Sintana Energy Encounters Gas at Blanco-1 Well

Sintana Energy Inc. has reported the successful execution of drilling operations in the conventional formations encountered by the Manati Blanco-1 well, which is located on the western edge of the 43,158 acre Block VMM-37 in Colombia's Middle Magdalena Basin.

Patriot Energy Sucursal Colombia, wholly owned by the Company, has non-operated participation interests of 100% in the conventional and 30% in the unconventional formations of the VMM-37 Block.



The Manatí Blanco-1 well has drilled through several hundred feet (gross) of porous, conventional channel sands in the Basal Tertiary formation. One sand section was discovered to have up to 90 feet net sand, with gas shows. Logs over these sands indicate high water saturation and a relatively high content of fine-grained material implying low permeability. Preparations to drill into several unconventional shale formations are currently in progress.

Sintana's CEO, Doug Manner, commented: "We are encouraged by initial drilling results to date. It is clear that we have a working hydrocarbon system. The primary targets for this well, and for the entire 67 square miles VMM-37 Block, are the unconventional shale formations. We look forward to updating you in the near future on drilling results for the Manati Blanco-1 well in this high potential impact exploration program."

Additional details of the VMM-37 drilling program will be announced as they become available.

On VMM-4, planning and permitting activities are ongoing for drilling two exploration wells on this 154,904 acres Block. The Company has a 15% participation interest in VMM-4 and will be carried in the initial two wells.

On Talora, three wells have been drilled on two prospects - Verdal and Dorados. Discussions are ongoing to farmout the next phase of a development program. Under a farmout, the Company would be carried for its proportionate share of the costs to reenter the Verdal-2 well and drill underbalanced laterally up to 5,000 feet through the naturally fractured Loma Gorda interval (La Luna equivalent) and conduct flow tests during drilling. The drilling of a twin to the Dorados-1 well would also be included in the carried period of a farmout. The Company has a 30% participation interest in this 34,194 acres Block.
