Abstract
A method for making a coiled insulated conductor heater to heat a subsurface formation includes pushing the insulated conductor heater longitudinally inside a flexible conduit using pressure. One or more cups are coupled to the outside of the insulated conductor heater. The cups maintain at least some pressure inside at least a portion of the flexible conduit as the insulated conductor heater is pushed inside the flexible conduit. The flexible conduit and the insulated conductor heater are coiled onto a coiled tubing rig.
