Abstract

Current downhole tools, particularly the sensor gauges, are enclosed in a metallic housing that has a circular cross section. This geometry, along with the material properties, specifically the surface properties, of the housing reflect back most of the radiated heat from the electronics concentrating at the center increasing the operating temperature. A simple modification to the design could reduce this internal temperature, thus increasing the life of the tool.
