Claim 0:
1. An apparatus associated with a drilling rig, comprising:
a computer system configured to be coupled to a drilling rig for controlling drilling of a second borehole relative to a previously-drilled first borehole, wherein the computer system comprises:
a processor;
a memory coupled to the processor, the memory storing a plurality of non-transitory computer readable instructions for execution by the processor, wherein the instructions comprise instructions for execution by the processor to, during drilling of the second borehole by the drilling rig:
receive first historical information about the first borehole and second historical information about the second borehole, wherein the first historical information and the second historical information comprises one or more of drilling speed, weight on bit, differential pressure, and toolface orientation;
receive information from a downhole magnetic sensor and determine a current spacing between the second borehole and the first borehole and a current position of the second borehole;
generate, based on the received first historical information, the received second historical information, and the current position of the second borehole, a plurality of solution paths of the second borehole relative to the first borehole from the current position of the second borehole, each solution path associated with a value, wherein the value varies asymmetrically with respect to a distance between the first borehole and the second borehole;
compare the value associated with each of the solution paths and identify one solution path from the plurality of solution paths as a target path based on the value of the identified one solution path, wherein the one solution path has a lowest cost for drilling the second borehole and provides a desired spacing of the second borehole relative to the first borehole;
send control information to a control system of the drilling rig, the control information to control one or more drilling parameters; and
drill the second borehole in accordance with the target path.
