Described as a high-impact appraisal/exploration well, Heritage Oil has spudded its Kingfisher 2 well in Block 3A. This permit covers 2,024 sq km and extends over the south-eastern part of Lake Albert; it is due to expire in September 2010. This well will be drilled from land using the Nabors 221 rig and will be deviated away from the basin margin fault to reach the basin floor at a planned depth of around 4,100m. It will appraise the reservoir zones discovered by the 2006 Kingfisher 1 well. These productive zones were secondary objectives, since the primary, Lower Miocene deeper target was not reached for reasons related to rig performance. The Kingfisher 1 discovery reached a total depth of 2,125m in the basement and encountered oil shows in four zones over a total net pay of 37m in a stacked sand and shale sequence. The Kingfisher 1A sidetrack indicated the presence of three additional potential oil-bearing zones below 2,260m. Three tests were performed in the Upper Miocene section achieving a cumulative maximum flow rate of 13,893 b/d of light (30-32° API) sweet crude with a low gas-oil ratio and some associated wax. Gross contingent resources for Kingfisher have been assessed at 118 MMb for the secondary zones and 698 MMb for the primary objective. Heritage has plans for further drilling on the Pelican prospect and other structures in Block 3A utilizing a rig capable of drilling in Lake Albert. A possible two wells may be drilled on the Kingfisher structure while two or three wells may be drilled in Block 1 targeting relatively shallow structures.
