Tullow Oil PLC (TLW.LN) said Wednesday the Mahogany Deep-2
appraisal well offshore Ghana confirmed the down-dip extent of the
main Jubilee reservoirs in the West Cape Three Points Block and
intersected two new light oil accumulations.
MAIN FACTS:
-Good quality reservoirs were encountered in the Mahogany Deep
section but were water bearing at this location.
-Mahogany Deep--2, drilled 3 km from Mahogany--3, is the
furthest down-dip Jubilee well in the West Cape Three Points
license.
-Results of drilling, wireline logging and samples of reservoir
fluid indicate that the well has encountered good quality
hydrocarbon-bearing reservoir sandstones in three zones.
-An interval of 12 meters net pay has proved an extension of the
main Jubilee reservoirs. In addition, a new shallower accumulation,
with 2 meters net pay, was encountered and supports exploration
prospectivity in undrilled areas to the south and east.
-In total, the well intersected 53 meters of net reservoir
sandstones, 20 meters of which were in the Mahogany Deep
section.
-These were found to be water bearing at this location but are
not connected to the Mahogany Deep accumulation at Mahogany--3.
-Further extensions to the Mahogany Deep accumulation may exist
to the south and east of Mahogany--3.
-A new reservoir was also encountered in a deeper stratigraphic
level beneath the Mahogany Deep section and an oil sample was
successfully recovered from a 1 meter zone which has not been
encountered in any other wells in the West Cape Three Points
license to date.
-Further potential extensions of the Jubilee field and
associated prospectivity will be drilled early in 2010.
-The Aban Abraham dynamically positioned drill-ship drilled
Mahogany Deep--2 to the current depth of 4,326 meters in water
depths of 1,354 meters.
-Tullow has a 22.896% interest in the West Cape Three Points
license and its partners are Kosmos Energy (Operator) and a
subsidiary of Anadarko Petroleum Corporation, (30.875% each), the
E.O. Group (3.5%), Sabre Oil & Gas (1.854%) and the Ghana
National Petroleum Corporation (GNPC) (10% carried interest).
-Results from the current exploratory appraisal campaign are
being integrated to define the resource base and the future phases
of development beyond first oil in 4Q 2010.
-Currently drilling the potentially high-impact Tweneboa--2
appraisal well and expect to report on its result in February.
