Pressure solution and viscous compaction in sedimentary basins
نویسندگان
چکیده
Mathematical models of compaction in sedimentary basins typically assume a relationship between effective pressure p• and porosity •, which is of a non-linear type; that is, p• = p•(d). However, at depths greater than a kilometer, pressure solution becomes important and this relationship approaches a viscous one. We derive a mathematical model for viscous compaction in sedimentary basins and show how the model suggests different styles of behavior in the limits of slow •nd f•st compaction.

Fast 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 کاملLoading and unloading of sedimentary basins: The effect of rheological hysteresis
[1] We present a model for the study of the effect of rheological hysteresis on compaction in sedimentary basins, when surface loading and unloading occurs. When compaction is slow (sedimentation rate is large and/or permeability is small), the hysteresis has little effect on the basal compaction layer, but in the more realistic case where compaction is fast (i.e., sedimentation is slow and/or ...
متن کاملOn the Compaction and Viscous Behavior of Deep-Water Reservoirs
There have been many studies on reservoir compaction where different mechanisms being suggested as the reasons behind the integrity of unconsolidated reservoirs during production. Theory of poroelasticity is often used to evaluate the likelihood of compaction under these circumstances, but it is often failed to explain the creep behavior of unconsolidated formations. In this study, attempts are...
متن کاملAnalysis of gravity anomalies with hyperbolic density contrast: An application to the gravity data of Western Anatolia
The primary objective of a gravity survey over a sedimentary basin is to delineate the shape of the basin. To fulfill this objective, information is needed about the densities within the sedimentary section. Densities of sedimentary rocks increase with depth (mainly due to compaction), approaching that of the basement in deep basins. Sedimentary basins are generally associated with low gravity ...
