<br />. ..;'. . <br /> <br />-5- <br /> <br />Dr, Decora had given his definition of the energy balance input-output <br /> <br />formula at a recent meeting of the Department of Interior Environmental Advisory <br /> <br />Panel for oil shale at Park City, Utah. In explaining why he agreed with the <br /> <br />Decora analysis, Berry pointed out that Rio Blanco will purchase electricity <br /> <br />and ammonium nitrate for blasting as the only exterior sources of energy. Diesel <br /> <br />fuel for operation of the trucks likely will be produced from the shale oil <br /> <br />itself. Process heat required for the operation of the retorts and upgrading <br /> <br />equipment will either come from burning a portion of the shale oil or some of <br /> <br />the retort gasses. The gaseous hydrocarbons required as process feed for the <br /> <br />steam-crocking generation of hydrogen will be a fraction of the retort and <br /> <br />upgrading gasses. <br /> <br />Berry took issue with those who say shale oil would supply only 3% <br /> <br />of the nation's energy requirements. He noted that the transportation sector <br /> <br />of the U. S. economy consumes about 25% of the total energy requirement. There- <br /> <br />fore, shale oil at 3% of the total, represents a very significant 12% of the <br /> <br />transportation segment. And, for this part of energy needs, other energy <br /> <br />sources such as coal wont work, he said. <br /> <br />He also pointed out that a one million barrel per day shale oil <br /> <br />industry providing oil at today's price for imported oil would save the United <br /> <br />States some $4 billion per year in foreign exchange. <br /> <br />In reviewing water needs for the C-a oil shale program, Fred V. <br /> <br />Witaschek, Senior Staff Engineer for Gulf Energy and Minerals Co., said that <br /> <br />the project would need some 60,000 acre feet of water annually if the shale oil <br /> <br />program is successful and eventually reaches production of 300,000 barrels of <br /> <br />oil per day. He said this water may come from a combination of groundwater <br /> <br />(\223 <br />
