METHOD TO DETERMINE A TIME-DEPTH MODEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18059915 titled 'METHOD TO DETERMINE A TIME-DEPTH MODEL
Simplified Explanation
The method described in the patent application involves drilling a wellbore to various depths within a subterranean region of interest and obtaining seismic data at each depth to create a coherency map. This map is used to determine unique seismic velocities and vertical travel times, which are then used to generate a vertical travel time-depth model and convert time-domain surface seismic data to depth-domain surface seismic data.

Original Abstract Submitted
Systems and methods are disclosed. The method includes drilling, using a drill bit, a wellbore to a sequence of drilling depths within a subterranean region of interest. The method further includes, for each drilling depth, obtaining a seismic dataset generated by the drill bit, determining a coherency map using the seismic dataset, a range of seismic velocities, a range of vertical traveltimes, and a geological model, determining a locus from the coherency map, defining an objective function based on the locus, and determining a unique seismic velocity and a unique vertical traveltime based on an extremum of the objective function. The method further still includes generating a vertical traveltime, depth model using the unique seismic velocity and the unique vertical traveltime for each drilling depth, obtaining a time-domain surface seismic dataset, and determining a depth-domain surface seismic dataset using the time-domain surface seismic dataset and the vertical traveltime, depth model.
