Porosity and Permeability

Porosity: percentage of open (pore)

space in a rock

Permeability: ability of fluid to move

through pores

slide2

Porosity

Fill a swimming pool with marbles

Fill a swimming pool with tennis balls

Which will have the greater porosity?

slide3

Porosity

Which will have the greater porosity?

slide4

Marcellus Shale is an example of an

unconventional reservoir rock:

it possesses porosity but lacks permeability

slide11

Employment for Geologists

“Employment growth of 18 percent is expected for geoscientists and hydrologists between 2008 and 2018, which is faster than the average for all occupations. The need for energy, environmental protection, and responsible land and water management will spur employment demand.”

--US Dept. of Labor, 2010-2011
