CONCLUSIONS 1. Most of the coals embedded in the Carboniferous to Permian and in Jurassic strata are anthracite to meta-anthracite, and total reserves are estimated to be 1.5 billion metric tons. 2. Producible CBM in South Korea is approximately estimated to be 1.3 Tft 3 . 3. Desorption value of anthracite collected at working faces in the SCCF range from 0.5 to 2.3 cc/g gas (dry, ash free basis). 4. In early spring of 2007, the first deep drilling campaign will be launched in order to evaluate and estimate CBM resources in the SCCF.

Assessment of Coalbed Methane Potential in Thailand: A New Project in the Mae La Mao, Mae Sod and Khiansa Basins Wuttipong K., Thawee J. and Sungkom B. Department of Mineral Fuels, Ministry of Energy ABSTRACT: Coal is found in all parts of the country totaling 2,121 million tons of reserves. Coal is a porous medium with relatively low gas permeability and diffusivity. Though coal belongs to the family of reservoir rocks, it differs remarkably from conventional reservoir rocks in that the volume of gas, which it can stores far exceeds its pore volume capacity, the gas being mainly adsorbed onto the pores large internal surfaces. Responding to the government policy in term of sustainable energy, a Coalbed Methane (CBM) project was started in 2003. Three coal basins; the Mae Sod, Mae La Mao and Khiansa Basins have been selected in which to evaluate CBM potential. Both Mae Sod and Mae La Mao are located in the northern part of Thailand. These two basins have been studied by the Department of Mineral Fuels using its own budget. The Mae Sod Basin is studied by the ATOP Technology Company and the Mae La Mao Basin by Chiang Mai University. The drilling results, from 5 wells, are inconclusive. One basin in the south, the Khiansa Basin, has been awarded to SVS ENERGY RESOURCES., LTD., a new Thai petroleum company selected for CBM study since July 2003. Four wells have been drilled but were not successful with relatively thin and split coal seams. However, CBM is still hoped to be one of alternative source of energy in Thailand’s quest for energy sustainability. The Department of Mineral Fuels (DMF) and the Electricity Generating Authority of Thailand (EGAT) have joined to initiate an Oil Shale Project this year in Mae Sod Basin in Tak Province and a CBM project in Fang Basin, Chiang Mai Province, located in the Northern part of Thailand. The objectives of the studies are to determine the reserves, quality and to establish guidelines for the future development of Oil Shale and CBM as alternative energy resources.
