Experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles [PDF]

open access: yes, 2015
Fractured rocks are known to exhibit seismic anisotropy and shear wave splitting (SWS). SWS is commonly used for fractured rock characterization and has been shown to be sensitive to fluid type. The presence of partial liquid/gas saturation is also known

INTEGRATION OF MULTIPLE LOG DATA FOR ACCURATE POROSITY AND PERMEABILITY ESTIMATION, NIGER DELTA BASIN [PDF]

open access: yesGeological Behavior
The use of well logs is significant to obtain accurate and improved porosity, permeability and watersaturation. This accounts for the ability of the wells to store and transmit fluid (hydrocarbon) and itsavailability potential. Three wells (OB-14, OB-15,

Porosity and Water Saturation Estimation for Shale Reservoirs: An Example from Goldwyer Formation Shale, Canning Basin, Western Australia

open access: yesEnergies, 2020
Porosity and water saturation are the most critical and fundamental parameters for accurate estimation of gas content in the shale reservoirs. However, their determination is very challenging due to the direct influence of kerogen and clay content on the

Effect of Water Saturation on Radiative Transfer

open access: yesVadose Zone Journal, 2005
Porous media such as tissues, soil materials, porous rocks, and concrete become darker with increasing water content. Most methods used to quantify this behavior are based on statistical models. Physical models have rarely been used for this purpose.

Chute-Assisted Oxygen Saturation of Water

open access: yesPower Technology and Engineering, 2002
Saturation of water with oxygen is an important technological step in improving water, quality. In practice, this is achieved by forced aeration using special technical facilities - aerators. The conventional pneumatic, mechanical, and physicochemical methods of aeration require energy for their realization; many aerators are complex in design and need
