US Patent 7431082 Retaining lines in bypass groove on downhole equipment

One or more control lines or other types of lines can be run past a downhole tool such as a side pocket mandrel, for example, in a longitudinal groove with a retaining feature for the control line where the assembly leaves little to stick out and get damaged on run in or on pulling out of the hole. In the preferred version, the groove is a dovetail and at least one retainer can be slipped into the dovetail. Lateral bores into the dovetail allow pins to be driven into a wedge shaped retainer to force it against the control line or lines such that the shape of the dovetail and the shape of the wedge retainer trap the control line within the dovetail. Upon assembly, nothing sticks out from the dovetail or the downhole tool.
