Tullow Oil will abandon and plug the exploration well 31/2-21S in the Gotama prospect, offshore Norway, after its drilling programme failed to identify reservoir quality sandstones in the Upper Jurassic main target.
The well, which was drilled to a depth of 3,217m, did not encounter reservoir quality sandstones in its Upper Jurassic main target, whilst reservoirs in the secondary targets proved water wet.
The 31/2-21S well was the first exploration well in the 550 licence, which is operated by Tullow Oil with an 80% stake.
Tullow Oil’s partners in the prospect are Det Norske and VNG Norge, holding 10% equity each.
The well, which was drilled using the Borgland Dolphin semi-submersible rig, is located approximately 12km north-west of the Troll C Platform and 120km north-west of Bergen.
Tullow has hit several dry wells over the last 18 months, mainly in Mauritania, French Guiana, Kenya and Ethopia.

In April 2014, Tullow plugged and abandoned the Tapendar-1 exploration well in the C-10 licence, offshore Mauritania, after its failure to encounter hydrocarbons.
Tullow operates the C-10 licence with 59.10% equity and its partners in the prospect are Premier Oil, Kufpec, Petronas and SMHPM.
Tullow focuses on finding oil in Africa and the Atlantic Margins, combined with selective development and high-margin production to fund its exploration-led strategy.
The company claims that it made its largest discovery to date, the Jubilee field offshore Ghana, in 2007.
