Susceptibility, Permittivity and Dielectric Constant

Susceptibility, Permittivity and Dielectric Constant

When placed in an external electric field, a dielectric material gets polarized. The charge density in the dielectric material is given by the sum of the bound and free charge densities, while the total charge density can also be written in terms of the total electric field. The bound charge density can be measured in terms of polarization, leading to the relationship between electric displacement and polarization.

Geoscience

Background:

Determining aquifer transmissivity is crucial for groundwater management.
Traditional methods like Papadopulos' straight-line method require multiple observation wells.
Anisotropic and fractured aquifers present unique challenges in transmissivity assessment.

Purpose of the Study:

To simplify transmissivity tensor determination in fractured aquifers.
To reduce the number of required observation wells from three to two.
To validate a new method using field data from a fractured sandstone aquifer.

Main Methods:

A simplified straight-line method was developed, assuming principal directions of transmissivity are known.
Observation wells were strategically placed along the inferred principal directions from a pumped well.
The method was applied to an aquifer test in the Navajo Sandstone, Utah.

Main Results:

The simplified method successfully determined transmissivity values using only two observation wells.
Minimum and maximum principal transmissivity values were found to be 70 and 1800 m²/d.
A significant anisotropy ratio of approximately 24:1 was calculated.

Conclusions:

The simplified method is effective for estimating transmissivity tensors in fractured, anisotropic aquifers.
Knowing the principal directions a priori significantly reduces field requirements.
The Navajo Sandstone aquifer exhibits substantial hydraulic anisotropy.
