P-Velocity - Porosity Relationship, an Approach to Characterize Carbonates Reservoir, Jurassic, Cavone Field, Italy

The oil-bearing limestones of the Cavone field have been investigated to highlight the porosity types and their effectiveness, with the purpose of better characterize the reservoir and improve the production potentiality. The joint behavior of the wireline acoustic velocity and the neutron log has demonstrated to discriminate intergranular, fracture and vuggy porosities. Results are corroborated by core images at macro and micro scales. The obtained information enables the definition of new production intervals and hence sustains the field productivity.
