The author has contacted about 50 geoscientists who are using "personal" microcomputers (micros) in their profession. They include respondents to notes in the AAPG Explorer, people referred by members of the AAPG Committee on Computer Applications to Geology, and numerous other members of the AAPG and SEG whose assistance is gratefully acknowledged.

Microcomputers have been widely available for only about five years. Software sophisticated enough to realize their potential has been slow to appear, but a surprising number of geoscientists, including independents and consultants, now wonder how they ever survived without computers. Reported applications areas range from word-processing, production accounting, and financial analysis of prospects to log analysis and creation of synthetic seismograms. System costs range from under $2,000 to over $30,000 plus software.

Explorationists involved in the rapidly growing use of micros are invited to submit their names, addresses, applications, system descriptions, and interests to the Committee on Computer Applications to Geology for inclusion in the next survey mailing. The first survey and mailing list are being made available as part of this paper.
