Description
 
The Carnaby prospect is situated on Block 28/9 within License P1430 in the UK sector of the North Sea. Premier Oil is the operator of the prospect with a 50 percent stake; while Wintershall holds 20 percent; Cairn Energy holds 15 percent and Nautical holds the remaining 15 percent.

Premier reached a total depth of 4,695 feet (1,431 meters) in the Carnaby exploration well and encountered oil. Initial analysis indicates that the well encountered 51 feet (15 meters) of net oil in the main Tay sandstone within an estimated 86 feet (26 meters) oil column. A core was taken and confirmed oil in excellent quality sandstones. Pressure data and sampling indicates that the API of the oil is 24 degrees and is of similar quality to that established at the nearby Catcher discoveries. The oil water contact was at the shallower end of expectation; driven by the more complex geology associated with this type of footwall prospect.

The well also encountered 51 feet (15 meters) of Cromarty sands but these were shown to be water wet on the logs. The high quality data acquisition from the well will now be used to determine what contribution the Carnaby discovery will make to the overall Catcher development. The well will be plugged and abandoned.

The high quality data acquisition from the well will now be used to determine what contribution the Carnaby discovery will make to the overall Catcher development. The well will be plugged and abandoned ahead of the rig moving to drill the high risk Coaster prospect on Block 28/10a, immediately east of the Catcher acreage.

Exploratory Drilling - May 10, 2012 to Jun 10, 2012
Premier Oil is using the Sedco 711 mid-water floater to drill its Carnaby prospect on Block 28/09. Drilling operations are being managed by ADTI.
Bright Spot - Apr 01, 2007 to May 09, 2012
UK License P1430 (covering block 28/9) was originally acquired in April 2007 by a partnership of Oilexco, EnCore and Nautical Petroleum under a UK Traditional licensing agreement. Premier Oil acquired EnCore in 2011 and assumed operatorship. This prospect is part of the Greater Catcher Area.
