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.
