Unlike man made materials such as concrete, steel, etc, natural materials such as rocks and soils are subject to natural (virgin) stresses called in-situ stresses. Knowledge of the in-situ stress field is very important in many problems dealing with rocks in civil, mining and petroleum engineering as well as in geology and geophysics. The last 30 years have seen a major advance in our knowledge of in-situ stresses. A large body of data on the state of stress in the near surface of the Earth’s crust (upper 4-5kms of the crust) is now available. New theories have been proposed rega

Mechanical properties and fluid transport in rocks are intimately linked as deformation of a solid rock matrix immediately affects the pore space and permeability. This may result in transient or permanent changes of pore pressures and effective pressures causing rock strength to vary in space and time. Fluid circulation and deformation processes in crustal rocks are coupled, producing significant complexity of mechanical and fluid transport behavior. This often poses severe technical and economic problems for reservoir and geotechnical engineering projects involved in oil and gas production,
