Claim 19:
20. Non-transitory computer-readable media having encoded thereon computer-readable and computer-executable instructions that, when executed, implement a method for guiding a drilling rig using a subsurface model, wherein said drilling rig comprises at least a drill, a drill support structure, and a drill control unit, and wherein said drill is positioned below a ground surface when said drill is in operation, the method comprising the steps of:
obtaining surface seismic data using at least one surface sensor positioned on said ground surface at a distance from said drilling rig;
processing said surface seismic data using a first full waveform inversion (FWI) to thereby produce a first approximation of a subsurface surrounding said drill;
obtaining seismic-while-drilling (SWD) data from at least one subsurface sensor coupled to said drill;
determining a drillbit signature;
processing said first approximation, said drillbit source signature, and said SWD data using a second FWI to thereby produce said subsurface model; and
using said subsurface model to guide said drilling rig.
