Claim 0:
1. A method, comprising:
defining total depth coordinates of a candidate wellbore path within a hydrocarbon reservoir;
obtaining geoscience data for a subterranean region enclosing the hydrocarbon reservoir;
obtaining historical drilling data from an offset well in the subterranean region;
training a machine learning network to predict drilling hazard probabilities along the candidate wellbore path using the geoscience data and the historical drilling data;
determining a first wellbore path to terminate at the total depth coordinates using the candidate wellbore path and the trained machine learning networks;
drilling a first portion of the first wellbore path;
obtaining first drilling data from drilling the first portion;
re-training the machine learning network using the first drilling data, the geoscience data, and the historical drilling data; and
determining a second wellbore path using the re-trained machine learning network.
