ABSTRACT:
An apparatus and method for protecting downhole electronic components and for monitoring the deterioration of such components. The electronic components are positioned within a tool recess, and a vacuum is drawn on the recess to remove oxygen, water vapor, and other contaminants from contact with the electronic components. In one embodiment of the invention, insulating fluid or an inert gas can be placed in the recess to isolate the electronic components. The seal integrity of the recess can be tested before the tool is run into the well or before the tool is set in the well. A pressure sensor monitors the deterioration of the vacuum, or fluctuations in the pressure of the insulating fluid or inert gas, to detect leakage of well fluids into the recess, leakage of gas away from the recess, or to detect gases formed from corrosion of the electronic components.
