Abstract:
1. A method for displaying a formation model while drilling a wellbore in the formation, comprising: disposing a logging instrument in the wellbore while drilling the wellbore; operating the logging instrument at a measurement point and obtaining measurement data regarding the formation; determining from the measurement data an actual orientation of a geological structure relative to the measurement point; displaying a three-dimensional trajectory of the wellbore as it is being drilled in the formation; displaying, while drilling the wellbore, the geological structure along the trajectory of the wellbore according to the determined actual orientation of the geological structure relative to the measurement point, wherein the orientation reflects an azimuth angle of a plane corresponding to the geological structure; and changing the trajectory of the wellbore in response to displaying the determined actual orientation of the geological structure relative to the measurement point.
