The relation between static and dynamic stiffness in shales is important for many engineering applications. Dynamic stiffness, calculated from wave velocities, is often related to static stiffness through simple empirical correlations. The reason for this is that dynamic properties are often easier ...

Time-lapse (4D) seismic is often used for monitoring hydrocarbon fields during depletion and injection processes (hydrocarbon production, enhanced oil recovery, or CO₂ storage operations). When the reservoir pore pressure changes during production or injection, the formation stresses in reservoir an...

Shale rock physics may be used for improved monitoring of subsurface changes in and around a depleting reservoir. It is shown how rock physics plays a key role in interpreting time-lapse (4D) seismic into geomechanical attributes as changed stresses, strains and pore pressure. This knowledge is of i...

In this work, an experimental study was carried out with the aim of linking static and dynamic stiffness of shales. Four fully saturated field shales were tested. The experiments were carried out in SINTEF's low-frequency cell. The measurements included undrained quasi-static loading cycles from whi...

Since shales are the far most abundant overburden formation, understanding the geomechanical and rock physics behavior of shales is essential. We discuss a particular deep overburden shale in light of a thorough static and dynamic multi-directional data acquisition, as a basis for complete static an...
