Ghassemi Holds a Core Sample (IMAGE)
Caption
In Ghassemi's Rock Mechanics Lab, rocks are put to a variety of tests to determine their characteristics and response to injection. Ghassemi holds a core sample with a natural fracture that was tested with acoustic emission (seismicity) monitors used in the testing. The large, square rocks will be put in a machine to simulate the pressure deep in the Earth. The square shape will allow Ghassemi and his team to put stress on the rock in three axes, making the hydraulic fracturing tests further resemble conditions deep beneath the Earth's surface.
