Thoroughly enjoyed watching your lecture. Just wondering on one aspect; is it the viscous force that keeps mud from easily dissipating water? because viscosity is the property of the fluid and in both cases, it is the same fluid - brine/water.
In the case of disequilibrium compaction, brine/water viscosity combined with small pores in mudrock prevents brine going quickly through mudrocks. Mudrocks are quite stiff and strong at high levels of effective stress in the subsurface, quite different to poorly compacted mud we often see on surface.
Considering carbonates, due to existence complicated thermo-hydro-chemical coupling effects deals with over-pressure creation, normally straight-forward calculations, as it applicable to shale and sand formations, does not accurate enough in many cases. It would be great if the lecture has some tips for carbonates pore pressure estimation.
Thanks for the comment! I will try to add some simple models in the future. Thermo-hydro-chemo-mechanical coupled processes are covered in my Advanced Geomechanics lectures.
Thank you
