Tullow Oil plc (“Tullow”) announces that the Wisting Central exploration well (7324/8-1), offshore Norway, has made the first ever oil discovery in the Hoop-Maud Basin in the Barents Sea.
Results of drilling, wireline logs and samples of reservoir fluids show that the well has encountered 50-60 metres of net light oil pay in good quality relatively shallow Middle to Lower Jurassic reservoir rocks. Following evaluation of the results, further delineation of the discovery and exploration drilling in the licence will be required.
The well was drilled by the Leiv Eiriksson semi submersible rig and is located approximately 170 kilometres northeast of the Skrugard/Johan Castberg discovery well and 310 kilometres north of Hammerfest. The well was drilled to a total depth of approximately 905 metres in a water depth of 373 metres. Following significant data acquisition, the rig will move to drill the deeper and independent Kobbe prospect in the same production licence and will not appraise this shallower discovery.
The Wisting Central discovery is located in licence PL537 in which Tullow has a 20% interest. OMV (Norge) are the operator with a 25% interest while Idemitsu (20%), Statoil (15%) and Petoro (20%) are also partners.
