Discovery and significance of Quaternary aqueously deposited aeolian sandstones in the Sanhu area, Qaidam Basin, China
Qaidam Basin Qigequan Formation Aqueously deposited Aeolian sandstones Paleoclimate
2018/4/2
Influenced by neo-tectonic movement, the Sanhu area of China’s Qaidam Basin formed in the Quaternary in response to migration of its depocentre. A study of core material from the Qijia 1 Well reveals ...
Microscopic characterization and formation mechanisms of deepwater sandy-debris-flow and turbidity-current sandstones in a lacustrine basin: a case study in the Yanchang Formation of the Ordos Basin, China
Sandy debris flow Turbidite Ordos Basin Petrology Reservoir properties
2018/4/2
Deep-water deposition is a current issue in sedimentological research. Sandy-debris-flow sandstones and turbidity-current sandstones are the main types of sandstone that are the focus of considerable ...
Preserved Sm-Nd Isotopic Composition as Useful Provenance Indicators in Neoproterozoic Sandstones in the Voltaian Basin, Ghana
Isotope Model Age Provenance Sandstone Voltaian Basin
2013/3/8
The provenance of sandstones derived from theLower Voltaian Kwahu-Morago Group and the Middle Voltaian Oti-Pendjari Group of the Neoproterozoic Voltaian basin are discriminated by their Sm-Nd Isotopic...
Water Saturation Dependence on CO2 Sorption Potential of Sandstones
CO2 Water Saturation Sorption Potential Sandstones
2013/3/8
For the assessment of the carbon dioxide (CO2) storage potential of water-filled reservoir rocks (i.e., saline aquifers), it should be first important step for a thorough understanding of the effect o...
Geomechanical Characterization of Sandstones Cliffs of Segou (Senegal, West Africa) in the Madina Kouta Basin
Unconfined Compression Test-Uniaxial Compression Strength (UCT, Rc)
2013/3/7
This work presents the behavior of Segou sandstones in the laboratory and in the field conditions. Four types of sandstone are collected in the northern part of the Madina Kouta basin (eastern Senegal...
Diagenetic clay mineral distribution in Mesoproterozoic sandstones of the Cariewerloo Basin, South Australia – implications for uranium mobilisation
Diagenetic clay mineral distribution Mesoproterozoic sandstones the Cariewerloo Basin implications uranium mobilisation
2012/3/30
A thick sequence of largely undeformed red-bed sandstones of Mesoproterozoic age, collectively termed the Pandurra Formation, overlies a wide area of crystalline basement of the central and eastern Ga...
Determination of overpressures in sandstones by fluid-flow modelling:The Haltenbanken area,Norway
overpressures in sandstones fluid-flow modelling Haltenbanken area
2009/12/3
This article is aimed at explaining why sandstone reservoirs in the Haltenbanken area of the Mid-Norwegian shelf frequently exhibit great variations in pore pressure development over short distances. ...
Depositional facies and reservoir quality of deep-marine sandstones in the Norwegian Sea
Depositional facies reservoir quality deep-marine sandstones Norwegian Sea
2009/12/3
During the Late Cretaceous and Early Paleocene, deep-water depositional systems deposited sandstones in the Norwegian Sea. The reservoir quality is variable and difficult to predict because of variati...

Determination of overpressures sandstones fluid flow modelling Haltenbanken area
2009/12/2
In my paper (Nysæther 2006) on the development of overpressures in Haltenbanken, I sought to understand the geological principles that govern the distribution of these pressures. I introduced a ...
Ferroan dolomite cement in Cambrian sandstones:burial history and hydrocarbon generation of the Baltic sedimentary basin
Ferroan dolomite cement Stable isotopes Cambrian sandstones Baltic basin
2009/10/20
The conditions and timing of carbonate cementation in Cambrian sandstones of the Baltic sedimentary basin were determined by oxygen and carbon stable isotope and chemical data in combination with opti...
