Potential employment opportunities for displaced aerospace and defense technical personnel in the petroleum industry were studied for the U.S. Department of Labor. A relatively small, but increasing number of ex-aerospace and defense personnel can be absorbed by the industry, beginning with from 40 to 100 jobs in 1972 and increasing each year to 100 or 150 by 1975. A pilot training program offered in conjunction with a cooperative petroleum or support company would qualify these displaced professionals for opportunities in the petroleum field. The occupational demand for electronic engineers in the fields of instrumentation, computers, control systems, and other engineering and scientific applications will increase in the next few years. With the increasing automation of the petroleum industry, the requirement for highly complex electronic systems is increasing. Possibilities also exist in reliability analysis, quality control, special materials fabrication, and control systems. Principal points of opposition to the employment of displaced aerospace professionals from the petroleum industry are identified. Related chapters are available as VT 018 435-018 451 in this issue.
