FORTRAN IV Program for Simulating Geologic Development of Sedimentary Basins

Abstract

A FORTRAN IV program is described for simulating geologic processes involved in the development of oil traps. Deposition, diastrophism, compaction and erosion can be defined mathematically and the structural highs within the three-dimensional model located.

The geology of the model area is gridded manually into a regular pattern and described in algebraic terms. Time is segmented by defining basement topography and then the geologic events as they are believed to have occurred. Experimentation with different hypotheses may be required to approximate the observed geology.

Visual displays can be specified at any time during the model development, permitting analysis of results before continuing with succeeding events. Displays include listings of geologic columns, structural elevations, and isopachous intervals and CALCOMP-plotted stratigraphic cross sections.
