TORONTO, ONTARIO - October 22, 2013 - Sintana Energy Inc. (TSX-V: SNN) ("Sintana") announces that it has commenced an arbitration action, through the International Chamber of Commerce in Paris, France, against Petrodorado Energy Ltd. (TSX-V: PDQ) and Petrosouth Energy Corp., the Operator, (together "Petrodorado") relating to the Talora Block located in the Magdalena Basin, Colombia ("Talora Block").

Sintana and Petrodorado entered into a Farmout Agreement dated October 16, 2011 ("Agreement") to further the exploration and development of the Talora Block. Sintana contends that Petrodorado committed multiple breaches of the Agreement.

Since the commencement of this dispute, it has been the strong preference of Sintana to amicably reach an acceptable compromise and preserve the Agreement. These attempts have proven unsuccessful. Accordingly, Sintana has referred the matter to arbitration and will vigorously pursue its claims in accordance with the terms and conditions of the Agreement.

On behalf of Sintana Energy,

"Doug Manner"
Chief Executive Officer
