Marcello Badalì, PhD

Marcello Badalì (PhD) is an experienced carbonate geologist and seismic interpreter. He has 25 years’ experience in exploration-related geology (of which 15 years with operators, such as Repsol and Equinor). He built a new methodology (the Carbonate Seismic Scorecard, recently published in Badalì et al. 2022, AAPG Bulletin, vol. 106, p. 243-265) aimed at recognizing carbonate targets on seismic data. His most recent research has focused on the investigation of the evolution of the seismic expression of carbonate systems over geologic time, from Precambrian to present day, and it was published in the SEG/AAPG journal “Interpretation” (Badali’ 2024, Vol. 12, No. 2, T119-T147).

He performs interpretation of carbonates at a basin to prospect/reservoir scale, integrating seismic stratigraphy, sequence stratigraphy and seismic attribute imaging with sedimentology and petrographic analysis. He helps assess and rank carbonate prospects and predict reservoir properties of carbonate sedimentary and diagenetic (including fractured) plays, through seismic analysis, field and outcrop analog study and core, thin section and well-log integration. Last, but not least, he provides training for industry and academia on characterization and seismic recognition of carbonate prospects and plays.

Marcello’s expertise includes most types of sedimentary carbonate plays, which include marine/lacustrine, platform/ramp reefal, lagoonal and shoal/bank systems, resedimented carbonates (such as calciturbidites, debris and breccia bodies) and evaporite systems, as well as the main types of carbonate diagenetic plays, like fresh-water karst, early and hydrothermal dolomites, and (shallow-water and pelagic) fractured limestones.  Also, where possible, potential source rock layers can be mapped.

During his career he has developed an extensive and worldwide (e.g. SE Asia, Middle East, Mex/US Gulf of Mexico, S/N Mediterranean, Caribbean, Russia, West Africa, North Africa, Southern Atlantic, Black Sea, Portugal, Ireland) project expertise in Proterozoic, Paleozoic, Mesozoic and Tertiary carbonate plays.

Marcello is fluent in English, Spanish, French and Italian.

Geographic expertise

(One dot can be related to more than one project)


  • A specialist with a professional background with an operator has a perfect knowledge of the needs of an exploration/development team.
  • Marcello’s expertise is an uncommon combination of a solid carbonate sedimentology and petrography background and remarkable carbonate seismic interpretation skills.
  • Marcello has developed the Carbonate Seismic Scorecard, and such a tool can be created only thanks to an extensive exposure and study of thousands of seismic images of carbonate and biasing structures, which makes this a top consulting company in this discipline. 
  • Marcello believes clients should always have a clear picture of the reasons of his working results: You will never hear him saying “This is the right interpretation because I am the specialist”. He will always explain his interpretation in the simplest possible way. 
  • Marcello has developed many contacts with specialists of other E&P disciplines over these many years and he has worked on a professional net that can help his clients to find reliable technical support in other disciplines when needed (see bottom of this page).

The Seismic Carbonate Scorecard

The SCS is a proprietary tool which was designed to help distinguish, on seismic data, shallow-water carbonate structures from similar, non-carbonate structures, such as volcanoes, basement highs, erosional remnants and various tectonic features (Badalì et al., 2022, AAPG Bulletin). 

This tool allows to “score” fifteen parameters from a seismic image, resulting in a final quantitative score which indicates the chance of dealing with a carbonate (positive score) or a non-carbonate (negative score) structure.

The effectiveness of the SCS concept was proven during a massive test on more than 200 images of different structures, which were scored by a non-carbonate, junior geologist, whose interpretation, in 90% of the cases, matched the drilled/calibrated/interpreted nature of the structure (Badalì et al., 2022). This tool, as a matter of fact, was built to give the possibility to non-specialist geoscientists to assess seismic images of potential carbonate prospects without the assistance of a carbonate interpreter. 

Nevertheless, some points should be highlighted:

–  This scorecard, beside requiring some training before its use, will never replace an experienced specialist.

–  In Marcello’s consulting activity, this can be a powerful tool to risk-rank potential carbonate prospects, if needed or required by the client; however his overall carbonate assessment rather focuses on the integration and analysis of all available data and he does not use the SCS as his main and only reference.
