Claim 16:
17. A system, comprising:
a computer system configured to:
receive total depth coordinates of a candidate wellbore path within a hydrocarbon reservoir;
receive geoscience data for a subterranean region enclosing the hydrocarbon reservoir;
receive historical drilling data from an offset well in the subterranean region;
train a machine learning network to predict drilling hazard probabilities along the candidate wellbore path using the geoscience data and the historical drilling data;
determine a first wellbore path to terminate at the total depth coordinates using the candidate wellbore path and the trained machine learning network; and

a drilling system configured to drill the first wellbore path,
wherein the computer system is further configured to:
re-train the machine learning network based, at least in part, on first drilling data obtained using the drilling system to drill a first portion of the first wellbore path, and
determine a second wellbore path using the re-trained machine learning network.
