The stiffness and strength of chalks depends on pore fluids, temperature and duration of exposure.

What is it about?

We found systematic dependencies in how the mechanical properties changed. We used the experiments to expand the effective stress relation.

Why is it important?

This is important because the effective stress that drive deformation can be estimated from reservoir flow models.
