Influencia del bitumen sobre la calidad de un reservorio siliciclástico: aplicación al campo de Salam en el desierto occidental de Egipto
Bitumen are rarely taken into account in the petrophysical characterization of reservoirs because they may be rather difficult to distinguish. This paper focuses on the effects of bitumen on the reservoir quality of the sandstones from the Salam Field in the Western Desert (Egypt). We describe the v...

| Resumo: | Bitumen are rarely taken into account in the petrophysical characterization of reservoirs because they may be rather difficult to distinguish. This paper focuses on the effects of bitumen on the reservoir quality of the sandstones from the Salam Field in the Western Desert (Egypt). We describe the various morphologies of the bitumen by SEM and we relate these data with the chemical composition of the bitumen and with the porosity determined by Hg injection. The coatings of bitumen affect preferentially the reservoir quality restricting pore throats, whereas the pore fillings of bitumen affect mainly the macroporosity. |
