Claim 10:
11. A method for controlling drilling, comprising:
receiving, by a computer system coupled to a drilling rig, during drilling of a second borehole, a drilling trajectory of the second borehole relative to a previously-drilled first borehole;
receiving, by the computer system, from at least one magnetic sensor associated with a bottom hole assembly (BHA) located in the second borehole, data associated with a current spacing between the second borehole and the first borehole;
receiving, by the computer system, a trajectory of the first borehole;
responsive to the drilling trajectory of the second borehole, the trajectory of the first borehole, and the data associated with the current spacing, forecasting, by the computer system, a target path for the second borehole spaced relative to the first borehole and having a selected spacing from the first borehole, the target path based on the drilling trajectory of the second borehole, the trajectory of the first borehole, and the data associated with the current spacing wherein the target path for the second borehole is associated with a value having an asymmetrical variance such that the value increases at a higher rate when the second borehole is within a selected distance from the first borehole;
updating, by the computer system, the drilling trajectory for the second borehole responsive with the target path;
sending, by the computer system, control information to a control system coupled to the drilling rig to drill the second borehole according to the updated drilling trajectory with the target path; and
drilling a portion of the second borehole in accordance with the updated drilling trajectory with the target path.
