for obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as x-ray computed tomography, ct, seems to be precise and accurate. porosity is deducted from the ct image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. more than one hundred samples with carbonate litho...

The Upper Jurassic carbonates of the eastern part of the Kopet-Dagh Basin, with thickness of 470 m, are the major gas-bearing reservoir in NE Iran. The objectives of this study are recognition of diagenetic history and estimation of porosity related to dolomitization. Based on field and laboratory study, four carbonate facies associations have been identified at the Mazdavand outcrop. Most of t...

The aesthetic properties of ornamental stones, including colour, texture, and the presence or absence discontinuities, are influential in their use marketing. This is particularly critical brecciated rocks such as Marrón Emperador (ME) stone, a dark brown breccia dolostone (Upper Cretaceous, southeast Spain). ME shows high chromatic textural variability, which one its most appreciated commercia...

The characterisation of both surface and subsurface pathologies (position, depth, width, …) that affects the porous materials used in building constructions, once service, is important to establish most suitable intervention strategy. In this sense, use non-destructive techniques allows analysis different properties without affecting material. present study shows accuracy situ techniques, such ...

The south-eastern Gorny Altai is one of the most hazardous seismogenic area in north Central Asia. We present a synthesis field, 230Th-U geochronological, mineralogical and geochemical data collected on seven Quaternary travertines. All travertines occur within zones active faults that border Chuya Kurai intermontane basins. Travertine cement mainly comprises calcite (with minor amounts aragoni...

In this paper, the depositional environment, age, and tectonic context of Sub-Himalayan Kuldana Formation are discussed in detail. To determine Formation’s setting, sedimentological, palaeontological, petrographic investigations have been conducted accordingly. The lithologically consists both siliciclastic carbonate rocks. Petrographically, sandstone is divided into litharenite feldspathic pet...

As the heterogeneity of pore systems, carbonate rocks commonly exhibit unpredictable porosity vs. permeability relationship and make exploitation prediction prolific reservoirs difficult. Most published studies on systems were conducted in sandstones shales, while rocks, especially dolostones have received little attention. In this study, we investigate porous dolostone reservoir Lower Triassic...
