Abstract
A downhole protection apparatus, for use in protecting downhole control lines, comprises a sheath defining a channel configured to receive a control line. The sheath is configured to be attached to a tubing. In wellbore applications, the control lines associated with a tubing are inserted into the sheath such that the body of the sheath at least partially encompasses the control line and shields the control line from harsh downhole conditions which may include abrasive action from sand, proppants, wellbore cuttings and other debris. Therefore, the apparatus is configured such that after insertion of a control line into the channel, a body of the sheath protects the control line from an outside environment.
