October 18, 2007 — Tbilisi, Georgia — CanArgo Energy Corporation (“CanArgo” or the “Company”) (OSE: CNR, AMEX: CNR) today issued an update on testing operations on the Kumisi #1 well and the planned acid fracturing stimulation of the Manavi 12 well in Georgia.
Testing operations have now been completed at the Kumisi #1 well. Following testing of the Cretaceous interval, further tests were carried out of potential reservoir units in the overlying Middle and Lower Eocene sequences. Three separate tests were conducted with a total of 79 feet (24 metres) of sandstones being perforated and flow tested. These tests produced water with gas flow to surface in flareable quantities, but non commercial volumes. Each interval was flow tested for a number of days over which there was no increase in the amount of gas produced and the testing was subsequently terminated.
The Kumisi #1 well is currently being plugged and abandoned. The well results, particularly for the Cretaceous interval, will be reviewed over the months ahead in order to fully understand the remaining potential of the Kumisi area, it being possible that potential for a large gas prospect still exists within this very large structure given better reservoir quality.
At the M12 well located on the Manavi oil discovery, operations continue in order to prepare the well for the planned acid fracture stimulation treatment and to continue production testing the well. Schlumberger have been contracted to provide pumping equipment, chemicals and services to the Company. An initial mobilisation date was planned for late September, but Schlumberger has now informed the Company that, due to unforeseen circumstances, they will not be ready to commence mobilisation of the equipment before the end of October or early November. It is therefore anticipated that the fracture stimulation will now be done in November after which the well will be flow tested.
