Kenya exploration and appraisal update
22 January 2015 - Tullow Oil plc (Tullow) provides an update on
a series of exploration and appraisal activities in onshore Kenya
Blocks 10BB, 13T and 10BA.
Epir-1 exploration result
The Epir-1 exploration well is located in block 10BB in the
North Kerio Basin, a separate sub-basin from that tested by the
Kodos-1 well, 25 km to the southwest. Whilst not a discovery, the
well encountered oil and wet gas shows over a 100 metre interval of
non-reservoir quality rocks, demonstrating a working petroleum
system in this lacustrine sub-basin. Further exploration activities
will be considered in the North Kerio Basin following analysis and
integration of the valuable data collected from the well.
The Weatherford 804 rig drilled the Epir-1 well to a final depth
of 3,057 metres. The well will be plugged and abandoned, following
which the rig will move to the Ekales-2 location in the South
Lokichar Basin where it will conduct appraisal of the discovery
made by the Ekales-1 well. The well will target reservoirs in a
separate fault block to the east of the discovery well, further
away from the basin bounding fault.
Engomo-1 exploration well commenced drilling
The new SMP-106 rig has commenced drilling the Engomo-1 well,
the first test of the prospective North Turkana Basin in Kenya
Block 10BA. This onshore prospect is to the west of Lake Turkana
where numerous naturally occurring oil slicks and seeps have been
observed. A result is expected during early March 2015.
Ngamia and Amosing appraisal wells
The PR Marriott 46 rig recently completed drilling the Ngamia-5,
Ngamia-6 and Amosing-3 appraisal wells. Both Ngamia wells were
drilled from the Ngamia-1 discovery well pad. Ngamia-5 was drilled
to a final depth of 2,317 metres and was deviated approximately 500
metres northeast of Ngamia-1, encountering between 160 to 200
metres of net oil pay. Ngamia-6 was drilled to a final depth of
2,480 metres and was deviated approximately 800 metres north of
Ngamia-1, encountering up to 135 metres of net oil pay. Both wells
have been suspended and remain available for use in an Extended
Well Test programme that will commence in the second quarter
2015.
The Amosing-3 well in Block 10BB continued the successful
appraisal of the Amosing oil field. The well was drilled
approximately 1 km northwest of the Amosing-1 discovery well and
successfully encountered over 107 metres of net oil pay in good
quality reservoir sands. The well reached a final depth of 2,403
metres and has been suspended for use in future appraisal and
development activities. The PR Marriott 46 rig will now be moved to
continue the appraisal of the Ngamia field, drilling the Ngamia-7
well to test the field's eastern flank.
South Lokichar Basin 3D seismic
Acquisition of the large 951 sq km 3D seismic survey has
completed over the series of significant oil discoveries in the
western basin bounding fault play of the South Lokichar Basin. The
fast-track processed data is already being used in the south of the
basin whilst the remainder of the survey will be available for
seismic interpretation by the end of the first quarter 2015.
Initial evaluation of the 3D seismic data indicates significantly
improved structural and stratigraphic definition and additional
prospectivity not evident on the previous 2D seismic data. In
addition, the partnership has acquired over 1,100 metres of core
samples from the South Lokichar Basin wells and an extensive
programme of detailed core analysis is ongoing that will provide
results from the first quarter 2015 onwards, to measure oil
saturation and assess recovery factors of the reservoir sands.
Tullow Operates Blocks 10BB, 13T and 10BA with 50% equity and is
partnered by Africa Oil Corporation, also with 50%.
Commenting today, Angus McCoss, Exploration Director, said:
"The Epir-1 wildcat well proved the existence of a working oil
system in the North Kerio Basin, encouraging us to consider further
exploration activities. The Ekales-2 exploratory appraisal well is
a bold step-out away from the South Lokichar Basin bounding fault
with follow up potential. Continued success in the appraisal of the
Ngamia and Amosing oil fields is highly encouraging as we continue
with development studies for the South Lokichar Basin."
