Considering countries with a large territorial area, an obstacle for the expansion of the natural gas market consists in the lack of infrastructure for its transportation. Several alternatives were considered to create local demand for gas, e.g., transportation in trucks as CNG or LNG or even the traditional pipelines. An adequate selection of the modal will tend to reduce the transportation costs involved. A technical discussion of the implications of each one of the alternatives and the transportation logistics is presented. An economical comparison among the different models as function of the amount of gas to be transported and as function of the distance is also presented. This is an abstract of a paper presented at the 19th World Petroleum Congress (Madrid, Spain 6/29/2008-7/3/2008).
