DENVER, CO–(EMWNews – July 29, 2008) – Sentry Petroleum (OTCBB: SPLM) announced today

the formal hiring of independent oil and gas consultancy MBA Petroleum

Consultants as the company’s independent evaluator. MBA Petroleum

Consultants is a leading international consultancy that uses

state-of-the-art technology for assessing the hydrocarbon potential of

exploration assets. The company also provides Independent Expert Reports

for use in listing submissions to exchanges such as the AIM in London and

the Australian Stock Exchange.

Dr. Rajeswaran, Sentry Petroleum President, commented, “MBA and its

principal founders, Doug Barrenger and Wal Muir, enjoy excellent

reputations within the oil industry; MBA is thorough in its analysis and is

independent. Their expertise and independence will provide our

shareholders, investors and industry partners an unbiased assessment of our

assets and potential.”

Commenting on Sentry Petroleum’s assets, Wal Muir, founding partner of MBA

Petroleum Consultants, noted, “Oil and gas were previously discovered and

produced at the Gilmore Field. This play in the Devonian sequences of the

Adavale Basin has been ignored in recent years, yet is a proven hydrocarbon

system. Sentry and MBA are confident that this reappraisal of the basin

will lead to drillable prospects being mapped.”

A Sentry spokesperson advised that MBA Petroleum Consultants is currently

sourcing and loading over 3,400 kilometres of seismic data. These seismic

data will then be integrated with the information from wells drilled within

and near the permit and interpreted using new ideas for plays developed by

both Sentry and MBA.

Dr. Rajeswaran concluded, “Doug has more than 26 years’ experience in the

petroleum industry and has undertaken all facets of geological work, from

wellsite operations to prospect evaluation, risk analysis and basin

analysis. Wal Muir has over 28 years’ experience in the petroleum industry

and specializes in the evaluation of the value and risks associated with

exploration acreage. He has specific experience in the Adavale Basin and

understands the intricacies of its complex geological setting. His skills

in seismic interpretation, risk analysis, play and prospect evaluation will

provide Sentry and our shareholders a degree of expertise unavailable

anywhere else in the world.”
