template, targeting the Tarqeq / Aegir prospects which had Lower Jurassic Cook Formation and Upper Triassic Statfjord Formation objectives. A 90 m section of Cook Formation was present with 22 m of sandstone but no hydrocarbons. The Statfjord Formation was not reached due to technical issues.     Interest in PL 120 is divided between Equinor Energy AS (59.06% + operator), Petoro AS (16.94%), ConocoPhillips Skandinavia AS (13%) and Repsol Norge AS (11%).
034/08-18S (Telesto) (Equinor op. 59,07%, Petoro 16,93%, COP 13%, Repsol 11%) Visund A platform in PL 120, minor oil disc, 115m oil column in the U&L parts of the Statfjord group, 17-20m net, OWC in the L. Statfjord group at ab. 3170m, the resources are estimated at 12-28 MMbl of recoverable oil.
