Abstract
A packer that accommodates a control line or I-wire within its sealing element. The sealing element has a longitudinal groove to accommodate the I-wire or control line such that, when the sealing element is compressed, it closes around the I-wire or control line to envelope it as the sealing element makes peripheral contact with the casing, tubular, or the wellbore. The control line or I-wire does not go through the mandrel or body of the packer, and additional joints used in prior techniques for accommodating control lines or I-wires going around packers is eliminated.
