... Abstract Fluid invasion in reservoir formations has great interest for enhanced oil recovery and reservoir drilling operations. While a reduction on water mobility is aimed to improve volumetric sweep efficiency, drilling fluids are formulated to avoid damage on reservoir formation...

... in porous media 1–9 . In underbalanced drilling (UBD), even if the pressure gradient is negative, drilling fluid invasion into reservoir can still occur due to the presence of capillary pressure or temporary overbalanced pressure 10–12 . The economic impact of poor productivity of open hole wells has pushed...

... simulation. Free imbibition in fractured system was also investigated and compared favorably with pore network simulation. This process first involves the rapid invasion of the matrix, followed by the subsequent penetration of the fracture. A simplified theory was also developed for the experiments. All...

Unlike previous studies, this method uses Scanning Electron Microscopy (SEM), which leads to the appraisal of the depth and extent of the core invasion to characterize the kind of filter cake formed.. The impairment mechanism...
