STOCKHOLM, Sweden – The semisubmersible COSLInnovator has completed the latest Luno II appraisal well for operator Lundin Norway on the Utsira High in the Norwegian North Sea.
Well 16/4-11 in license PL359 was drilled 2.5 km (1.5 mi) south of theLuno II discovery well. Lundin’s main aim was to prove additional resources to progress the structure to development.
The well intersected a 22-m (72-ft) gross oil column in Triassic sandstone with better reservoir quality than expected, and encountered the oil-water contact at 1,947 m (6,388 ft) below the sea surface. Data acquisition and sampling followed, including conventional coring and fluid sampling.
Based on these results, Lundin has lifted its resource range estimate to 40-100 MMboe, and will now pursue technical studies with a view to submitting a plan for development and operation around the end of 2018.
Luno II will be a subsea tieback to the nearby Edvard Grieg platform. Other partners in the license are OMV, Statoil, and Wintershall.
On completion of the current program, theCOSLInnovator will drill appraisal well 16/1-28S on Lundin’s nearby Rolvsnes oil discovery in PL338C. In this case, the priority is to deliver commercial flow rates from a horizontal well that will be drilled in fractured and weathered basement reservoirs, similar to those currently producing in the northern area of the Edvard Grieg field.
Rolvsnes too is a possible tieback to the Grieg platform and drilling success here should de-risk the wider area prospectivity, estimated to contain gross resources of more than 200 MMboe. The drilling/testing campaign should last 115 days.
