Figure 6.3 – Conceptual structural reservoir prospective of the Favignana calcarenite. A cross
section from northwest to southeast is given, with Favignana on the right. Vertical scale is
exaggerated.
Table 6.2 – Results of the volume calculation of the potential Favignana oil reservoir. BV is
the bulk volume, PV the pore volume and HCPV is hydrocarbon pore volume — or the pore
volume occupied by hydrocarbons. All volumes are in [106 m3].
