Consolidation and Pore Fluid Pressure of Ursa Sediments, Deepwater Gulf
15 We conducted uniaxial compression tests on whole core samples from the Ursa 16 Basin, deepwater Gulf of Mexico, to obtain the consolidation properties of mudstones. 17 We showed that specific volume (v = 1+e) (where e is void ratio) declines as an 18 exponential function of effective stress and we used this relationship to successfully 19 predict in-situ pressure from void ratio at IODP Site...
متن کاملEnvironmental change, hydrate dissociation, and submarine slope failure along continental margins: the role of saturation anomalies in landslide triggering
Submarine landslides occur along active and passive continental margins and are potentially triggered by numerous factors including the dissociation of gas hydrates. The hazard produced by such landslides can damage infrastructure (oil platforms, telecommunication lines), generate tsunamis, and cause a catastrophic release of methane to the atmosphere and ocean. Here we develop numerical models...
متن کاملHydrodynamics of the Us mid - Atlantic Continental Slope , Offshore New Jersey A
Fluid pressures in Miocene-Pleistocene sediments of the US mid-Atlantic continental slope approach the lithostatic stress and are an important control on the stability of the slope. Fluid pressures in excess of hydrostatic were generated by regional depositional patterns and sedimentation rates. Fluid migration within porous and permeable Miocene silty sand layers redistributed pressure and gen...
متن کاملRisk Assessment and Management for Offshore Geohazards
The state-of-the-art in understanding offshore geohazards has advanced significantly in the past decade. The advances have been mostly driven by the needs of the offshore petroleum industry. The pace of exploration and field development on the continental slopes and in ultra-deep waters worldwide has increased rapidly during the past decade. Activities are concentrated in areas where the sedime...
