WebRock compressibility is not measured in a conventional core analysis, but can be determined using hydrostatic or triaxial tests. In these tests, the core section is sealed in a rubber … Web5 Jun 1998 · The unjacketed core compressibility in a porous rock is the change in pore volume due to change in pore pressure for constant differential pressure. This parameter affects how the saturated bulk modulus of a rock is related to the drained frame modulus and the pore fluid compressibility.
WebThe foundation conditions of rocks and soils are an important consideration for determining how surface construction loads are transmitted into the ground safely and for the lifespan of the project. The main considerations are: strength or bearing capacity settlement (compressibility) and differential settlement Web1 Jan 2011 · Aloki Bakhtiari et al. (2011) assessed the dependency of pore volume compressibility on effective stress in limestone samples at different confining pressures (up to 35 MPa) using an automated...
Web14 Sep 2024 · Rock compressibility is crucial for deriving the effects of reservoir compaction using, typically, the Geertsma (1973b) equation that itself is representing the deforming reservoir in the subsurface as a nucleus of strain inside an isotropic elastic half-space (cf. Eshelby, 1957 ).
