Matra Petroleum has provided an update on its appraisal well-13 on the Sokolovskoye field, in the Orenburg region, Russia.

As announced on December 22, 2009, due to the technical difficulties encountered at the depth of 738 meters, the Company suspended drilling in order to regain control of the well and permit it to drill down to the projected total depth of 3850 meters.

While drilling has not yet re-commenced, considerable progress has been made in controlling the Nitrogen influx and curing mud losses. The wellbore appears to be in good condition and the drill string has been pulled back into the safety of the casing at 650m.

Prior to restarting drilling operations, Matra has also served notice on Petromanagement Drilling and has identified a replacement contractor with a view to improve performance and efficiency.
