Fluid Storage and Mobility Porosity and permeability involve the ability of rocks/sediments/soils to contain fluid and to allow fluids to pass through them Porosity – the proportion of void space (holes and/or cracks) in material (soil or rock) where fluid can be stored Usually expressed as a percent (1.5%) or a decimal (0.015) of the entire volume Pore space can be occupied by fluid or gas

Fluid Storage and Mobility Permeability – measures how readily a fluid passes through a material Measures degree of interconnection between pores and cracks in rocks and soil Grain shape and size are factors How grains fit together influences permeability also Porosity and permeability play a big role in groundwater hydrology, oil and gas exploration, and nuclear waste disposal

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
