Amplitude Anomalies, DHIs, AVO, Fluid Substitution Analysis for non-geophysicists
Course Type Classroom Course
Duration 4 days
Thematic Fundamentals of E&P
Why should you attend?
The course will provide full understanding of AVO/AVA theory, methodology, advantages, limits and pitfalls, boosting the technical expertise of all geoscientists with non-geophysical background. Interpreters and team leaders will achieve clear and complete vision of which is an amplitude anomaly, the most correct way to identify and de-risk DHIs on seismic, what is the AVO/AVA analysis, allowing effective early detection of seismic anomalies and improving cooperation with geophysicists.
To improve geoscientists’ knowledge and understanding of seismic anomalies
To identify potential DHIs and correctly de-risk them
To explain how, when and why to run AVO/AVA qualitative analysis
To share knowledge and experiences
Attendants will learn through live course, with hand-on practical exercises and a booklet. They will run on their own or in pairs exercises on theory of seismic reflection, seismic polarity identification, Acoustic Impedance and Reflection Coefficient calculation, DHIs identification on seismic data, qualitative analysis of AVO parameters and Classes, Intercept vs Gradient cross plot generation etc. with the help and support of the teacher.
Results will be checked at the end of each day and shared among students, to facilitate knowledge sharing. All documents are provided.
No specific requirement for this course that can take place in any meeting room with validated HSE characteristics, in your company premises or elsewhere.
Four to five days (28-35 hours) is the ideal time. The course can be shortened or lengthened according to the request.

The course is addressed to all geoscientists with non specific geophysics background, like geologists, reservoir engineers and team/project leaders involved in exploration and development projects in which amplitude anomalies play a major role. This class will provide simple, clear and complete knowledge and understanding of seismic anomalies, Direct Hydrocarbon Indicators, AVO/AVA and Fluid Substitution, allowing to run early detection of possible targets on seismic data, to de-risk a prospect and to effectively cooperate with geophysicists and specialists in reservoir characterization and fluid detection techniques.
A number of exercises and examples based on real cases and direct work experience will implement the content of this course.
Geoscientist with 30 years' experience in oil and gas exploration/development in major oil companies: ENI, Gaz-De-France, ENGIE, Neptune Energy.
Throughout these decades he was multi-disciplinary team and project leader, peer review team leader, company's key expert, chief geologist and Technical Authority for exploration geology.
He is also teacher, mentor and coach of young geoscientists, via pedagogical-educational courses and training-on-the-job activity, leading teams by doing, with technical expertise gained over the years.
His core technical background is 2D/3D seismic/structural interpretation and mapping, prospect generation and assessment, from regional play evaluation to target identification, ranking, Play Risk analysis, HIIP volumes evaluation, well location and proposal. He got a strong experience in New Venture analysis and regional or block size assessments for licensing rounds.
Piero has worked in several Countries, regions and basins throughout the world: North Sea (UK, Norway, Hollande, Germany), offshore Poland, Italy, France, Algeria, Egypt, Libya, Malta, Azerbaijan, Mauritania, Ivory Coast, Qatar, Indonesia, Malaysia, Australia, Brazil.
