Sintana Energy Inc. (TSX-V: SNN) ("Sintana" or the "Company") announces that it has been notified by the Operator of the Talora Block that the Dorados-1X exploration well commenced drilling operations on July 31, 2012.

The Company previously announced an agreement with Petrodorado Energy Ltd. (TSX-V: PDQ) to farm-in for an undivided 30% interest in the 58,570 acre Talora Block located in Colombia's prolific Magdalena Basin. The Talora Block, which is operated by Petrodorado, is immediately adjacent to the region's main oil and gas pipelines and only 60 kilometers west of the capital city of Bogota. Given this close proximity to infrastructure, conversion of a discovery to a commercial well is expected to be a relatively quick process.

The well, which is targeting the Cretaceous Caballos and Tetuan formations, is presently drilling ahead at a depth of 2,500 feet to a planned total depth of 9,500 feet. The Company will earn a 30% private participation interest in the well by paying 60% of the well costs, subject to a cap of US$6.5 Million (gross). Costs above the cap are to be paid proportionally by each partner based on their respective participation interests.

In Peru, planning has commenced for a seismic program on Bayovar Block XXVII (Sintana – 25%), located in the Sechura Basin. Faulkner Exploration, as operator, previously drilled the SC-4X seismic control well. Open hole log data from the well is being incorporated into the design of the seismic shoot. Post processing and analysis, optimum locations for subsequent wells will be selected based on this seismic.

The SC 4X control well reached a TD of 5,276 feet and encountered the target reservoirs 500 feet lower than anticipated. Open hole log evaluations identified a continuous column of rich gas shows from the 1,496 feet of gross Paleozoic section penetrated, starting at 3,780 feet. Imagery logs depict a high density fracture system with a network of fracture intersections. The Operator reported that during testing the highly fractured target interval collapsed which prevented completion of the well. The objective of gathering open hole log data on the stratigraphic section on the block was achieved and indications of hydrocarbons at this location are considered a significant bonus.

Doug Manner, CEO of Sintana commented "We are excited about commencing the Talora exploration drilling program and look forward to completing the seismic program at Bayovar. We anticipate having drilling results for the Dorados-1X well in September."
