Accommodation Space Transformation System in Faulted Basin
The variation of accommodation space in faulted basin is mainly affected by three factors: the differential subsidence of basement, the deposition of sediments and the variation of absolute lake level. In this article, the variation laws of accommodation space have been analyzed and its distribution characteristics have been explained when the lake level is descending, still and ascending and t...
متن کاملGeneration of overpressure and compaction-driven fluid flow in a Plio-Pleistocene growth-faulted basin, Eugene Island 330, offshore Louisiana
The complex pressure and porosity fields observed in the Eugene Island (EI) 330 field (offshore Louisiana) are thought to result from sediment loading of low-permeability strata. In this field, fluid pressures rise with depth from hydrostatic to nearly lithostatic, iso-pressure surfaces closely follow stratigraphic surfaces which are sharply offset by growth-faulting, and porosity declines with...
متن کاملSeismic Geomorphology of Oligocene Frio Lowstand Slope and Basin-Floor Sedimentary Bodies in Growth-Faulted Subbasins in South Texas
Architecture of slopeand basin-floor-fan systems in growth-faulted subbasins along the south Texas Gulf Coast developed as a result of interplay between synsedimentary tectonics and sedimentation during third-order sea-level lowstands. These subbasins, or intraslope basins, have not been adequately explored for their slope and basin-floor-fan potential, as have the intraslope basins in salt-dom...
متن کاملFast and Slow Compaction in Sedimentary Basins
A mathematical model of compaction in sedimentary basins is presented and analyzed. Compaction occurs when accumulating sediments compact under their own weight, expelling pore water in the process. If sedimentation is rapid or the permeability is low, then high pore pressures can result, a phenomenon which is of importance in oil drilling operations. Here we show that one-dimensional compactio...
متن کاملHelium flux from a sedimentary basin.
The tritium-3He ages of groundwaters collected from the Saijo Basin in Japan were measured. The ages vary between 11.7 and 16.3 years. The 4He flux of >3 x 10(4) atoms/cm2 s is calculated by the 4He concentrations and ages. In addition the helium flux of 8.3 x 10(5) atoms/cm2 s is calculated at the Higashi-Niigata gas field in Japan. The above two estimates are consistent with the continental h...
