Abstract
The objective of this study is to utilize numerical simulation of heat conduction at pore scale level in order to provide a better understanding of the effects of phase distribution on the effective thermal conductivity of rocks. The first part involves the analysis of tomography images of sandstone rocks as well as sand packs by employing maximal inscribed balls method. It follows by obtaining two phase fluid distribution at capillary dominant equilibrium condition. Then, a numerical simulation based on steady state heat flow model are applied to rock samples at different saturation for both water wet and oil wet conditions. The second part is concerning the assessment of effective thermal conductivity dependence on heat flow direction for both water saturated and oil saturated rocks at a wide temperature range.
