Deeply buried reservoirs are one of the main options to extend the oil & gas reserves and to keep on satisfying the growing need of energy. In this context, the ability to determine the temperature profile of the mud while drilling is a crucial issue from the design of a well to the control of the rheological properties of the mud.

The present work is a study of the heat transfers occurring between the mud and the formation while circulating in a well. Firstly, a model, based on an empirical Nusselt law, was built and implemented in a numerical software. Secondly, we compared the results found with the numerical software with field data, which was made possible thanks to the collaboration of Total.
