CBM Asia reports gas to surface from thick, near-saturated coals at Sekayu

Canadian firm CBM Asia Development Corp. announced Wednesday that its partner MedcoEnergi has measured a high degree of coal seam gas saturation in the CBM-SE-02 well at the Sekayu CBM PSC in South Sumatra.

"This test confirms good gas content and high gas saturation in the thick coals present across the Sekayu PSC. Combined with additional gas desorption data anticipated soon from Medco's three deeper test wells, the company expects that its third-party consultant will have sufficient data for evaluating the resources and commercial potential of CBM development at Sekayu," the company said

Well-site contractor Weatherford International Ltd. conducted Coreless Critical Desorption Pressure testing on the 36-foot thick Pandangan A coals within the 1,710- to 1,793-foot depth interval. Coal seam gas content was measured at approximately 100 scf/ton (dry, ash-free basis), with an estimated 93% level of gas saturation. Gas composition has not yet been determined but the gas being produced to surface is flammable.

MedcoEnergi subsequently installed a downhole pump in the well and has begun a short-term test to dewater the coal seams. Already, a small amount of gas is being produced to the surface from these still unstimulated coal seams, it added.

Medco is the operator of Sekayu CBM PSC with 50 percent interest.(alex)
