Soco Reaches Total Depth on Ca Ngu Vang Appraisal Well

The appraisal well on the Ca Ngu Vang structure that spudded on January 29, 2005 reached target depth on 16 April 2005. At a measured depth of 6,123 meters, this gives the CNV-3X well the distinction of being the longest MD well ever drilled in Vietnam. The well reached a total vertical depth of 4,426 meters penetrating 2,017 meters of Granitic Basement at an average angle of 82 degrees from vertical intersecting various fault and fracture domains within the reservoir. It is anticipated that the well will take some two to three weeks to test.
