Section 7—Regulation FD
Item 7.01. Regulation FD Disclosure.
December 11, 2007 — Guernsey, Channel Islands — CanArgo Energy Corporation (“CanArgo” or the “Company”) (OSE: CNR, AMEX: CNR) today announced that the preparatory works being carried out at the Manavi 12 well in Georgia for the planned acid fracturing stimulation program have now been successfully completed.
The operator, CanArgo Georgia, has completed running and pressure testing the completion string for the acid frac in the M12 well and the well is now ready for the fracturing treatment. Schlumberger are providing the equipment and will perform the stimulation services. As previously announced, mobilisation of the equipment is expected to commence on December 19 and currently everything is on track to complete the acid fracturing and to commence flow testing the well during January 2008.
The objective of the acid fracturing treatment in M12 is to remove near wellbore damage and connect the well with a potential network of natural fractures in the Cretaceous reservoir similar to that observed in outcrop in the area. The effectiveness of acid to stimulate the carbonate reservoir encountered at Manavi has been demonstrated in the laboratory and by the simple low pressure acid matrix treatment undertaken in April of this year. Following that treatment, an increase in flow was obtained from the well with light 40.5o API oil, gas, drilling mud and chemicals flowed to surface. The equipment being mobilised will enable acid and chemicals to be pumped at a sufficient rate to fracture the reservoir beyond any potential damaged zone and hopefully establish proper communication between the well and the reservoir.
The information in this report (including its exhibit) shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (“Exchange Act”), or otherwise subject to liability of that section. The information in this report (including its exhibit) shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing, except as shall be expressly set forth by specific reference in such filing.
