Abstract

A method includes coupling a core of a heating section to a core of an overburden section of an insulated conductor. A diameter of the core of the heating section is less than a diameter of the core of the overburden section. A first insulation layer is placed over the core of the heating section such that at least part of an end portion of the core of the heating section is exposed. A second insulation layer is placed over the core of the overburden section such that the second insulation layer extends over the exposed portion of the core of the heating section. A thickness of the second insulation layer is less than a thickness of the first insulation layer and an outer diameter of the overburden section is substantially the same as an outer diameter of the heating section.

First claim

What is clamed is:

1. A method for coupling a heating section and an overburden section of an insulated conductor heater, comprising:
coupling a core of the heating section to a core of the overburden section, wherein a diameter of the core of the heating section is less than a diameter of the core of the overburden section;
placing a first insulation layer comprising one or more blocks of insulation over the core of the heating section, wherein at least part of an end portion o…
