Annotation

The upper Triassic sandstone reservoir is one of the most important oil and gas reservoirs at the east of Syria, it contains about 60 % of the total hydrocarbon volume at the area. The sandstones from this reservoir were characterised for their mineralogical and chemical properties. The experimental methods; optical microscope, scanning electron microprobe SEM, X-ray diffraction analysis (XRD), X-ray fluorescence analysis (XRF), and diffraction system analysis (EDS) have been compared for this reservoir. The study showed the upper Triassic sandstones are typically of quartz arenite, detrital quartz is the dominant phase (mean 74%) with an argillaceous matrix and some carbonate cement, with a small proportion of amorphous material. Quartz overgrowth is one of the most important authigenic minerals within upper Triassic sandstones, it presents in all the samples and occupies between traces to 9%, and form a syntaxial overgrowth the detrital grains and cement between the grains. The representative XRD shown that the quartz is the main mineral present in all the studied samples and content from 55 to 85%. The content of other non-clay minerals includes K-feldspar, plagioclase, dolomite, siderite, anhydrite, barite, pyrite, halite and mica. XRF analysis identified chemical elements within the different types of the upper Triassic sandstones such as: aluminium (Al), silicon (Si), titanium (Ti), iron (Fe), manganese (Mn), magnesium (Mg), calcium (Ca), sodium (Na), potassium (K) and phosphorus (P). The proportion of SiO2 and Al2O3 results are slightly higher for most samples, this reflect silica based and clay content for these sandstones.
