This capability is crucial for reservoir characterization, allowing engineers to infer properties such as permeability, porosity, and fluid saturation levels across different layers. The improved resolution in data interpretation directly translates to more effective...

... of capillary pressure results in ~77% overestimation of reservoir permeability. Similarly, for a simulated DFIT case, this contribution is up to 26.5%, leading to ~77% overestimation of reservoir permeability. A sensitivity analysis performed herein underscores the significance of considering interfacial...
