Petro Vista Cancels Equity Financing

SAN CLEMENTE, CALIFORNIA--(Marketwire - Aug. 14, 2008) - Petro Vista Energy Corp. (TSX VENTURE:PTV) (the "Company"), has elected, due to adverse market conditions, to withdraw its private placement equity financing that was announced on July 4, 2008. Petro Vista does not feel that the current share price accurately reflects the value of the Company.

Given the current circumstances, the Company has reviewed its cash position and its upcoming commitments and is in a position to continue with its business activities as planned.

The Company estimates it has sufficient funds to pay all costs associated with drilling and completing up to four wells on its La Maye Project in the Magdelena Basin, Colombia; completing the drilled and logged well #2 (with pay determined from petrophysical analysis) on its Morchito Project in the Llanos Basin; and completing the acquisition of a 30% interest in the producing Tartaruga Block, offshore Brazil.
