Sintana Energy Inc. is pleased to report 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 ("Patriot"), 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.
