Title: Fault Criteria: ABSTRACT

Author(s): Francis F. Campbell (1)

Article Type: Meeting abstract


Examples of six criteria for fault interpretation of seismic data in East Texas and the Gulf Coast are presented on a series of maps and cross sections. The six criteria are: (1) correlation of reflection horizons which bracket the producing objective; (2) projection of a fault from a shallow bed with correlatable reflections to a deep producing objective; (3) variation between geological correlations and geophysical dips; (4) misclosure around a grid unit of seismic control; (5) dip pattern along several lines of control; and (6) diffraction. The diffraction example includes results of fault-model experiments in the laboratory. Although each example was selected as a particularly clear illustration of one criterion, fault interpretation generally depends on a combination of several criteria. Additional criteria for fault interpretation may be used. The criteria presented are not infallible and they do not detect very small faults.
