Nuclear Magnetic Resonance Six Miles Deep: Physics in the Oil Industry
NMR is a technique used to determine the porosity and permeability of rock formations.
 
Science Lab
The Absorbency of Rock
Rocks are not as solid as you may think. They may be able to soak up liquids just like a sponge.
The Permeability of Soil
See how soil permeability affects the behavior of rainwater when it hits the ground.
Porosity
Here's another experiment that takes a look into the spaces between the grains that make up stone.
The Brazil Nut Effect
Why do the Brazil Nuts seem to end up on top of the others in a can of mixed nuts, and what does this have to do with sandstone and oil production?
Building the Hele-Shaw Cell
Here are plans and directions for building the apparatus used by Hernán Makse in the Stratification & Segregation experiments.
