Abstract: The expert system SFAES introduced in this paper implements the interpretation of seismic facies in which human intelligence is involved.The system can recognize and analyse various reflection configurations.The results produced are consistent with what human expert expects.We utilize ES method in developing this system.The knowledge of interpretation can be added conveniently.A control method called blackboard architecture is used in the system.Our practical experience has proved that the blackboard is a powerful method in solving some complex problems.The research on SFAES creates favourable background to develop the knowledge processing system for interpretation of seismic data.
