ABSTRACT:
In a well logging system that is subjected to high temperatures and pressures, an improved thermos flask pressure housing is used to insulate sensitive electronic circuits to the detrimental effects of high temperature and extreme pressure. An evacuated area between an inner shell and an outer shell acts as insulation between electronic circuits within such inner shell and the borehole environment surrounding such outer shell.
