– Indonesia’s first commercially drilled coalbed methane test well went to a TD of 1,950 ft in South Sumatra, cut a combined 90 ft of coal in five seams, and was cased to 878 ft. Ten more wells are planned by the end of 2009.

Operator PT Medco Energi Internasional Tbk, PT Ephindo of Indonesia, and CBM Asia Development Corp., Vancouver, BC, drilled the CBM-SE-02 well in the 58,349 ha Sekayu production sharing contract block.

Thicknesses are 20 ft in Palembang C, 40 ft in Palembang B, and in the lower Maura Enim unit, three seams totaling 30 ft of coal in Pangadang A. Medco shipped core from all five seams to the Geological Agency of Indonesia in Bandung, where gas content and saturations will be determined. An injection falloff test was successfully run in Palembang B to assess permeability.
