  1. Porosity and Permeability Porosity: percentage of open (pore) space in a rock Permeability: ability of fluid to move through pores

  2. Porosity Fill a swimming pool with marbles Fill a swimming pool with tennis balls Which will have the greater porosity?

  3. Porosity Which will have the greater porosity?

  4. Marcellus Shale is an example of an unconventional reservoir rock: it possesses porosity but lacks permeability

  5. 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

  6. Salaries for Geologists (2008 data)

  7. Environmental Challenges • of Marcellus Development • Groundwater Protection • Surface Land/Water Protection • Earthquakes
