A typical reservoir for CGS is a geological formation consisting of sandstone or carbonate rock characterized by 'good' effective porosity
hydrocarbons effective porosity
The interconnected pore volume or void
An effective porosity
was employed when approximating the fluid flow resistance because not all pores were open and well connected between each other for gas flow.
Influence of the amount of waste on effective porosity
Therefore, the effective porosity
is a quantity that can be used in all reservoir engineering calculates.
During this project, one of the author's responsibilities was to determine the effective porosity
in the aquifers and aquitards.
factor of the directional irregularity of the structure N, capillary speed g of the mass flow rate at the normal conditions, effective porosity
of paddy soils as an estimation of its saturated hydraulic conductivity.
e] is the effective porosity
, the pore volume fraction that contributes most to the flow of water when the soil is saturated, defined as the difference between total porosity and the water content at -33 kPa.
Magnetic susceptibility, saturation isothermal remanent magnetization, natural remanent magnetization, electrical resistivity, dielectric constant, wet P-wave velocity, effective porosity
, and wet, dry and grain densities were measured in the Petrophysical Laboratory of Research Institute of Earth Crust of St.
Calculated results from these modules include: (1) total and effective porosity
independent of mineralogy using NUMAR's C/TP logging data, (2) cation exchange properties from the C/TP clay mineral associated porosity, (3) a total permeability, (4) hydrocarbon volume using NUMAR's patented "porosity differences" method, (5) hydrocarbon volume and type using NUMAR's patented Time Domain Analysis method, (6) a variety of other formation evaluation information through synergy with conventional well logs.
Statoil researchers have successfully generated effective porosity
, absolute permeability and two-phase relative permeability values from SBED for input to large-scale reservoir simulations and reserve estimations.
