Abstract
A method may include obtaining a plurality of historical drilling signals for a plurality of wells. At least one historical drilling signal among the plurality of historical drilling signals describes a drilling surface parameter that is measured during a respective drilling operation. The method may further include generating a first drilling signal while drilling a wellbore through a formation. The method may further include determining a first drilling correlation between the first drilling signal and the plurality of historical drilling signals. The method may further include determining a drilling hazard condition within a well path of the wellbore using the first drilling correlation. The method may further include adjusting, based on the drilling hazard condition, the well path of the wellbore.
