Natural gas is regarded as an environment friendly energy to and one of the cleanest forms of fossil fuel energy.Therfor,the development and promotion of natural gas has been has been very active around the world. Although natural gas reserves are widely distributed all over the world,most of these reserves are located in undeveloped areas, far away from consuming cities. A lot of large scale investment will be necessary such as pipeline construction,liquefaction facilities and storage tanks, to bring these reserves to market. Only large scale gas fields have been tapped so far, because they are relatively easy to relatively easy to commercialize, but small or middle scale gas fields have been left undeveloped left undeveloped, due to the economy of scale difficulties.This paper discuss the possibility of natural gas utilization among the Asian-region developing countries, which own undeveloped small or middle scale gas fields.
