Abstract
Examples of the present disclosure relate to systems and methods for an encapsulated heating cable within a wellbore. Embodiments may have the durability required for the hazardous and harsh environment of a wellbore, and to provide sufficient heat within the production string to reduce and/or eliminate deposits.
Claims20
A system for heating a wellbore, the system comprising:
- a production string with a first inner diameter;
- a heating cable positioned within the production string, wherein the heating cable is manipulated to contact the first inner diameter of the production string, the heating cable being coiled under pressure, wherein the heating cable is configured to provide sufficient heat within the production string to reduce deposits within the production string during production;
- a tubing stop being a lip positioned on the first inner diameter of the production string, the tubing stop being configured to receive a distal end of the heating cable to restrict a downward movement of the heating cable, wherein the heating cable is configured to be coiled under pressure responsive to positioning the distal end of the heating cable on the tubing stop;
- a capillary string configured to encompass the heating cable, wherein the capillary string is filled with dielectric fluid.

A method for heating a wellbore, the method comprising:
- positioning a production string with a first inner diameter within a wellbore;
- manipulating a heating cable within the production string to contact the first inner diameter of the production string;
- positioning a distal end of the heating coil on a tubing stop, the tubing stop being a lip being positioned on the first inner diameter of the production string, the tubing stop restrict a downward movement of the heating cable;
- coiling the heating cable under pressure;
- creating, via the heating cable, sufficient heat within the production string to reduce deposits within the production string during production;
- encompassing the heating cable in a capillary string, wherein the capillary string is filled with dielectric fluid.
