LONDON, Addax Petroleum Corporation announced
flow test results for the TT-06 well, the third
appraisal well recently drilled on the Taq Taq field
in Kurdistan region (Iraq) by Taq Taq Operating
Company, the joint venture company formed by Genel
Enerji A.S. ("Genel") and Addax Petroleum to carry
out the petroleum operations in the Taq Taq license
area.
Three reservoir intervals were tested separately and
flowed at an aggregate rate of 18,900 bbl/d of light
oil, measured gravity of 48 degrees API with low gas
oil ratio. The intervals tested were a 105 meter
perforated interval in the Shiranish formation which
flowed at a rate of 15,380 bbl/d, a 51 meter
interval in the Kometan formation which flowed at a
rate of 2,020 bbl/d and a 10 meter interval in the
Qamchuga formation which flowed at a rate of 1,500
bbl/d. Oil flow rates from the Shiranish, Kometan
and Qamchuga intervals were restricted by 128/64",
40/64" and 32/64" choke sizes respectively.
Evaluation of these flow test results is ongoing. |

The TT-06 well is a step-out located approximately
3.6 kilometres north-northwest of the TT-05 well
along the length-wise axis of the Taq Taq field. It
is the first attempt to define the areal extent of
the Taq Taq structure. The TT-06 well was spudded in
early January and completed drilling in April at a
total depth of 2,085 metres. Testing of TT-06
commenced in mid May, 2007.
Interpretation of data acquired from TT-06,
including wireline and core data, confirms the
presence of a significant and extensive fracture
system as observed in the TT-04 and TT-05 wells in
the Shiranish formation. Although restricted to a
40/64" choke size, the Kometan formation tested in
the TT-06 well appears to have a lower fracture
density and smaller fracture apertures, as compared
to the TT-04 and TT-05 wells.
In addition, the Kometan formation tested in the
TT-06 well may have experienced formation damage
which may have further restricted its test flow
rate. The flow rate in the Qamchuga formation was
limited by a 32/64" choke size to restrict the
coning of water due to the proximity of the tested
interval to the oil water contact. None of the
tested intervals in the TT-06 well were stimulated.
The TT-06 well is the third of a six well drilling
program by Genel and Addax Petroleum. The drilling
of the fourth appraisal and development well, TT-07,
is now in progress. The TT-07 well was spudded in
late April and is located approximately 2.2
kilometres southeast of the TT-05 well along the
length-wise axis of the Taq Taq field.
The Taq Taq field is located in the Kurdistan Region
of Iraq some 60 kilometres northeast of Kirkuk, 55
kilometres southwest of Erbil and 120 kilometres
northwest of Sulaimaniyah.
