“…Many works focus on the prediction and optimization of the rate of penetration (ROP) using machine learning methods, see e.g., (Sui et al, 2013), (Wallace et al, 2015), (Hegde et al, 2015), (Hegde and Gray, 2017). Others consider the task of predicting the bottom hole pressure, see e.g., (Sui et al, 2011), (Gola et al, 2012), (Sui et al, 2012). In (Roberts et al, 2016) the task of detecting and recognizing a kick is studied from a cognitive point of view; a decision tree is designed to aid the driller in the detection and reaction to the kick.…”
