Shehata AM, Nasr-El-Din HA (2017) The role of sandstone mineralogy and rock quality in the performance of low-salinity waterflooding.Nov 28, 2022 · Sandstone is a clastic sedimentary rock. It is the most common sedimentary rock found in sedimentary basins worldwide. Sandstone is sand cemented together into a rock. A sandstone rock can be simply identified by simply looking at it. However, a closer examination reveals an interesting mix-up of sediment, cement, and matrix.

For comparison, I have added R.L. Folk’s 1966 classification of terrigenous sandstones (from Folk, 1968, Petrology of Sedimentary Rocks ). In this scheme, sand-dominated rocks and sediments carrying less than 15% matrix are called arenites; those with 15-75% matrix are wackes, and >75% matrix, mudstones. Note that the percentage matrix is ...Berea Sandstone, also known as Berea Grit, is a sandstone formation in the U.S. states of Michigan, Ohio, Pennsylvania, West Virginia, and Kentucky.

These fine-grained tight sandstone reservoirs face enormous challenges due to their extremely low matrix porosity and permeability. Hence, in this regard, the study was carried out to collect the high-quality data on petrophysical properties along with mineralogy …

The most common cements in terrigenous sandstones are quartz, calcite, and clays. Cements may consist of a single mineral or succession of minerals (a kind of cement stratigraphy), depending on the chemical composition and temperature of the fluid that occupies the pores (i.e. interstitial fluid). Fluid flow from pore to pore is also critical ...This research is aimed toward an understanding of the effects of the chemical characteristics and mineral compositions of sandstone and formation water ...

The …In addition, X-ray powder diffraction analysis of clay minerals in white sandstone revealed that the content of kaolinite is high, accounting for 70–80% in weight. It seems then that the abundance of kaolinite is the main cause of the color of the white sandstone facies in the Ordos Basin.

Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism. Metamorphism recrystallizes the sand grains and the silica cement that binds them together.

Diagenetic alteration of sandstone mineralogy: Life and death of provenance information. An important constraint on any diagenetic model is the assumptions made about the original mineral composition of sandstones. When we have petrographic samples to study, we tend to use these samples to help set this constraint.

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks.
