The demand of energy is increasing over time, diversification is one of the emerging approaches to fulfill the demand. Unconventional energy source has been developed by many researchers, those energy include CBM, geothermal energy, shale gas and oil, and one that considerably important is methane hydrate. Preliminary exploration of methane hydrate in Indonesia was minor. Methane hydrate requires a specific condition to be accumulated. Combination of temperature, pressure, and methane source are crucial as the main pre-requirement of methane hydrate accumulation. Such conditions are important to be mapped due the future energy challenge. By compiling bathymetry and sedimentary basin map with specific information and supported by literature data, it is possible to delineate methane hydrate potentials in Indonesia. Bathymetry maps can be used to refer physical condition such as temperature and pressure on sea-floor where methane hydrate should be accumulated. Sedimentary basin map gives information about the possible methane sources respect to sediment source and possible working petroleum seepage. Using specific technique which is widely used by several researchers such as Majorowicz and Osadetz (2001), maps of methane hydrate potential in Indonesia can be created. The techniques involves the determination the depth that is suitable for a trapping system of methane hydrate, determination of the possible sources, and the overlaying between both condition to delineate the possible areas. Hydrate methane potential map can be used to delineate potential area, this map contains information about how should hydrate methane accumulated within those area, the source and area covered.
