... In our earlier research, porosity-permeability relationships were resolved by additional information about the pore system, which was mainly related to the rock texture and diagenesis ( Dernaika and Sinclair, 2017 and Dernaika et al., 2019 ). The research was focused on seven different...

..., grain size and sorting, porosity, and permeability. Due to the sensitive nature of this study, it can only be performed in a collaboration of two parties, wherein each one is executing its respective part independently, and data verification happens only after both digital and physical test data...

.... After generating T 2 distributions for each of the two conditions, a cumulative porosity graph is constructed. This is performed by taking the integral of incremental porosity for T 2 values of equal or less than a particular T 2 value. Then, the cut-off T 2 point can be found by drawing...

... with the complex lithology and pore structure, reservoir permeability is varied and is mostly less than 0.02mD. Evaluating and characterizing this complex reservoir to find a better pay zone was the objective of this study. To evaluate the lithologies, pore structures, porosities, and permeability in quantities...

... of geosciences; therefore, it is vital to clarify their meaning in this paper. The rock type is a geological formation that can be identified and characterised through the rock properties, namely the porosity and the absolute permeabilities and the rock fluid interaction functions, so-called saturation functions...

... and far detector. Self-compensated sigma and neutron porosity (TPHI) don’t require modeling to be applied and prevent issues related to human error or insufficient knowledge in inputting casing parameters. Sigma is useful to compute clay volume combined with elemental spectroscopy and TPHI is useful...

... on water-rock interaction ( Figures 3 and 4 ). All these are discussed in the next sections. Abstract Porosity and permeability of rocks are crucial parameters utilized to assess the quality of oil and gas reservoirs. Diagenesis in carbonate reservoirs commonly results in dissolution, and creates...

... of petrophysical properties (porosity/permeability) being similar. Moreover, real-time Sw estimation would be required in addition to porosity to minimize the risk of drilling a producer into water bearing intervals. In fact, the comparison between petrophysical parameters is more appropriate to heterogeneous...

... in a good porosity zone. Along the boundary orientation for geosteering purposes, the technology was able to map another two porous zones within a 20 ft depth of the investigation. The qualitative formation resistivity, both Rh and Rv, were also used for formation evaluation in this reservoir at the well...

At the very least, it also depends on porosity, permeability, fluid densities, interfacial tension, and contact angle. Limiting it to height requires adding in all of these other functionalities as afterthoughts rather...
