If an optical televiewer log is required, and the rock portion of a borehole must be flushed clean, it is recommended that PVC casing be used to keep the soil portion (if any) of the borehole open.
Get MoreDirectional drilling is a broad term used to describe any boring that doesn't go in a straight line vertically down. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. In this instance, the driller uses sidetracking techniques.
