West Mailisu 2 Swabbing Equipment Delay

Monday, August 29th, 2011

Caspian Oil & Gas Limited reports that after perforating Bed III with a shot over the interval 1785-1795.5m progress on its West Mailisu #2 well has been slowed by the unavailability of equipment.

The West Mailisu #2 well is on Caspian’s 100%-owned West Mailisu licence in the Kyrgyz Republic, Central Asia.

The perforating was completed with a water cushion of approximately 1450m as a safety measure. A small
amount of movement in the fluid height in the well bore was observed on perforation and some oil was
recovered on the drill pipe which had been run into the hole as a kill string.

Originally, it was planned to blow the fluid from the hole using compressed air but the service provider’s
compressor experienced mechanical problems. Pending resolution of the compressor issues it will be
necessary to remove the fluid from the hole by swabbing. While delays occurred in obtaining suitable
swabbing equipment, it is hoped this activity can be completed in the next few days
