Abstract
A cable pack-off apparatus for a wellbore is provided. The apparatus is designed to threadedly connect to the auxiliary port of a tubing head, over the wellbore, and to receive a power cable. The power cable provides power to an ESP downhole. The cable pack-off apparatus provides a self-sealing mechanism in the event that the power cable must be pulled (or becomes pulled) from the wellbore, such as in the event of parted tubing. A packing element sealingly receives the power cable within a housing of the apparatus. A method for self-sealing a tubing head over a wellbore is also provided herein.
