DESCRIPTION:<h2>Thermal segregation in petroleum reservoirs</h2>\n<p>&nbsp;</p>\n<p>\n<strong>Abstract<br />\n</strong>In many petroleum reservoirs, the fluid properties are not the same through the reservoir thickness.</p>\n<p>The variation of composition, i.e. compositional grading, can affect reserve estimation, production and EOR strategies.</p>\n<p>One simple reason for compositional grading is the gravity force; heavy components tend to be in the lower part of the fluid column, and the light components are found in the upper part of the reservoir. </p>\n<p>However, this is not the only reason, because there are other forces that can have an effect on the compositional grading such as thermal diffusion due to temperature gradient.</p>\n<p>In order to determine the variations in pressure and composition with depth and to be able to indicate if/where a gas-oil contact exists, we have built a model based on the irreversible thermodynamics principles.</p>\n<p>The model is based on the approach to thermodiffusion in porous media developed by Montel et al. [1] Using the relationships where pressure, chemical potential, and thermal gradient are linked, the distribution of chemical components in the petroleum reservoir is described.</p>\n<p>Finally, we validate our model and calculation procedure for the compositional grading by comparing with some case studies in the literature.</p>\n<p class="p2">&nbsp;</p>\n<p class="p2">[1] F.
