Tight sandstone reservoirs basically have low porosity and permeability, a complex pore
structure and a heterogeneous distribution of immiscible fluids. With the development of …

Abstract Evaluation of tight gas sandstone (TGS) reservoirs and estimation of their reserves
are associated with significant uncertainties. Indeed, estimation of electrical properties, such …

Many studies have worked on the estimation of fluid saturation as an important petrophysical
property in hydrocarbon reservoirs. Based on Archie's law, proper determination of …

Despite the significant progress made in tight gas exploration and development in recent
years, the understanding of the dynamic mechanisms of tight gas accumulation is still …

As a key parameter in the calculation of fluid saturation, cementation factor (m) is routinely
approximated using the Archie's equation. Numerous correlations and several techniques …

Rock typing with its various applications reduces the required time and cost for petrophysical
analysis by categorizing similar rocks into distinct groups. Rock typing is divided into …

Rock typing techniques have relied on either electrical or hydraulic properties. The study
introduces a novel approach for reservoir rock typing, the hydraulic-electric index (HEI) …

Accurate determination of cementation factor (m) has a significant role in the petrophysical
characterization of underground reservoirs. For clean sandstones, the application of this …

Maar‐diatreme volcanoes are small volcanic structures with a funnel‐shaped crater
surrounded by a tephra‐ring. They are usually formed by the explosive phreatomagmatic …
