Sunbird Discovery in Block 10A Offshore Kenya Unlikely to be Commercial

Pancontinental Oil and Gas NL, an Australian listed petroleum exploration company, revealed Monday that the Sunbird-1 well off the southern Kenyan coast has been completed and the well has intersected a hydrocarbon-bearing zone in the top of the Sunbird Miocene Pinnacle Reef. Analysis of the zone itself and recovered hydrocarbon samples are continuing.

Analysis of the wireline log data and the fluid samples recovered from the limestone reservoir is complex due to the large volume of drilling fluid, seawater and cement lost to highly porous and permeable zones in the Sunbird Reef, including into the hydrocarbon bearing zone.

Both gas and liquid samples have been recovered. In addition to the recovered gas, the nature of the liquid samples and whether or not these contain naturally occurring hydrocarbon liquids (oil or condensate) remains to be determined by further analysis.

The top of the Sunbird Miocene Pinnacle Reef was reached at 5,195 feet (1,583.7 meters) subsea. The water depth is 2,372 feet (723 meters).

The 143 foot (43.6 meter) gross hydrocarbon bearing zone is currently assessed to contain a net pay thickness of 91 foot (27.8 meter). In this case, net pay is defined as the cumulative thickness of zones having porosity of 10 percent or greater. Zones with porosity lower than 10 percent are not included in the net pay assessment.

At this stage, due to its estimated size, the Sunbird discovery itself is considered unlikely to be commercial.

Pancontinental has an 18.75 percent interest in the well and block L10A.
