An understanding of the physical mechanisms by which non-wetting fluids become entrapped is important to oil recovery techniques from reservoir rocks, and the structural characterization of porous media. The mechanisms of entrapment and the spatial distribution of non-wetting fluid (mercury) within model materials with similar chemical and geometrical properties to oil reservoir rocks have been investigated using mercury porosimetry and computed X-ray tomography. The combination of both techniques has allowed the direct observation of entrapped mercury within the model materials. In this thesis, a novel experimental technique involving combined mercury porosimetry and mercury thermoporosimetry techniques has been used to determine pore size distributions for disordered porous solids. Mercury porosimetry was conducted, and the mercury entrapped following porosimetry was used as the probe fluid for thermoporosimetry. The fully integrated combination of techniques described here permit...

A Simple Method for Evaluating Pore Surface Mineralogy1993 •
SPE Members Majority of mineralogical studies directed at hydrocarbon producing formations are conventional studies that treat the formation as a bulk entity. Focusing on pore surface mineralogy, which is the identification of the elemental composition of the pore surface, seems to be a more realistic approach, since fluids in the formation come into direct contact with these elements on the surface. Rock-fluid properties such as relative permeability, wettability, capillary pressure and certain rock properties, are influenced by pore surface mineralogy. Hence, characterization of pore surface mineralogy will enhance understanding of the interaction between fluid and the porous medium. This paper discusses Multiple Voltage Scanning Electron Microscopy as a novel method for characterization of pore surface mineralogy. Multiple Voltage Scanning Electron Microscopy, a new method that has successfully been used to study the surface of particles, has been implemented to identify the elem...

Characterisation of pore structure by combining mercury porosimetry and micrography2001 •
Savonnières, a French layered oolithic limestone, shows important ink-bottle effects. As a consequence, a great discrepancy is observed between the results of different techniques to determine the pore volume distribution. It is shown that mercury intrusion porosimetry results can be considered as the main drainage curve and are, for this kind of materials, not convenient to determine the apparent pore volume distribution due to hysteresis phenomena. The main wetting curve is obtained using image analysing techniques on SEM-micrographs, combined with pressure membrane apparatus results on capillary saturated samples. A simple structural hysteresis model is developed to predict the mercury intrusion porosimetry results, starting from the main wetting curve. The good agreement between theory and experiment verifies that the large difference between main wetting and main drainage curve can indeed be attributed to structural hysteresis. In this way, the presented technique gives, in addition to a better knowledge of the pore volume distribution, insight in the pore geometry and connectivity, which can serve as input for microstructure-based transport models. La courbe de rétention d'eau et la courbe de distribution volumique des pores obtenues au moyen de la porosimétrie à intrusion de mercure (PIM), de l'appareil à membrane de pression et des techniques d'analyse d'images sur micrographe-MEB sont comparées pour la pierre de Savonnières, une roche calcaire oolithique plus ou moins stratifiée en provenance de la France. Le matériau montre d'importants effets «bouteille d'encre». Il est démontré que les résultats obtenus par PIM peuvent être considérés comme courbe principale de drainage et ne peuvent pas être utilisés, pour ces matériaux, pour déterminer la distribution volumique apparente des pores en raison de phénomènes d'hystérésis. La courbe principale de mouillage est obtenue par des techniques d'analyse d'images sur micrographe MEB, combinées avec les résultats de l'appareil à membrane de pression sur des échantillons saturés par capillarité. Un modèle structurel simple d'hystérésis est développé; il est capable de prédire les résultats obtenus par porosimétrie à intrusion de mercure au départ de la courbe principale de mouillage. Ceci permet de vérifier que la grande différence entre les courbes principales de mouillage et de drainage peut en effet être attribuée aux hystérésis de structure. Comme conséquence, la méthode présentée donne, outre une meilleure connaissance de la distribution volumique des pores, un aperçu de la géométrie des pores et de la connectivité, ce qui peut servir de données en entrée pour des modèles de transfert basés sur la microstructure.
