Abstract

The trend toward drilling deeper and consequently hotter wells places increasing demands on the electronics in the bottomhole assembly. This article introduces and discusses the benefits and limitations of a new technology to reduce the temperature of circulating fluids in wellbores. This technology makes use of phase-change materials (PCM), which utilize the latent heat of phase change to absorb the energy transferred to the drilling fluid from the formation or the drilling string. A combination of mathematical and physical modeling is used to determine the temperature reduction in drilling fluids that can be achieved with conventional PCMs, and new forms of PCMs are discussed.
