Abstract: Modeling Cyclic Fluid Release From A Growth Fault in Geopressured Sediments, Eugene Island Block 330 Field, Offshore Louisiana, Gulf of Mexico

C. R. Wilkinson, R. N. Anderson

The model includes a fault permeability mechanism wherein (log k) is proportional to excess pore pressure between the limits of the fracture reopening pressure and the fracture closing pressure. These values have been estimated from hydraulic fracturing tests.

Fault reopening results in the release of fluids from geopressure at 1-4 m/y, and predicted temperatures match those observed. The pressures which drive these high flows can last for several hundred years. The time to rebuild these pressures is on the order of thousands of years.
