ABSTRACT:
During directional drilling operation, in order to achieve the correct angle and direction when drilling through a soft formation, a plug of a non-conventional cement is set across the zone in order to achieve the desired course and target. The non-conventional cement is preferably blast furnace slag and a water base drilling fluid.
