Oman: Saiwan East well finds Neoproterozoic oil

HOUSTON, Apr. 6
– A group led by CC Energy Development SAL found heavy oil in several formations at the Saiwan East-7 well on Block 4 in eastern Oman.

SE-7 was drilled to a total depth of 1,890 m and found several intervals of heavy oil but established no flow. CCED temporarily suspended the well for possible testing and further study, said interest owner Tethys Oil AB, Stockholm.

The main target was to test the presence of oil in the Neoproterozoic Khufai section in the southern part of the Saiwan East structure. The well identified a more than 90-m thick column of intermittent heavy oil saturation in the upper parts of the Khufai. A limited test program was run using a wireline MDT tool, but no flow was established.

As expected, heavy oil was also encountered in the shallower Neoprpterozoic Buah and Cambrian Miqrat and Amin formations.

The rig moved to drill the Farha South-7 well on Block 3, an appraisal well designed to test for the presence of oil in the Lower Al Bashir section near the Farha South-3 well in Farha South field. The drill site is located 425 m southwest of FS-3, drilled in early 2009.

Interests in blocks 3 and 4 are CCED 50%, Tethys Oil 30%, and Mitsui E&P Middle East BV 20%.
