The overburden stress
WebbFigure 1: vertical stresses in the formation. The weight of the overburden is supported by (1) the vertical grain-to-grain matrix stress and (2) the pore fluid pressure. Because the rock is static, the forces must be in static equilibrium with each other. The system of rock grains can be packed in different configurations so it can be difficult ... WebbOverburden stress can be easily obtained from bulk density logs and empirical equations (refer to Section 6.1), while effective stress can be correlated to seismic velocity and …
The overburden stress
Did you know?
Preconsolidation pressure is the maximum effective vertical overburden stress that a particular soil sample has sustained in the past. This quantity is important in geotechnical engineering, particularly for finding the expected settlement of foundations and embankments. Alternative names for the preconsolidation pressure are preconsolidation stress, pre-compression stress, pre-compaction stress, and preload stress. A soil is called overconsolidated if the current effective s… WebbThe fracture pressure of a borehole depends on the in situ stress state, which is defined in terms of a three-parameter tensor: the overburden stress σ v and the two horizontal …
WebbThe expression for the Pseudo-Overburden Stress wi-thout considering water column is presented as follows: The calibration of this method is based on data obtained from off-set wells with the same target formation or eventually in formations with similar characteristics. The Pseudo-Overburden Stress Method is presented as follows: 1. Webb16 apr. 2024 · Effective overburden stress: the effective stress on the soil skeleton, which is calculated by subtracting the pore pressure from the overburden stressOver-consolidation ratio: the ratio of past maximum effective overburden stress to present effective overburden stress. (Consolidation refers to a process in which soil decreases …
