Gas-prone multiphase fluids may broach or release hydrocarbons at the seafloor within a matter of decades. Lawrence Berkeley National Laboratory modeled broaching failure scenarios using Gulf of Mexico geosystems. The likelihood of broaching failure was primarily dependent on the depth of casing failure.

To better understand controls on the origin and evolution of brackish groundwater, the hydrogeochemistry of brackish groundwaters was studied within the Triassic Dockum Group across the Midland Basin in Texas. The suitability of Dockum Aquifer water for use in hydraulic fracturing fluid was examined because the area overlies the largest and most productive tight oil province in the United States.
