Title: Computer Usages in Recording, Storage, and Analysis of Geological Data: ABSTRACT

Author(s): J. P. Hea, C. D. Conley

Article Type: Meeting abstract


A standard form for logging lithologic characteristics, porosity, and hydrocarbon shows exemplifies systematic data-gathering. This detailed form, used in both desert well-site and laboratory sample descriptions, enables the computer to produce a wide variety of geological maps from data stored on magnetic tapes or disks.

Analysis programs include lithofacies (percentage, constituent, and summary) maps, vertical variability maps, trend-surface analysis, information (entropy) maps, and contouring routines. Data evaluation includes factor and discriminant analysis as well as the more common statistical tests. Economic analysis includes the use of probability and binomial distributions.
