Block 4 exploration well 4 (B4EW4) encounters oil – testing in progress

The exploration well B4EW4 onshore Oman has drilled to a final total depth of
3,030 metres. Wireline logging operations has been completed and a testing
program has commenced. The well has encountered oil in four separate formations
(Lower Al Bashir, Buah, Khufai and Masirah Bay). The result of the testing
program is expected within three weeks.
B4EW4 was spudded in November 2012 on Block 4. This well was drilled on a dense
grid of high quality 2D seismic data and is located approximately 20 km west of
the Saiwan East oil field. Strong oil shows were recorded during drilling in
the Lower Al Bashair, Buah, Khufai and Masirah Bay formations. PVT oil samples
were acquired during wireline logging operations in the Lower Al Bashir, Buah
and Masirah Bay formations. The testing program is designed to evaluate the
Khufai and Buah reservoirs.
