Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...

The diagenetic history of Triassic sandstone from the Beacon Supergroup, Victoria Land, Antarctica, can be divided into three main phases of shallow burial diagenesis, contact diagenesis (temperatures of 200-300oC), and post-contact diagenesis, on the basis of petrographic and geochemical analyses. Shallow burial diagenesis is characterised by minor compaction, K-feldspar alteration to illite, ...

Numerical micropermeametry is performed on three dimensional porous samples having a linear size of approximately 3 mm and a resolution of 7.5 μm. One of the samples is a microtomographic image of Fontainebleau sandstone. Two of the samples are stochastic reconstructions with the same porosity, specific surface area, and two-point correlation function as the Fontainebleau sample. The fourth sam...

Bruce Railsback, The University of Georgia, Athens, USA. The early search for oil and gas reservoirs centered on acquiring an overall view of regional tectonics, followed by a more detailed appraisal of local structure and stratigra...

a study of the diagenetic evolution of sandstones from panyu low-uplift in the pearl river mouth basin was carried out to unravel the controls on shelf margin sandstone reservoir quality. the reservoir rocks, oligocene volcanic clastic sandstones of the zhuhai formation, have a burial depth of 2765 to 3440 m. 70 samples were studied using the granulometric analyses, x-ray diffraction (xrd) anal...

Great progress has been made in the exploration of tight sandstone gas resources Kuqa depression. Dibei structural belt, which proves previously unproven favorable area for gas. The physical properties, controlling factors, and characteristics from Ahe (J1a) Formation reservoir are analyzed. results show that J1a is mainly feldspar lithic sandstone, with low porosity (average 9.1%) permeability...

The sandstone reservoirs of the He8 member within Lower Permian Shihezi Formation are important targets for oil and gas exploration in southern Ningwu Basin. This study utilized thin-section identification, scanning electron microscopy, X-ray diffraction analysis to examine petrological features reservoir characteristics, evaluate impact mineral composition diagenesis type on porosity reservoir...
