Application of intelligent models in drilling engineering

Recently, intelligent models have become very popular among drilling engineers. These models have aided many researchers to deal with different problems in the area of drilling engineering. In this chapter, a review on the applications of intelligent modelling techniques in drilling engineering is presented. To this end, the published papers are categorized into six different topics, namely, Drilling fluids, Lost circulation problem, Stuck pipe, Flow patterns (FP) and frictional pressure loss (FPL) of two phase flow, Rate of penetration, and Other applications.
