Virtual-Intelligence Applications in Petroleum Engineering: Part 3—Fuzzy Logic

The focus of this article is fuzzy logic. The article provides overview of the subject and its potential application in solving petroleum-engineering-related problems. As the previous articles, the most successful applications of intelligent systems, especially when solving engineering problems, have been achieved by use of different intelligent tools in concert and as a hybrid system. This article reviews the application of fuzzy logic for restimulation-candidate selection in a tight-gas formation in the Rocky Mountains. We chose this particular application because it uses fuzzy logic in a hybrid manner integrated with neural networks and genetic algorithms.
