Abstract

Methods and systems for wellbore path planning are disclosed. The method includes defining total depth coordinates of a candidate wellbore path within a hydrocarbon reservoir, obtaining geoscience data for a subterranean region enclosing the hydrocarbon reservoir, and obtaining historical drilling data from an offset well in the subterranean region. The method further includes training a machine learning network to predict drilling hazard probabilities along the candidate wellbore path using the geoscience data and the historical drilling data. The method still further includes determining a first wellbore path to terminate at the total depth coordinates using the candidate wellbore path and the trained machine learning network.
