Joint Elastic-Electrical Properties of Reservoir Sandstones
… and electrical properties of typical reservoir sandstones for improved insight into wave propagation phenomena in porous rocks. <br/><br/>A high quality joint elastic-electrical dataset has been collected on a set of 67 sandstone samples showing a range of porosities, permeabilities and clay …

Hydraulic fracturing of artificially generated soft sandstones
… of hydraulic fracturing take place in soft sandstones using moderate to low viscosity fluids. Soft sandstones represent the host rock for a large portion of active aquifers and oil and gas reservoirs because their high porosity both enhances storage and facilitates extraction. The …

Thermal and Diagenetic Evolution of Carboniferous Sandstones, Central Appalachian Basin
… and diagenetic evolution of Carboniferous sandstones in the central Appalachian basin has been resolved using various techniques. Paleothermometers including vitrinite reflectance and fluid inclusions indicate that burial of Lower and Upper Pennsylvanian strata of the Appalachian Plateau in …

How does cement influence the mechanical properties of sands and sandstones?
… bands have been studied in poorly cemented sandstones, yet there are questions about how grains can break (rather than slide past one another) in such loose sediments/rocks. The strength and distribution of cement may provide an answer. Detailed 3D observations are required to understand the …

Faults as episodic conduits for hydrocarbons, CO2 and groundwater in sandstones
… two general classes of lithology. In porous sandstones, deformation is accommodated by deformation bands and fractures. In tight limestones and siltstones deformation is accommodated by fracturing and the formation of clay-rich fault rocks. Evidence for multiple fluid flow events can be …

The effects of commercial chemical cleaning processes on sandstones in Scotland.
… of commercial chemical cleaning processes on sandstones in Scotland. The work follows a logical path from an understanding of the materials, both the stones and the chemical cleaners, involved. There is a great variation in sandstone types commonly used in buildings in Scotland, and of the 24 …

Detrital Zircon Analysis of Permian Victoria Group Sandstones, Transantarctic Mountains, Antarctica
The Beacon Supergroup in the central Transantarctic Mountains, the Gondwana sequence of Antarctica, comprises Devonian (inferred) and Permian-Triassic strata. The latter were deposited in an intracratonic basin which evolved into a foreland basin in mid Permian time. Sedimentary petrology and …

Methane potential of upper Fort Union formation sandstones, Campbell County, Wyoming
… in the Powder River Basin for many years. The sandstones associated with these coals have also proven to be gas-charged, but industry has done little with the sandstones thus far. The purpose of this study is to determine the paleoenvironrnent responsible for the deposition of the coal and …

Stratigraphy, sedimentology and petrophysics of transgressive tight gas sandstones, Almond Formation, Wyoming
… become paramount to the development of tight gas sandstones. In this way, a refined understanding of the primary sedimentary, stratigraphic and diagenetic controls on rock quality permits more reliable hydrocarbon distribution prediction and more economical drilling programs. The Almond Formation …

Methane adsorption into sandstones and its role in gas recovery from depleted reservoirs
… the interaction of the mineral components of sandstones (i.e. Quartz, Plagioclase, feldspar and clays), with methane (CH4), the effect of pressure and the interaction between water/brine and methane (CH4) gas in a competitive sorption environment for sandstones and their constituents. The …

Sedimentology of multistorey fluvial sandstones of the Mississippian Cypress Formation, Illinois Basin, USA
… of the basin, the Cypress Formation contains sandstones up to 60 m thick in a northeast-southwest trending belt known as the Western Belt. Thick Western Belt sandstones have potential for nonconventional carbon dioxide enhanced oil recovery (CO2 -EOR) and storage, whereby CO2 injection aims to …
