Sentry Petroleum Ltd. (OTCBB: SPLM) has reported that Denver-based Coal Ltd.’s coal seam gas expert Dr. Charles Barker has confirmed the potential ‘world-class’ coal seam gas deposit within Sentry’s ATP 862 and ATP 864.

Dr. Barker’s exhaustive assessment included analysis of all publicly available data and proprietary testing covering Sentry’s previously identified potential 2,000 square-mile coal and shale gas prospect underlying its northern permits in Queensland Australia. His conclusion: over 10 trillion cubic feet (Tcf) of prospective gas resource in place.

"My review of the data focused on a 300 square-mile area surrounding previously drilled wells," said Barker. "This area provided the greatest well control and interpretable data upon which to base my independent assessment. It is my judgment that the potential coal seam and shale gas deposit could be well in excess of 2,000 square-miles previously reported by Sentry’s technical team. In my view there exists substantial upside to the 10 Tcf of prospective gas resource estimate that I have provided to Sentry’s executive board."

Barker confirmed that technical data from over thirty wells and Sentry’s interpretation of a regional grid of seismic data indicate the Winton coal zone underlies a greater than previously reported 2,000 square mile area. The coal rank was analyzed to reach sub-bituminous to high volatile bituminous in the deeper portions of the deposit. He further confirmed the coal characteristics of the Winton coal zone closely resemble the depth to coal, coal rank, gas storage capacity and net coal thickness found in portions of the prolific Powder River Basin in Wyoming and Colorado.

"My initial excitement on the potential deposit has been confirmed," Barker concluded. "If my estimates are proved correct and the gas is economically recoverable, Sentry is sitting on a multi trillion cubic foot gas asset. All that remains is to test this large indicated coal and shale based prospective resource. It is at optimal production depths and if it is gas saturated it will certainly be a world class deposit in excess of trillions of cubic feet."

A company spokes person advised that Sentry is moving expeditiously on its drilling program scheduled to start in April/May 2011. Discussions have commenced with several independent petroleum consulting firms to assist Sentry in determining optimum appraisal program in order to provide reserve certification.
