Operational update Oman

• Exploration well 5 (B4EW5) encounters oil and flows in excess of 200 BOPD
• Appraisal of B4EW4 discovery continues with Lower Buah appraisal well
The exploration well 5 (B4EW5) on Block 4 onshore the Sultanate of Oman has
been drilled to a total depth of around 3,000 metres. The well recorded oil
shows in five separate formations. The well has been completed in the Lower
Buah and produced by natural flow in excess of 200 BOPD. Operations with a view
to increase the production rate will be carried out and plans are to place the
well on a long term production test.
The well 5 structure (B4EW5) is a look alike structure to the producing well 4
structure (B4EW4), and was identified from recently completed 3D seismic.
“We are encouraged by discovering oil also in the new structure. Like in the
previous structure, oil shows were present in several formations, while the
production from the Lower Buah is still considerably lower than that obtained
from well 4 (B4EW4). As work continues we will learn more about the long term
potential of the new discovery,” comments Tethys managing director Magnus
Appraisal drilling continues on the well 4 (B4EW4) discovery. A new appraisal
well is in progress southeast from the discovery well. The new well is being
drilled to further appraise the extension of the Lower Buah reservoir section.
The well 4 structure (B4EW4) continues to yield good flows from the Lower Buah
under the long term production test from the previously completed wells.
