Block 14/30a Tudor Rose (Licence P1463)
(Nautical 20%)

Located in the Outer Moray Firth adjacent to Ivanhoe, Rob Roy and Goldeneye fields this Traditional Licence, contains 1 undeveloped discovery, 14/30a-2, named Tudor Rose. The well encountered a 24 metre oil column beneath a 3 metre gas cap at around 1000 metres subsea within Tertiary, Dornoch formation sands. Further prospects have been mapped on 3D seismic within the Lower Cretaceous Kopervik sand and the Jurassic Sgiath sand.

Interpretation of 208 square kilometres of 3D seismic was completed in 2010, yielding encouraging results. The western pinch out of the Dornoch sands was confirmed and the area of the stratigraphic trap in two sand bodies (one undrilled) extended to the south.

Gas anomalies (1 coincident with the gas in 14/30a-2) were mapped within the stratigraphic closure.

Following further engineering studies and the interpretation of amplitude versus offset (AVO) seismic volume, the Joint Venture drilled an appraisal well, targeting the Dornoch reservoir (Beauly Formation), in Q4, 2011.

The purpose of the well was to obtain an uncontaminated hydrocarbon sample, allowing the co-venturers to better understand the oil quality, including the oil gravity and viscosity, with a view of being able to assess the potential commerciality of the field.
 
As announced on 20 December 2011 the 14/30a-5 well encountered a 22 feet net oil column within the target Beauly Formation and Oil Water Contact at 3,236 feet Total Vertical Depth Subsea.  Wireline sampling and pressure testing of the oil bearing zone has been undertaken and preliminary wellsite analysis suggests a very heavy crude, with a viscosity of 600-800 centipoise, which is unlikely to be commercially exploitable.
