The development and exploration programme on Blocks 3 and 4 onshore the Sultanate of Oman accelerates after a second drilling rig has been contracted. The first well being drilled by this rig is the Farha South-6 well (FS-6) on Block 3.

The new rig, a 750 horsepower Deutag T-55, is operated by UK drilling contractor KCA Deutag Drilling Company. The new rig will be used alongside the Abraj 204 rig already in use on the Blocks, and currently drilling the SE-7 exploration well on Block 4.

"We are very pleased that the work programme of Blocks 3 and 4 of Oman is been accelerated, underpinning both the extent of Blocks 3 & 4 areas which remain un-explored to-date as well as remaining geological uncertainties before a fully-fledged development plan is put in place. Two rigs will allow a speedier drilling schedule for 2011," says Magnus Nordin, Managing Director of Tethys Oil AB.

FS-6 is drilled as a vertical well, designed to target the lower Barik formation. The drill site is located 140 metres southeast of well FS-4 and 750 metres south-southwest of well FS-3.

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 E nergy Development S.A.L. (Oman branch) holding the remaining 50 per cent.
