Abstract: A method of modeling a wellbore path in an earth model, including receiving, from an electronic drilling recorder coupled to a bottom hole assembly (BHA), a set of BHA data, and a set of operating parameters data and receiving, a set of rock formation data; generating, a representation of a wellbore path in a first section of the earth model, by assessing the set of BHA data, the set of operating parameters data, the set of rock formation data, and a first set of parameters quantifying bit steerability, walk, coefficient of friction, and overgauge borehole information. The method includes modifying, based on data received from a survey corresponding to the first section of the earth model, the first set of parameters to generate a second set of parameters, and generating a future wellbore path in a second section of the earth model by applying the second set of parameters.

Abstract: A method for detecting a malfunction during a drilling operation is carried out by making use of a drill bit, the method including the following: a) the comparison of a first magnitude (E) representative of the mechanical specific energy (MSE), with a first threshold value (Emax); b) when the first magnitude is greater than the first threshold value, the comparison of the ratio (E/S) between the first magnitude and a second magnitude (S) representative of the drilling force with a second threshold value ((E/S)max); c) the detection of a malfunction in the drilling operation when the ratio (E/S) between the first magnitude (E) and the second magnitude (S) is greater than the second threshold value ((E/S)max). The method provides the ability to ensure more precise detection of a malfunction during drilling operations.
