Claim Text:
1. A computer-implemented method for modeling passage of an elongate well tool through an interval of a well, the method comprising: receiving, with an adaptive machine learning model executed on a computing system, a first set of inputs representing a plurality of characteristics of the well tool and a second set of inputs representing a plurality of characteristics of the well, the well comprising a wellbore formed from the Earth's surface through one or more geologic formations to a subterranean zone, and the well tool positioned on a downhole tool string residing in the wellbore; receiving, with the adaptive machine learning model, historical data representing a plurality of other well tools passed through a plurality of other wells and a plurality of characteristics of the other well tools and the other wells; matching, with the adaptive machine learning model, the historical data with at least a portion of the first and second sets of inputs; determining, with the adaptive machine learning model, whether the well tool can pass through an open space proximate the interval of the well based on matching the historical data with the portion of the first and second sets of inputs; receiving, in real time as the well tool is conveyed through the wellbore, a determination from a mathematical model of whether the well tool can pass through the open space proximate the interval of the well, the mathematical model operating separately and in parallel to the adaptive machine learning model, such that the determination from the mathematical model is independent of the determination from the adaptive machine learning model; comparing the real-time mathematical model determination of whether the well tool can pass through the open space proximate the interval of the well with the adaptive machine learning model determination of whether the well tool can pass through the open space proximate the interval of the well; and based on the comparison, outputting a probability value of whether the well tool can pass through the open space proximate the interval of the well.
