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.

Abstract: A tubing hanger system for suspending a tubing string within a wellbore is provided. The system is designed to place the tubing string in tension. The tubing hanger system comprises a tubing hanger and a tubing anchor. Both the tubing hanger and the tubing anchor are designed to reside in series with the production tubing. The tubing hanger is threadedly connected to the tubing string at the top of the wellbore. The tubing anchor is also threadedly connected to the tubing string but is configured to be set within a string of casing downhole. Beneficially, the tubing hanger and the tubing anchor is each uniquely configured to be set through a rotation of the tubing string that is less than one full rotation. This enables use of a stainless steel chemical injection line extending from the tubing hanger to the tubing anchor. A method for hanging a string of production tubing in a wellbore, in tension, is also provided herein.
