Dual-domain models are used to explain anomalous solute transport behavior observed in diverse hydrologic settings and applications, from groundwater remediation to hyporheic exchange. To constrain such models, new methods are needed with sensitivity to both immobile and mobile domains. Recent experiments indicate that dual-domain transport of ionic tracers has an observable geoelectrical signa...

At the Centre for X-ray Tomography of the Ghent University (Belgium) (www.ugct.ugent.be) besides hardware development for high-resolution X-ray CT scanners, a lot of progress is being made in the field of 3D analysis of the scanned samples. Morpho+ is a flexible 3D analysis software which provides the necessary petrophysical parameters of the scanned samples in 3D. Although Morpho+ was original...

Shale reservoirs, the most important unconventional resource, are difficult to characterize. formations require detailed interpretation of geological, petrophysical, and geochemical analyses, an integration these disciplines. In terms geological interpretation, commonly used sequence stratigraphy analysis includes a lithofacies analysis. The application shales facilitates ability relate between...

different methods exist for the zonation of oil reservoirs based on petrophysical data and well logs. among them are: permeability-porosity cross polt, pickett and soder and gill methods. in this study a statistical zonation technique has been used for the marun and pazanan oil reservoirs in iran based on effective porosity, density, sonic, neutron and resistivity data. petrophysical interpreta...

Geomechanical characterization plays a key role in optimizing the stimulation treatment of tight reservoir formations. Petrophysical models help classify rock as conventional or unconventional type and determine hydrocarbon-saturated zones. petrophysical are fundamentally based on well-log data that provide reliable high-resolution information, used to various relationships between measured bor...
