1 All evaluations and reviews of future net cash flow are stated prior to any provision for interest costs or general and administrative costs and after the deduction of estimated future capital expenditures for wells to which reserves have been assigned. It should not be assumed that the estimated future net cash flow shown below is representative of the fair market value of the Company's properties. There is no assurance that such price and cost assumptions will be attained, and variances could be material. The recovery and reserve estimates of crude oil provided herein are estimates only, and there is no guarantee that the estimated reserves will be recovered. Actual crude oil reserves may be greater than or less than the estimates provided herein. The estimated values disclosed do not represent fair market value.
2 Effective date: 28 February 2011                
3 Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. There is a less than 10% probability that the quantities actually recovered will equal or exceed the sum of proved plus probable plus possible reserves.
4 Prospective resources are those quantities of oil and gas estimated on a given date to be potentially recoverable from undiscovered accumulations. If discovered, they would be technically and economically viable to recover. There is no certainty that any portion of the resources will be discovered. If discovered, there is no certainty that they will be commercially viable to produce any portion of the resources.

The Company previously had reported net proved and net proved and probable reserves of 223,000 and 413,000 barrels of oil respectively related to the Company's interest in the Morichito Block, Columbia. With the addition of the Tartaruga reserves detailed above, Petro Vista will have increased its proved reserves by 114% and its proved and probable reserves by 173%.

Petro Vista Chairman Keith Hill commented: "We are very pleased with the current rates of oil production from Tartaruga and the recognition of significant quantities of reserves and prospective resources on this Block. The Company will continue to expand its production and operating cash flow base with planned 2011 exploration and development activities on both the Morichito Block and the Tartaruga Block on completion of the assignment of its interest."

Definitions

Proved Reserves are those reserves that can be estimated with high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

Probable Reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved + probable reserves.

Possible Reserves are those additional reserves that are less certain to be recovered than probable reserves. It is unlikely that the actual remaining quantities recovered will exceed the sum of the estimated proved + probable + possible reserves.

Prospective Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective resources have both an associated chance of discovery and a chance of development. Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates, assuming their discovery and development, and may be sub-classified based on project maturity.
