• Intermediate logging of the Who Dat East exploration/appraisal well confirms high quality,
hydrocarbon-bearing sands in upper target sections, with a number of deeper targets still to
be drilled
• Preliminary interpretation of well data indicates an aggregateNet Pay thickness of 44 metres

• Following installation of 9-?” casing, the well will be drilled to the final Total Depth of 7900

Karoon Energy reports that the Who Dat East exploration/appraisal well, MC 509-1 (LLOG), has reached
a depth of 6,614 metres Measured Depth (MD) in the 12-¼” hole section. Intermediate wireline logging
was completed prior to setting 9-?” casing, and the well will drill ahead in 8-½”hole to a planned final
TD of 7,900 metres. The borehole angle through the 12-¼" hole section is approximately 45 degrees.
‘Logging While Drilling’ (LWD) and wireline logging data have indicated that a number of hydrocarbonbearing sandstones have been encountered within the targeted Middle Miocene turbidite sequences.
Interpretation of this data indicates a hydrocarbon bearing aggregate total Net Pay thickness of 44
metres MD within the targeted intervals, with 31 metres MD within two discrete reservoir units. Net
Pay porosities average 25% and correspondingly good permeabilities of between 300mD to >1,000mD
are indicated. A gas condensate hydrocarbon fluid type has been interpreted, as prognosed for this
well.
Wireline logging data, reservoir fluid samples and other geoscience data will be subject to laboratory
analyses and further studies to determine the resource potential of the hydrocarbon zones
encountered to date.
The forward plan is to complete running 9-?” casing before drilling to the planned Total Depth of
approximately 7,900 metres MD, to test the remaining targets.
Chief Executive Officer and Managing Director, Dr Julian Fowles, commented:
“Preliminary interpretation of the well data from the Who Dat East exploration/appraisal well is positive.
The early results indicate potential for a continuous hydrocarbon phase in a number of high quality sands
correlated to the nearby MC-509 Exxon #1 exploration well. Once the remaining targets have been drilled
and final TD logging completed, we shall be in a better position to evaluate any potential impact on
hydrocarbon volumetrics at Who Dat East, with a view to determining the commerciality of a potential
development. Furthermore, this early success at Who Dat East supports our belief that there is
exploration upside potential that can be unlocked surrounding Who Dat. Once drilling is complete the
well will be suspended as a potential future producer, pending the results of further analysis."
