Petro Vista Provides Operational Update

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. He started his career as a petroleum engineer with BP plc, and
also worked in senior management positions at Bow Valley Energy Inc. Mr. Walker
holds a Bachelor of Science Degree in Mining Engineering from Imperial College
in London, UK, a Master of Science Degree in Computing Science from University
College in London, UK and an MBA from City University Business School, also in
London, UK. 


Petro Vista's Chairman Keith Hill commented, "We are very pleased to announce
the appointment of Mr. Nick Walker, whose operational experience will be
invaluable as Petro Vista continues to develop the Tartaruga Field and look at
new Ventures. Being cash flow positive with approximately $1M in cash on hand
and a further $700,000 in accrued revenues in Brazil to fund the second work
over, the Company is well position to review strategic alternatives".
