The prediction of permeability in heterogeneous carbonates from well-log data represents a
difficult and complex problem. Generally, a simple correlation between permeability and …

There are several methods to estimate permeability from pore throat sizes and NMR T2
relaxation time. Although most of the methods are well-established and work well for …

Appropriate estimation of permeability is considered as one of the significant concerns of
petroleum industries. Due to the growing demand for hydrocarbon fossil fuels in numerous …

This study presents a new way to model high secondary porosity, mainly vuggy porosity, in
naturally fractured reservoirs. New solutions are presented for two cases, one in which there …

In this study, using a relatively large and complete data set of a complex carbonate reservoir,
it is proven that among the numerous methods proposed for the prediction of permeability …

The accurate permeability mapping, even with the aid of modern borehole geophysics
methods, is still a big challenge on the reservoir management framework. One concern …

We report the results of case studies of NMR petro-physics applications in carbonate wells in
the Middle East. In the cases studied NMR was utilized successfully both to compute …

An extensive petrophysical analysis has been carried out on a study well in a giant
carbonate field in the Lower Cretaceous of Abu Dhabi. The well was cored, and a …

Conventional reservoir analysis has always been an extensive process. In order to properly
characterize a reservoir, cores and/or logs have to be obtained. Both core and log analysis …

Sandstone rocks can contain microscopic variations in composition that complicate
interpretation of nuclear magnetic resonance (NMR) relaxation time measurements. In this …
