Fracture Sequence and Loading Path in Folded Carbonates of Albania Foreland

Fractures in rocks are sensitive cursers that may enhance porosity and permeability in reservoirs. This is especially true in carbonates because background fractures might be ubiquitous after embrittlement at early burial.). Barren fractures at depth are susceptible to chemical reactions with underground fluids and cementation that might totally or partially reduce porosity and permeability for hydrocarbons and fluids. In foreland basin carbonates of Albania, reservoirs are strongly influenced by fractures, faults and folds all having a complex 3D arrangement.

We realized a fracture sequence, harmonized with the loading path and tectonic calendar. With the analysis of scales imbrication and structural diagenesis, we show how faults and fractures contribute to the fluid flow at several scales and times of the reservoir history.
