文摘
- •
A workflow is proposed for the petrophysical evaluation of highly heterogeneous lithofacies.
- •
The evaluation is performed individually for each type of elementary lithological component.
- •
Measurements include 2D mapping of profile permeability and microhardness at the core-scale.
- •
Procedures for the volumetric population of these properties in the cores are explained.
- •
Relationships between porosity, permeability, and microhardness are investigated.
