Tullow’s Gotama Well Ends Up Dry


Tullow Oil plc has announced that exploration well 31/2-21S which was targeting the Gotama prospect, offshore Norway, did not encounter reservoir quality sandstones in the Upper Jurassic main target.

The well encountered reservoir quality sandstones in the secondary targets, but these intervals are water wet.

The 31/2-21S wildcat was the first exploration well in the 550 licence and was targeting sandstone reservoirs in the Upper Jurassic Draupne Formation as the main target and additional sandstone targets in the Middle Jurassic Sognefjord Formation and Brent Group.

The well was drilled by the Borgland Dolphin semi submersible rig and is located approximately 12 kilometres northwest of the Troll C Platform and 120 kilometres northwest of Bergen. The well was drilled into the Lower Jurassic Cook Formation to a total depth of 3217 metres in water depths of 348 metres and will now be plugged and abandoned.

Tullow operates the 550 licence with 80% equity and is partnered by Det Norske (10%) and VNG Norge AS (10%).
