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 responseand estimated response produced for an interval of the well. Estimated position and orientationof 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 orientationcan be compared to a well planwith a controllerwhich determines a corrective action. Corrective actioncan be converted from a build and/or turn rate to a set of recommended tool settingsby using an inverse applicationof the steering behavior model. As additional databecomes available, steering behavior model can be further calibratedthrough iteration.
