Petro Vista Provides Operational Update

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 17, 2013) - Petro Vista Energy Corp. (TSX VENTURE:PTV) ("Petro Vista" or the "Company"), an independent oil and gas exploration and production company provides the following corporate and operational update.

Approval of Assignment of Participating Interest in Tartaruga Field

The Company and its partners have received official approval from the Agencia Nacional do Petroleo, Gas Natural e Biocombustiveis ("ANP") to the assignment to the Company of a 37.5% participating interest in the Tartaruga Field. The partners, including Petrobras are concluding the execution and filing of amendments to the Tartaruga Concession Agreement and associated agreements.

Operations Update

The operator, UP Petroleo Brasil Ltda, reports continued daily production from well 7-TTG-1DP-SES with minimal decline. This well is currently producing at an average rate of approximately 7,500 barrels of oil per month due to limits imposed by the ANP on gas flaring. The operator has now received approval to install a gas powered turbine generator to be fueled by gas produced from well 7-TTG-1DP-SES and as a result, well production limits will be removed allowing the well to produce at an expected long term stabilized rate of 12,000 barrels of oil per month, using a down hole electric submersible pump (ESP) powered by the generator.

The operator also reports plans to complete a second work over on well SES-107-D including the installation of an ESP. Production from well SES-107-D has been minimal since last year pending completion of this work over. The ESP is on site and a rig has been contracted for the work over.

Board Update

The Company announces that Mr. Ian Baron has resigned from the Board effective immediately. The Company thanks Mr. Baron for his contributions to the Company.

Mr. Baron is replaced by Mr. Nick Walker. Mr. Walker is the COO of Africa Oil Corp. and has over 27 years of industry experience including 17 years with Talisman Energy Inc. where he served as Executive Vice-President of International Operations West as well as country manager positions in the UK and Malaysia/Vietnam.
