Mineral diagenesis, causes and consequences
Synthesis
The history of the burial process and its consequences on the porous network in terms of: – petrophysical characteristics,- mineralogical developments.
Understanding the evolution:
1) The tools:
– mineralogy (silicates, carbonates and sulfates),
– stable isotopes (carbonates, sulfates and formation water),
– unstable isotopes (K/Ar) and age dating phenomena,
– defects in crystals (fluid inclusions and traces of fission),
2) Compiling tool findings to place an event:
– in time,
– in a given temperature bracket,
– in a given pressure bracket.
Synthesising the association of tools, the dynamic diagenetic sequence, time, temperature and pressure, as well as porosity and permeability.
Language
Audience type
– This talk can be adjusted to suit the audience’s level. – Students in earth-sciences courses starting at MSc level and up to ScD level, engineers from leading schools. – A course with a more operational slant for engineers and technicians involved in exploration operations.
Planned duration
The talk lasts three hours but should, ideally, include a further three hours discussing practical examples from studies.
Support material
PowerPoint slides on a CD.
