Claim 0:
1. A system for guiding a drilling rig using a subsurface model, said drilling rig comprising at least a drill and a drill control unit, the system comprising:
at least one surface sensor positioned on a ground surface at a distance from said drilling rig, wherein said at least one surface sensor is configured to detect surface seismic data;
at least one subsurface sensor coupled to said drill, wherein said at least one subsurface sensor is configured to detect subsurface seismic-while-drilling (SWD data when said drill is in operation; and
a server operatively connected to said at least one surface sensor and to said drill control unit,, and wherein server is configured to process said surface seismic data using a first full waveform inversion (FWI) to thereby produce a first approximation of a subsurface surrounding said drill,, and wherein said server is further configured to process said first approximation, said SWD data, and a drillbit source signature related to said drill using a second FWI, to thereby produce said subsurface model,, and wherein said subsurface model is used to guide said drilling rig.
