Image based stick slip correction of logging while drilling images
Abstract:
A method for correcting an LWD image to remove stick slip features includes obtaining an LWD image in a wellbore. Surface depth measurements may be interpolated to obtain interpolated surface depths at selected ones of the depths in the LWD image and evaluated to obtain a first tool status log. The LWD image may be evaluated to obtain a second tool status log. The two status logs may be synchronized to obtain a synchronized log. A stick slip feature may be identified in the LWD image and the image resampled to remove the stick slip feature from the LWD image.
