Understanding the controls on the elastic properties of reservoir rocks is crucial for exploration and successful production from hydrocarbon reservoirs. We studied the static and dynamic elastic properties of shale gas reservoir rocks from Barnett, Haynesville, Eagle Ford, and Fort St. John shales through laboratory experiments. The elastic properties of these rocks vary significantly between ...

The issues of environmental safety oil-bearing regions are highlighted. Oil and strata waters contain, along with chemical elements, radionuclides, removal which oil to the Earth's surface occurs during gas production. radioactivity rocks aluminosilicate type was investigated. It has been determined that clay from Apsheron region is several times higher than other deposits our republic. noted s...

Mature fault cores are comprised of extremely fine, low permeability, clay-bearing gouges. Saturated granular materials known to dilate in response increases sliding velocity, resulting significant pore pressure drops that can suppress instability. Up now, dilatancy has been measured predominantly clay-poor Clay minerals have frictional strengths and, previous experiments, even small proportion...

Mineral assemblages, reaction textures and mineral composition of the metapelitic rocks from the Mahneshan area in NW Iran are studied to reconstruct the reaction history of the rocks. The phase relation on the real mineral chemistry AFM, AFMn compatibility diagrams and mineral isograds in chloritoid-free and chloritoid-bearing metapelites of Mahneshan Complex were studied in order to determine...

Mechanical behaviour of old masonry may differ from the theoretical one to a great extent, hence it needs to be properly evaluated for quantifying the safety and serviceability of real structures, in view of their rehabilitation and/or seismic reliability assessment. Among the factors affecting such behaviour, the presence of moisture, mainly from rising damp, plays a key role in the deteriorat...

koenenite=[mg7ai4(oh)22]4+.[na4(ca,mg)2ci12]4- , is a typical non-silicate clay mineral of oceanic salt deposits which also widely occurs in salt clay, anhydrite, halite, and potash-bearing rocks. koenenite is found as an undesirable sludge-forming component in the processing of potassium salts . koenenite was first reported, in 1902, as an impurity in a fairly pure halite from the justus! pota...

Several countries, including Canada, contain sizeable bitumen resources in highly fractured carbonate rocks. Any possible recovery of bitumen from these reservoirs will be highly dependent on proper understanding of the rock and fluid properties and how they vary in the reservoir. These carbonates are extremely heterogeneous, and as a result proper reservoir characterization is challenging. In ...

Groundwater in the Triassic Sherwood Sandstone aquifer, Liverpool, UK, has locally elevated chloride concentrations (∼4000mg/l) in parts of the coastal region although there is freshwater right up to the coast line in other areas. The aquifer is cut my numerous faults with vertical displacements of as much 300m. SPOT satellite data 5 have been used for the Merseyside area of Liverpool. The sate...
