Description
This course details the internal structure, mineralogical composition and petrophysical properties of faults as well as the geological conditions (stresses) that control their tightness and integrity in faulted reservoirs. We discuss the different types of fault seals and the tools commonly used in the reservoir industry to predict fault permeability.
Major points covered:
- Fault and top seals (juxtaposition, SGR, mechanical and diagenetical seals).
- Fault zonation,
- Deformation mechanisms,
- Deformation bands in porous sandstones,
- Permeability of fault zones.
Objectives
The objective of this course is to show that from the knowledge of the structural and lithological characteristics of faults and geological conditions (lithology, porosity, stresses, diagenesis, fluid pressures), we have tools to predict the migration and trapping of fluids in the first 6 km of the crust.
Necessary pre-requisites
Structural geology,
Sedimentary petrology.
