Wellbore Stability: Beyond Mud Weight
In this study we demonstrate that relying solely on mud weight (MW) for borehole stability is inadequate. The water phase salinity (WPS), often not considered, plays a crucial role. Inappropriate salinity levels caused instability despite sufficient MW, whereas the correct combination of MW and WPS maintained stability. A geomechanical model that includes chemical effects, even without direct shale samples, accurately predicted the optimal MW and WPS combinations, enhancing drilling efficiency.
Extreme Permeability in Carbonates
Development of carbonate reservoirs with natural fractures or karst comes with unique challenges due to the extreme permeabilities introduced by such features. Traditional reservoir characterization and permeability predictions often get challenged as soon as dynamic data becomes available. Here we will demonstrate how early dynamic data integration can help reduce uncertainty and refine geologic concepts in fractured reservoirs.

La reducción de presión e inyecciones en yacimientos generan deformaciones que pueden causar compactación, subsidencia y cambios en el estado de esfuerzos, afectando la integridad de pozos y provocando sismicidad inducida. Esta presentación muestra cómo modelos geomecánicos 3D usando el Método de Elementos Finitos ayudan a mitigar estos riesgos y optimizar la seguridad y eficiencia en producción.
