Our research on structural diagenesis is supported by Chemical Sciences, Geosciences and Biosciences Division, Office of Basic Energy Sciences, Office of Science, U.S. Department of Energy with initiation funding from JSG Structural Diagenesis Initiative of the Geology Foundation, John A. and Katherine G. Jackson School of Geosciences (2005-2008).

Research on all aspects of subsurface fractures is supported by Industrial Associates of the Fracture Research and Application Consortium and by Jackson Research Fellowships.

The Fracture Research & Application Consortium supports a wide range of student projects focused on fractured shale, sandstone, and carbonate rocks. Major studies are underway in Colorado, Wyoming, East Texas, and Argentina.

For information on student and postdoctoral opportunites see the Structural Diagenesis page.
