• 11669 Environmental Implications of the Shale Gas Revolution and Associated Hydraulic Fracturing Shale gas and associated hydraulic fracturing or “fracking” has become a hot-button environmental issue in the United States and around the world. The purpose of this talk is to provide some background geological and engineering information on the issue and to take a more in-depth look at some of the environmental pros and cons of shale gas development.

• 11670 Fault-Related Hydrothermal Alteration of Carbonate Reservoirs Hydrothermal alteration occurs when relatively high-pressure, high-temperature fluids flow up active faults and into permeable formations that underlie sealing shales, or other low permeability strata. This process can and commonly does occur at relatively shallow burial depths of less than a kilometer and in many cases less than 500 meters.

• 11671 Shallow Seasonal Anoxia Model for Organic-Rich Mudrocks: An Alternative Hypothesis Organic-rich marine mudrocks are commonly interpreted to have been deposited in deep, quiet, permanently anoxic basins. While this appears to the case in some modern and ancient examples, field relations, regional correlations and sedimentological observations show that at least some widespread organic-rich may instead have been deposited in relatively shallow (<50 meters), moving water that at times had enough oxygen to support at least some life on the sea floor.
