Expertise

Marcello Badalì, PhD

Marcello Badalì (PhD at the University of Alabama, US, and MS/BSc at the University of Rome, Italy) is an experienced carbonate geologist and seismic interpreter. He has more than 24 years experience in carbonate exploration-related geology (of which 15 with operators, such as Repsol and Equinor). Over the last years he has been focusing on building a new methodology (the Carbonate Seismic Scorecard, recently published in Badalì et al. 2022, AAPG Bulletin, vol. 106, p. 243-265) to recognize carbonate targets in seismic data.

He recently created his own consulting company (“Marcello Badali'”, @seismiccarbonates.com) where, besides providing training to the industry and universities, he performs interpretation of carbonates at a basin to prospect/reservoir scale, using seismic stratigraphy, sequence stratigraphy and seismic attribute imaging. He also helps assess and rank carbonate prospects and predict reservoir properties through seismic analysis, producing field/outcrop analog study and core, thin section and well-log integration.

Marcello’s expertise includes most types of sedimentary carbonate plays, which include marine/lacustrine, platform/ramp reefal (fore-reefs, back-reef and reef core), 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 GOM, S/N Mediterranean, Caribbean, Russia, West 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.

Strengths

A specialist with a professional background with an operator has a perfect knowledge of the needs of an exploration/development team.
I have 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.
I believe my clients should have a clear picture of the reasons of my working results: You will never hear me saying “This is the right interpretation because I am the specialist”. I will always explain our interpretation in the simplest possible way.
I have developed many contacts with specialists of other E&P disciplines over these many years and I have worked on a professional net that can help my 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).

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 mentioned:

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

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