Tom Hughes


Investigation of oil and gas fields using vertical seismic profiling subjects the equipment used to extreme temperatures and pressures. As wells become deeper and
higher temperature, the need for effective thermal management in instrumentation and the demands placed on the downhole tool system increases. One approach to reduce the temperature of sensitive electronics is to use a thermoelectric cooler to reduce the temperature of the electronics within the tools. This work uses computational uid dynamics to model the temperature profile in a downhole tool when fitted with a commercially available thermoelectric cooling
module and a custom made module. High temperature properties of the module are estimated from simple laboratory experiments and applied to the computational
model to map the temperature field of the system. The simulation data is compared to experimental hot oil bath testing data and found to be in close agreement.
