The technique also witnessed a shift from being a purely geophysical interpretation tool to a reservoir management tool, which can be used to assess the remaining hydrocarbon volumes and optimize the recovery strategy through quantitative estimates of changes in reservoir properties such as fluid saturation
and pressure, according to CGGVeritas.
in subsurface media, substantially influence the characteristics of seismic waves during its propagation through deformable saturated porous media.
Probe, a leading supplier of logging and reservoir monitoring technology to the global oil and gas and geothermal industries, has announced the launch of RAS pulsed-neutron tool, a three-detector system that uses sigma and carbon-oxygen (C/O) techniques to measure reservoir fluid saturation
of oil, water and gas.
Under the clarified condition, nuclear magnetic resonance (NMR) leads to a feasible analysis of fluid saturation
, which could be linked to the pore-throat structures that are tested by RMICP.
It increases with the degree of fluid saturation
and pressure, while decreases with the increase of porosity and temperature.
What is more, the water/oil relative permeability curves were correlated with the capillary number and fluid saturation
. Relative oil and water permeabilities can be correlated with IFT through the capillary number.
(8) The initial fluid saturation
is uniform at the irreducible water saturation.
The moduli and density effects generate velocity variations which depend on the rock properties such as porosity, fluid saturation
, and texture.
The Petrophysics training focused on fluid saturation
measurements from boreholes in oil and gas reservoirs.
It is already known that the relatively permeability [k.sub.n] is function of displacing fluid saturation
[S.sub.i], for definiteness of the mathematical analysis, we assume the following standard relations for analytical relation between relative permeability-phase saturation and capillary pressure-phase saturation as, Scheidegger and Johson
