Abstract
A fracture oriented completion tool system for use in a casing string in a wellbore. The completion tool comprises a casing valve having a radioactive source therein, the orientation of which may be determined by use of a detector apparatus, such as a rotational gamma ray detector. The casing valve thus may be aligned with the fracture of a zone of interest in the well. A plurality of casing valves may be used, with at least one having a radioactive source. A swivel connection may be used to interconnect the casing valve so that housing ports therein may be aligned as the casing is run into the wellbore. In one preferred embodiment, the swivel connection is a locking swivel connection. A method of positioning a casing string in the well utilizing the completion tool is also disclosed.
