Basic data visualization in vintage seismic profiles: Indications for the interpretation of the ViDEPI database (offshore Puglia, southern Italy)

Abstract

The Visibility of Petroleum Exploration Data in Italy (ViDEPI) project represents a freely accessible valuable resource for the research community. However, seismic profiles available from this project present several limitations because information such as the basic shape of the seismic wavelets and the seismic polarity are not available. In this study, using subsurface (i.e., 2D seismic profiles) data related to the Marine Zones B, D and F (offshore Puglia) a review of the basic pulse shape and polarity of seismic wavelets, as well as the shape and polarity of principal reflectors has been addressed. Moreover, borehole data (i.e., lithology and sonic logs) have been used to identify abrupt average velocity changes linked to different lithostratigraphic successions recorded as dominant high-amplitude reflectors.

In the ab sence of the sonic log for the Picchio-1 explo ra tion well, av er age ve loc i ties were cal cu lated by con sid er ing both the thick ness of the lithostratigraphic units drilled and the related two-way-times (TWT) val ues on the seis mic pro file F83-104 (Fig.…”

“…The ability to freely access these subsurface data significantly stimulated research on the tectono-sedimentary evolution of the Apulian Foreland-foredeeps system during the Cenozoic involvement of the Adria plate in the Dinarides–Hellenides (to the east) and Apennines (to the west) orogens ( Fig. 1a ) [ 3 , [5] , [6] , [7] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] ].…”
