Résumé

A methodology of locating fluid-flow zones in a rock formation is applied to the Buntsandstein sandstone reservoir of borehole EPS1, Soultz-sous-Forêts, France. The method is based on analysing thermal gradients determined by two different methods for a same cored borehole, (1) from temperature log and (2) from thermal conductivity measures. Comparing the two thermal-gradient datasets reveals the fluid-circulation zones in the borehole. Using this approach, we identified three main hot-fluid circulation zones within the Buntsandstein sandstone, two controlled by sedimentary facies and one controlled by tectonic structures.
