Clay minerals are considered the most important components of clastic reservoir rock evaluation studies. The Shurijeh gas reservoir Formation, represented by shaly sandstones of the Late Jurassic-Early Cretaceous age, is the main reservoir rock in the Eastern Kopet-Dagh sedimentary Basin, NE Iran. In this study, X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopic (S...

The micropore structure’s permeability contribution to total of the heterogeneous reservoir with multiscale pore structures is critical for evaluation but still not well understood. This paper proposes a structure characterization method based on high-resolution SEM images quantitatively analyse structures’ content and their contributions via six steps. First, image-based rock typing implemente...

Abstract The present work describes and evaluates the reservoir quality of sandstone Nubia Formation at Gebel Abu Hasswa outcrop in southwest Sinai, Egypt. Hydraulic flow unit (HFU) electrical (EFU) concepts are implied to achieve this purpose. Paleozoic section made up four formations has been studied. oldest is Araba followed by Naqus (Nubia C D) overlay Durba, Ahemir Qiseib B), where Lower C...

This paper evaluated the oil and gas potential of Cretaceous Yageliemu clastic reservoir within Yakela condensed field lying in Kuqa Depression, Tarim Basin, China. The petrophysical properties interest zones area were characterized using geophysical logs from five wells. results reveal that gas-bearing are by high resistivity, good permeability (K) effective porosity (?eff), low water saturati...

conclusions high hvr diversity among the studied mrsa isolates could be a result of insufficient or inadequate infection-control protocols in tabriz hospitals. moreover, the high number of hvr genotypes showed that hvr typing can be used along with other typing methods in epidemiological studies of mrsa as a useful tool for monitoring, tracking contaminations, and controlling infections in hosp...

in this research a molecular method based on polymerase chain reaction for typing of clostridium perfringens was developed and toxin genotypes of 64 isolates from sheep and goats in iran were determined. the pcr assays were developed for detection of alpha (cpa), beta (cpb) and epsilon (etx) toxin genes, allowing classification of the isolates into genotypes a b, c and d. the field isolates ...

Abstract. Keyboard-typing tracking offers a convenient behavioral data collection method in web-based study settings. This paper investigated the feasibility of utilizing keyboard-typing for stress measurement. We present from two experiments: laboratory with N = 53 participants and an online 924 participants. In both studies, typed standardized text sequences during high-stress or low-stress c...
