METHOD AND APPARATUS FOR A HIGH SIDE ORIENTING SUB FOR MULTI-LATERAL INSTALLATIONS

摘要

An apparatus for indicating the orientation of a structure which includes an orienting sub (18) releasably connected at an outer case (50). The orienting sub is at a preselected orientation relative to the structure. A change in fluid pressure of a predetermined magnitude of flow rate through the orienting sub will indicate that the structure is at a desired orientation in the well.
