Abstract: A method includes receiving at least one drilling condition input from at least one sensor of a drilling rig, obtaining a first slide mode determination based at least partially on a rotational speed of a drill string, obtaining a second slide mode determination based at least partially on torque applied to the drill string, selecting one of the first or second slide mode determinations based on the at least one drilling condition input, determining that the drilling rig is in slide mode based on the selected one of the first or second slide mode determinations, calculating at least one steering parameter based at least in part on determining that the drilling rig is in slide mode, and executing at least one drilling operation based in part on the at least one steering parameter.

Abstract: A system and method that may include receiving real-time downhole data from one or more sensors of a drillstring disposed in a borehole in a subsurface geologic region during a directional drilling operation. The system and method also include selecting a drillstring drilling mode from a plurality of drillstring drilling modes. The system and method may additionally include predicting, in real-time, characteristics of a hole bottom of the borehole using the drilling mode model and at least a portion of the real-time downhole data. The system and method may further include controlling the directional drilling operation using one or more of the characteristics.
