... characterization of carbonate rock pore structure. The method developed includes that we first calculate the volume fractions of crack pores (microcracks and microfractures with a low aspect ratio α ), reference pores (interparticle pores with a medium α ), and stiff pores (moldic and vuggy pores with an α...

... PNL interpretation approach, as appropriate. In detail, after the selection of fit-for-purpose curves and their physics-based models, a joint inversion is performed to reconcile models and actual measurements to solve for water saturation, reservoir gas and CO 2 fractions in selected cases...

... error between the estimated wettability indices and the fraction of water/hydrocarbon-wet beads is less than 20%. Moreover, we showed that water saturation can be estimated by interpretation of 2D-NMR measurements with average relative errors of less than 10%. The results clearly demonstrate...

... water fraction as an additional model parameter. Thus, the modeled dielectric dispersion is controlled by a few key petrophysical parameters: the water-filled porosity, the brine salinity, the water phase tortuosity exponents, and the trapped water fraction. Within our model construction, the trapped...

.... Effective stress (σ′) is expressed as the difference between total applied stress (σ) and pore pressure multiplied by Biot's coefficient (α). The ‘α’ for highly porous rocks is unity where applied load is counteracted equally by grain-matrix and pore-pressure. However, for tight rocks, only a fraction...
