ABSTRACT:
Steering behavior model can include build rate and/or turn rate equations to modal bottom-hole assembly behavior. Build and/or turn rate equations can be calibrated by adjusting model parameters thereof to minimize any variance between actual response118and estimated response produced for an interval of the well. Estimated position and orientation104of a bottom-hole assembly along a subsequent interval can be generated by inputting subsequent tool settings into the calibrated steering behavior model. Estimated position and orientation104can be compared to a well plan106with a controller108which determines a corrective action110. Corrective action110can be converted from a build and/or turn rate to a set of recommended tool settings114by using an inverse application112of the steering behavior model. As additional data118becomes available, steering behavior model can be further calibrated102through iteration.
