ABSTRACT:
A wellbore perforating apparatus for forming casing or wellbore wall perforations in inclined wellbores includes a perforating gun, a reference unit for determining the high side of the wellbore and a motor for rotating the reference unit and perforating gun to orient the perforation charges at a predetermined angle with respect to the high side and the wellbore axis so as to optimize the angle at which the hydraulic fracture is initiated in the formation. The apparatus includes a motor section with extensible grippers for non-rotatably securing the motor section with respect to the wellbore and for rotating the reference unit and the perforating gun.
