The new downhole insulator for the preheating electrode apparatus used during oil recovery from a subsurface oil-sand formation by in situ Previous HitelectricalNext Hit heating of oil reservoirs has been developed. This insulator consists of a pipe insulated with polyetheretherketone-glass composites and the two-end Hishilex® insulated coupling. The insulator has good Previous HitelectricalTop, mechanical, and thermal properties and high-level watertight seal of resistance to hot water at 290°C.
