This paper was presented at the California Regional Meeting of the Society of Petroleum Engineers of AIME in Santa Barbara, California, on October 24–25, 1963, and is considered the property of the Society of Petroleum Engineers. Permission to publish is hereby restricted to an abstract of not more than 300 words, with no illustrations, unless the paper is specifically released to the press by the Editor of the Journal of Petroleum Technology or the Executive Secretary. Such abstract should contain conspicuous acknowledgment of where and by whom the paper is presented. Publication elsewhere after publication in the Journal of Petroleum Technology or Society of Petroleum Engineers Journal is granted on request, providing proper credit is given that publication and the original presentation of the paper.
Discussion of this paper is invited. Three copies of any discussion should be sent to the Society of Petroleum Engineers office. Such discussion may be considered for publication in one of the two SPE magazines.
The time soon may be coming, if not here already, when management in the petroleum industry will find it more difficult to take a firm stand in decision-making which will benefit more the national welfare, the consuming public, or the stockholders. In terms of energy requirements and supply — in fact, in consideration of our entire industry — today's problems seem to demand from both engineers and management a new and clearer perspective.
Why are we looking at the responsibility of engineers and management in the petroleum industry in meeting future energy requirements? We know, at least for the rest of this century, the demand for energy will be tremendous. Many estimates of the magnitude have been quoted by Netschert, Putnam, Ayres, Paley, Hubbert and Wiesner, to mention but a few.
Worldwide, during the next 35 to 40 years, we will use 10Q or nearly as much energy as we have used since Christ was born, which is about 13Q. A Q is a billion billion, or 10(18), Btu. In the next 100 years we will use four times as much as we have used in the last 1,963 years. These are reasonable estimates made by reliable people. I have a hunch these estimates might be low, but even if we cut the estimates in half, the requirements are staggering.
WHERE WILL WE GET THE ENERGY?
Taking a long, long view there seems little doubt that reliance will have to be placed on all of the many sources for energy, with petroleum of less and less importance.
Water power, direct conversion of solar energy, geothermal, and tidal power all will contribute some share of future requirements, as will all of the other known but less widely used sources. In localized areas and for comparatively small special purposes, they will be important. Practical and economic production of nuclear energy itself appears to be a bit down the road. Use of this relatively inexhaustible source for power on a large scale at prices competitive with conventional fuels requires much more research and many technological advances before fission or fusion can provide a substantial share of our energy requirements. Hubbert's scholarly report to the National Research Council covers all of these resources well. Our grandchildren and future generations will be much more concerned with them than we are. Today, taking first things first, we are facing our own responsibilities, not those we are leaving for them.
