The tremendous demand, for natural gas and the competence of American entrepreneurs utilizing innovations to satiate this demand have made the development of natural gas transmission pipelines one of the most inherent elements of our national economy. With increasing prices of coal and oil, natural gas has became the cheap fuel as veil as the choice fuel, throughout the nation thousands of miles and more from the veilhead. This thesis is concerned vlth the most exciting part of the natural gas industry—that which deals with the long distance pipelines crossing rivers, plains, deserts, swamps and mountains to carry gas from the producing fields to markets far away. Maturity In this phase of transportation has lagged behind water, rail, motor and air. And since a scarcity of information exists as to what important steps are necessary to the development and operation of natural gas transmission lines, the author has endeavored to determine and explain the Integral steps requisite to the development of a natural gas transmission system. The primary source of information vas derived from thirteen years experience working throughout the organization of one of the giants in the industry. In addition, numerous hours of research were spent in order to set the historical background of the subject. Several interviews were also conducted with men associated with the industry from the lowest echelon to the top. Conclusions indicate that the spontaneous demand, for natural gas has taken on characteristics of a runaway market. Such a widespread and strong preference for natural gas as a fuel of premitaa quality has resulted in the construction of additional pipelines in order to increase its availability in both existing markets and others not previously served. In many markets served by long distance pipelines of limited capacity, inability to meet the tremendous consumer demands for both domestic and industrial purposes is the foremost problem facing the natural gas transporters. Estimated proved reserves of natural gas as related to current production indicate approximately a thirty year supply. The trend of this ratio will depend, however, upon the magnitude of additional discoveries in relation to future consumption levels, lhere appears to be no reasonable prospect that natural gas can generally displace coal as industrial fuel, even though present price relationships are widely conducive to its choice. On the other hand, the market prospects of the natural gas industry are now almost unlimited with respect to the residential and industrial fuel markets in which it can eearpete with coal and oil. Thus, as gas builds to shoulder an increasing share of the total energy load, it will continue to be the fastest growing member of the entire energy family.
