Map Showing The Study areas (modified after DMR 2001) SCOPE OF STUDY The study of all the above covers the following aspects: 1) Geology of coal deposits The consultant should assemble and study the existing exploration data in order to select drilling sites. The key data used in this study include geological, exploration, well-log and seismic data. 132 New Energy Resources in the CCOP Region - Gas Hydrates and Coalbed Methane
2) Exploratory drilling The consultant proposed the detailed drilling method to the Department of Mineral Fuel. Exploratory drilling must be able to recover soil and rock core samples from depths of over 300 meters. Three wells were drilled, two as observation wells and the other as a production well. Detailed descriptions of soil and rock core samples are made. 3) Well logging Well logging was conducted to study the characteristics of the stratigraphic sequence and coalbed methane as based on gamma ray, density, neutron, resistivity, and spontaneous potential and caliper logs. 4) Analyses Samples were collected, analyzed and studied for various properties of coal beds, soil layers and rock strata including the following aspects: 4.1) Physical and chemical properties of coal beds including heating value, fixed carbon, moisture content, specific gravity, sulfur content and constituent elements. 4.2) Coal petrographic study to determine the composition of organic matter is coal beds, together with determination of vitrinite reflectance to study the burial history of the coal beds. 4.3) Stress conditions were studied to determine distribution of fracture and cleat systems 4.4) Coal permeability was determined. 4.5) The properties and quantity of the methane were determined by a desorption testing. 4.6) The quality of groundwater from coal beds was tested to determine parameters such as salinity, alkalinity electro-conductivity, sulfide-sulfate and variation of trace elements. 5) Gas flow test The gas flow-rate was determined by selecting the coal bed with high potential in methane and performing a well stimulation. 6) Reserve estimation Calculation of reserves of coalbed methane and of coal were based on international standard methods. 7) Groundwater flow system The groundwater flow system was studied for planning of gas production and disposal of waste water generated from the production process. 8) Environmental impact assessment The likely environmental impact of gas production was assessed according to the relevant environmental laws such as management of wastewater from the production process, impact of gas pipeline installation, and power plant development. 9) Development of coalbed methane and commercial benefit Conduct feasibility study to develop coalbed methane and its consequential commercial benefit.
