Abstract

Two expert systems are studied here. One is the expert system for validation of seismic stacking velocity functions. The other is the expert system for seismic interpretation. Velocity Expert System (VELXPERT) is to find knowledge representations and inference techniques that are appropriate for the seismic stacking velocity analysis problem domain and to use these representations and techniques to develop a prototype expert system for seismic stacking velocity validation that can detect several common errors and rate the quality of a given velocity function. The Seismic Interpretation Expert System (SIES) is an attempt to apply expert system techniques in building a system to assist seismic interpreters. SIES is a backward-chaining system using symbolic pattern matching and streams of association lists with certainty factors to allow inexact reasoning. Rules in the knowledge base were built upon seismic stratigraphy methods and seismic interpretation knowledge to determine sub-surface features. As a prototype, SIES illustrates how an expert system using pattern matching and streams can be used to make inferences and represent knowledge in a domain as complex as seismic interpretation.
