7) a) In Figure 7.5, there are alternating layers of aquifers and aquitards (shale cap rock). Using your knowledge of how long it takes for fluid to move through and across different materials (refer to the groundwater lab), describe whether or not the labeled confined aquifer is at risk for contamination from migrating petroleum molecules. Include the importance of porosity, permeability, and conductivity in your answer. b) is the aquifer more or less at risk for contamination due to petroleum extraction operations? Explain your answer.

Oil and gas molecules form in organic-rich source rocks and eventually become trapped in permeable aquifers. Vertical wells are then used to extract the oil and gas. Today, horizontal drilling and hydraulic fracturing techniques allow oil and gas to be extracted directly from source rocks and other rock layers with low permeability. (rei22967_13_13)
