In this lab, students first investigate the processes involved in unconventional oil and gas resource production, i.e. hydraulic fracturing, including examining the regions in the US where hydrofracking is being conducted. They then compare those regions to the geology and recent seismicity on a US scale. The next step is for the students to conduct a detailed comparison of hydrofracking wells, waste water disposal wells, and seismicity on Oklahoma. They are asked to decide if they can draw correlations between fluid injection related to hydrofracking or from wastewater disposal and earthquake activity, and to consider ways that we might establish a better understanding of correlations between the two. Finally they are asked to make a claim, backed up by evidence, as to whether there is a causal link between any of the correlations.

Students will be able to
1. Describe the processes involved in unconventional oil and gas production.
2. Collect and analyze seismicity data for a region of interest using the IRIS Earthquake Browser.
3. Use data to either support or refute potential correlations between hydrofracking and/or disposal wells and earthquakes in Oklahoma.
4. Describe how other processes, such as geothermal energy might similarly induce seismicity.
