Abstract
A technique facilitates the logging of hot, subterranean environments with a variety of logging tools. Logging tools with temperature limit ratings may be employed in environments that would otherwise be detrimental to operation of the logging tool due to the heat. The logging tool may be protected through placement of the tool at a desired location within a non-metallic flask. The logging tool also is surrounded with an insulating material and/or a material with a high heat of fusion disposed within the non-metallic flask to increase the time span for operating the logging tool in the hot, subterranean environment.
