Multi attribute transform and Probabilistic neural network in effective porosity
In the interval 323 - 1323 m, section of 12'', gaseous hydrocarbons were found from 359 m to 595 m, with 70 metres of net pay, effective porosity
of 33%, and an average hydrocarbon saturation of 59%.
A typical reservoir for CGS is a geological formation consisting of sandstone or carbonate rock characterized by 'good' effective porosity
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.
This method is limited by some factors-"ink-bottle" effect and the possibility to determine only effective porosity
which depends on the kind of pycnometric medium.
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.
However, the effective porosity
available for diffusion transport can be smaller than the value determined from the water content, since some pores may not be accessible or not contribute to the solute transport such as dead end or blind pores.
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.
