OMAN ASSET PRODUCTION AVERAGED 10,944 BOPD IN MAY


Test production from the Early Production System (EPS) on Blocks 3 and 4
onshore the Sultanate of Oman continues and amounted in May 2012 to 339,270
barrels of oil, corresponding to 10,944 barrels of oil per day (BOPD). Tethys’
share of the production, before government take, amounts to 30 per cent of the
total, or 101,781 barrels.


In the end of May, the preparation work was initiated for the launch of the
export pipeline, connecting the oil fields with the national Omani
transportation system. This pipeline is expected to be operational before the
end of the second quarter. The work affected the production somewhat in May,
and will continue to affect the June production.

Long term production tests have been carried out on wells from both the Saiwan
East oil field on Block 4 and the Farha South oil field on Block 3. Production
rates continue to vary depending on test programme design and available
capacity.

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.
