Determination of Permeability from Damping
- Technology Benefits
- Improves the accuracy and effectiveness of drilling for oil and water. Determines permeability faster saving money as a result of not having to calibrate to local conditions. Knowing the permeability of a saturated material improves your ability to get fluid out. The invention senses beyond the immediate borehole.

Title: Determination of permeability from damping
Usefulness: Determination of permeability from damping
Summary: Method for determining permeability of fluid through fluid-saturated solid material. Uses include but are not limited to oil well production process, grouting process for soil improvement, contaminated soil treatment process, water wall production process and/or landfill waste disposal process.
Novelty: Method for determining permeability of fluid through solid material for, e.g. oil well production process, involves performing vibration testing of sample of fluid through solid material, to determine Kelvin-Voigt damping ratio

- *Abstract
-
Permeability generally means the ease with which fluids can move through rock, soil, or other earth materials. Boise State University has developed new methods, apparatus, and/or programming for determining the ability of a fluid to flow through a saturated material by measuring the dynamic response of the saturated material to shaking vibrations or shear wave propagation. Using this measurement, the permeability of the material can be mapped. The invention may use shear waves, inertial effects, and/or transmission effects to force the fluids through the pores of the material. This technology differs from previous methods in that it is consistent and directly related to the laws of physics rather than depending on local calibrations. This method will be useful for several applications ranging from production in oil wells and water wells to treatment of contaminated soils and waste disposal in landfills.
