Paper Number: SPE-78172-MS
... for the determination of in-situ stresses via micro-HF tests. Hubbert and Willis 1 derived the elastic formula for the breakdown pressure in the case of impermeable materials. By considering the poroelastic effect, Haimson and Fairhurst 2 derived a similar expression for the case of permeable formations. Those two...

Paper Number: SPE-78155-MS
... Abstract An accurate knowledge of porosity and permeability is crucial to accurate simulation of reservoir performance and enhanced reservoir management. Porosity and single-phase permeability of reservoir rocks is dependent on the stress experienced by the rock mass, which in the simplest...

Paper Number: SPE-78188-MS
... Abstract Qualitative determination of formation permeability is often obtained through laboratory flow tests on core plugs. However, the experimental determination of the permeability for anisotropic plugs (particularly the horizontal permeability) is difficult and less than perfect; generally...

... is not likely to occur. Deformation is dominated by compaction. Our analysis estimates that porosity of the formation was reduced from about 23% to 21%, while the permeability was reduced from about 230md to 50–140md. Introduction The deformation mechanisms operative in a depleting reservoir are important...
