Paper presented at the SPWLA 60th Annual Logging Symposium, June 15–19, 2019
Paper Number: SPWLA-2019-TTT
... for validation. First, we discuss a particular clustering procedure termed PMVCA (Probabilistic Multi-Variate Clustering Analysis) that is used in conjunction with an Expert System to identify and classify first Electroclasses and then, second, Lithologies. The difference between these terms is explained...

Paper presented at the SPWLA 34th Annual Logging Symposium, June 13–16, 1993
Paper Number: SPWLA-1993-YY
... ABSTRACT This paper describes the prototype of a hybrid expert system; Slip Expert is used for estimating the slip velocity of multiphase flow in a producing well. The system consists of five components: OSF/Motif based front-end user interface, inference engine, knowledge base, model base...

Paper presented at the SPWLA 33rd Annual Logging Symposium, June 14–17, 1992
Paper Number: SPWLA-1992-II
... ABSTRACT This paper gives an overview of state-of-the-art production logging interpretation techniques. Existing approaches to production logging interpretation are classified into four categories: physical modeling, statistical modeling, empirical, and expert system approaches. Techniques...

... of pattern recognition and expert system techniques shows some potential. We are exploring this problem by beginning at the computerized stratigraphic interpretation. Following the logic of human experts, the task is divided into two sub-tasks: contact recognition and geo-interpretation. The entirety...
