Sandstones and Sandstone Reservoirs
2010About 50% of all petroleum reservoirs are sandstones; outside the Middle East, carbonate reservoirs are less common and the percentage is even higher. The most important reservoir properties are porosity and permeability, but pore geometry and wetting properties of the mineral surfaces may also influence petroleum production.

PARTICLE TRANSPORT IN SANDSTONES
Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1977Abstract Particle transport within the Berea, Noxie and Cleveland sandstones having mean pore sizes of 10, 15 and 30 microns, respectively, was studied by injection of aqueous suspensions of sand particles having mean particle sizes of 4, 6 and 7 microns.

Itacolumites: The flexible sandstones
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980Summary Itacolumites (flexible sandstones) display a bimodal stress-strain behaviour resulting from an unusual inter-digitated grain-to-grain fabric. The sandstone can move freely over a limited arc, then locks, and displays only elastic behaviour. Grain contacts are all open about 5 μm, thereby permitting some free movement.

Pore-throat sizes in sandstones, tight sandstones, and shales
AAPG Bulletin, 2009Abstract Pore-throat sizes in siliciclastic rocks form a continuum from the submillimeter to the nanometer scale. That continuum is documented in this article using previously published data on the pore and pore-throat sizes of conventional reservoir rocks, tight-gas sandstones, and shales. For measures of central tendency (mean, mode,

On the “Caradoc Sandstone” of Shropshire
Quarterly Journal of the Geological Society of LondonSummary The conclusions to be drawn from the foregoing data may be thus shortly stated. The rocks east of the Longmynd hitherto known as Caradoc sandstone are now divided into two groups. The lowest and greatest portion is equivalent to the middle and upper portions of the Llandeilo and Bala rocks, and were accumulated in the ...

Durability tests on sandstone.
2008The sandstone is widely used as cladding stone, even in historic building. Its decay its commonly associated with the action of salts or with sulphation in polluted conditions. In fact, in many cases, the decreasing of mechanical properties under the action of salt crystallization and SO2 is higher than the one induced by frost and by thermal shock ...
