Independent oil and gas exploration and production group Tullow Oil said its exploration well on the Mantra prospect offshore Norway has encountered reservoir quality sands but all intervals are water wet. As a result, drilling at the well in the North Sea has been terminated and will now be logged before being plugged and abandoned."The 31/3-4 wildcat was the first exploration well in the Tullow operated 551 production licence and was targeting the Upper Jurassic Sognefjord Formation reservoir as the main target, with additional prospectivity in Paleocene Lista sands and Middle Jurassic Brent."The semi-submersible drilling rig Transocean Barents drilled 31/3-4 to a vertical depth of approximately 2,082 metres subsea before it was terminated in the Middle Jurassic Brent," explained Tullow. The group said the well, located approximately 10km north of the Troll C platform in the North Sea, will now be logged before being plugged and abandoned.
