The formation factor, which reflects the electrical conductivity of porous sediments and rocks,
is widely used in a range of research fields. Consequently, given the discovery of numerous …

Ascending hydrothermal fluid flow and subsequent hypogene karstification can control the
formation of high-permeability zones in folded or faulted carbonate rocks. This study …

Excess permeability in carbonate reservoirs is typically related to the presence of dual-
porosity multiscale nonmatrix features that can result in early water production or …

Fault-karst systems in deep and ultra-deep carbonate reservoirs have a huge potential for
hydrocarbon exploration. However the characteristics of reservoir space and the main …

Superposed events of rock exposure, fracturing, and the hydrological dynamics, are key
elements that influence epigenic karstification in carbonate reservoirs. However, they are not …

Caves developed in carbonate units have a significant role in fluid flow, but most of these
subsurface voids are below seismic resolution. We concentrated our study on four caves to …

Carbonate reservoirs are often affected by fractures and karst that increase rock's
permeability. An accurate characterization of reservoir architecture, fracture attributes and …

Karst processes may be critical for develo** secondary porosity and permeability within
carbonate reservoirs and aquifers. Karstification can significantly influence reservoir storage …

This study shows how mechanical stratigraphy influences deformation bands' structural
attributes in faulted, heterolithic arkosic sandstones in the Rio do Peixe Basin, northeastern …

Understanding the karstification process in fractured carbonates is a key factor in develo**
and exploiting fractured and karstified reservoirs. This study documents the relationship …
