Engineering and Economics of Long Oil Pipelines

The use of pipeline-c to carry crude'oil and petroleum pro-ducts is a reliable and economic*Way to transport large quantities of oil. The length and size of these pipelines have continued to grow throughout the world as the demand for petroleum has in-creased and as the price of other transportation-methods has risen. At the present time pipelines 'can move a barrel of oil a distance of 100 miles at an average cost of ,80.06 U.S. dollars.The major elements in pipeline design are discussed. Methods of calculating pressure drop and horsepower requirements are pre-sented. These are variations of standard equations.in which the elements of each equation are expressed in terms common to the petroleum industry. Major equipment is discussed., particularlyas it relates to operation and economics.Cost data are presented to aid in preliminary economic ana-lysis. Curves illustrate the cost of oil transportation at flow rates between 10,000 and 500,000 barrels per day and permit the selection of pipe diameter-which will result in minimum operating costs.
