Petro Vista Energy Corporation: Morichito #1N Test Results

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 15, 2009) - Petro Vista Energy Corporation (TSX VENTURE:PTV) ("Petro Vista" or the "Company") and its wholly owned Colombian subsidiary, Petropuli Ltda ("Petropuli"), announced today test results from the Morichito #1N well located within the Morichito Block in the Llanos Basin in Colombia. Good oil shows were encountered while drilling and log data indicated several potential pay zones, however, upon testing these zones proved to be water wet.

Six zones, including the Paleozoic, Cretaceous Ubaque, Gacheta and Tertiary Carbonera C7 were tested. Though water wet, all zones, with the exception of the Paleozoic, indicate good reservoir development and the Company looks forward to drilling its next Morichito well on this promising prospect. The Company was fully carried on this well and also will be partially carried on the next well pursuant to farm-out agreements reached earlier in the year.

The Morichito #1N well was the first of a two-well commitment the company has on its Morichito exploration license with the Colombian National Hydrocarbon Agency. There remain several strong leads and prospects on the block and a full evaluation will be carried out over the next few months in preparation for the next well.

Colombia is an important oil and gas producing nation and Petro Vista holds a large acreage position in the country's key producing regions. In addition to its work in the Morichito block, the Company will commence exploration activities over the next few months on its La Maye block in the prolific La Magdalena basin of northern Colombia.
