The drilling program onshore the Sultanate of Oman continues. One exploration/
appraisal well and two production wells have successfully been drilled,
completed and hooked up to the Early Production System ("EPS") on the Farha
South Oil Field on Block 3. In addition, two water injection wells have been
drilled, and currently two new production wells are drilling.


The Farha South-16 ("FS-16") was drilled as a vertical exploration/appraisal
well through both the Barik and Lower Al Bashair formations. The drill site is
located 5.5 kilometres northeast of FS-5 in a previously undrilled fault block.
The well was drilled to a total depth of 1,747 metres. The well encountered the
Barik formation at 1,095 metres depth. A total of 30 metres of oil-bearing
sandstone was drilled. Oil shows were also found in the Lower Al Bashair
formation ("LAB"). The Upper Barik section has been perforated and put into
test production with an electrical submersible pump.

Two new production wells have also been drilled and completed in previously
drilled and known oil bearing fault blocks on Farha South, the FS-14 and FS-8
wells. The wells encountered oil, both in the Barik and the LAB sections. In
FS-14 the Upper Barik section has been successfully completed, and FS-8
completed in the Lower Al Bashair. Both are connected to the EPS to be part of
the ongoing long term production test of the area. The production rates from
the EPS will continue to vary, depending on both the test programme design as
well as on transport and facility capacity.

Two water injection wells have also been drilled on Farha South. The two rigs
in operation are currently drilling the production wells FS-19 and FS-20.

Tethys has a 30 per cent interest in Blocks 3 and 4. Partners are Mitsui E&P
Middle East B.V. with 20 per cent and the operator CC Energy Development S.A.L.
(Oman branch) holding the remaining 50 per cent.
