High Pressure High/High Temperature (HPHT) Discovery Offshore Norway

Location of the Hades/Iris well. Map credit: Drillinginfo. The Hades/Iris new field wildcat 6506/11-10 was plugged and abandoned in April 2018 as a gas/condensate discovery. The well encountered a 35m gas/condensate column, with 15m of moderate to good sandstone reservoir in the primary target (Hades) Early Cretaceous Lange Formation, at 3,932m with estimated recoverable resources of 20–115 MMboe. 

The secondary target, Iris, in the middle Jurassic Garn Formation, was intercepted at 4,223m and had a total gas condensate column of 95m, with 85m of moderate to very good sandstone reservoir and a gas/water contact at 4,295m SSTVD. Estimated ecoverable resources are 20–130 MMboe. The well TD’d at 4,536m MD.

This high pressure/high temperature (HPHT) well, spudded in November 2017 in PL644 B in Norwegian Sea block 6506/11, is 8 km north of the Morvin oil and gas field, which has Middle Jurassic Ile and Garn Formation reservoirs. 

Current equity partners are operator OMV (Norge), holding 30%, with Statoil Petroleum (30%), Bayerngas and Centrica JV, Spirit Energy Ltd (20%) and Faroe Petroleum (20%).
