Compression behavior of smectitic vs. illitic mudrocks

Overpressure or fluid pressure in excess of hydrostatic pressure has been observed globally in many deep water sedimentary basins. One of the possible mechanisms for overpressure is the smectite-to-illite (S-I) transformation. During the transformation, the basal spacing of the smectite layer reduces. The interlayer water is released into pore space, causing an increase in pore pressure. This thesis investigates the compression and permeability behavior change due to S-I transformation. Uniaxial compression testing was performed on smectitic and illitic mudrocks. The original Gulf of Mexico - Eugene Island (GoM-EI) mudrock sets the baseline for smectitic mudrock in order to compare with illitic mudrocks. Two methods were used to create illitic mudrock from the GoM-EI sediment.
