ABSTRACT:
An apparatus and method for protecting temperature sensitive components from the extreme temperatures a hydrocarbon producing wellbore. The apparatus comprises an inner housing encompassed by an exterior housing, where a plenum is formed between the two housings. A vacuum is formed within the plenum. The temperature sensitive components are stored within the inner housing. An aerogel composition is placed on the outer surface of the inner housing thereby providing added insulation for protecting the temperature sensitive component. Optionally the aerogel composition can be added to the inner surface of the outer housing. Yet further optionally, a reflective foil may be disposed over the aerogel composition of the inner housing.
