Production Testing Extended to Second CBM Well at Sekayu PSC, South Sumatra

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 15, 2011) - CBM Asia Development Corp. ("CBM Asia" or the "Company") (TSX VENTURE:TCF)(US:CBMDF)(FRANKFURT:IY2) announces that Medco Energi has begun to production test a second well at the Sekayu coalbed methane production sharing contract in South Sumatra. As the Company reported earlier, the CBM-SE-03 well had penetrated over 230 feet of net coal with good gas content. Weatherford International Ltd. is preparing to conduct Coreless Critical Desorption Pressure at the well to measure coal seam gas saturation and gas flow capacity. Weatherford already measured up to 95% gas saturation level (revised up from 93%) in the nearby CBM-SE-02 well, after which flammable gas was produced at surface. The new data will be provided to the Company's Qualified Reserves Evaluator, Netherland, Sewell, & Associates, Inc., for its evaluation of the Company's potential coalbed methane resources at the property, expected in the third quarter 2011.
