LIVE WEBINAR – Integrated QI – the path to better predictions using seismic amplitudes

Thursday, 30 July @ 11:00 am - 12:00 pm (Australia/Perth time)

Free – $10

Guest Speaker(s): Dr Jarrod Dunne

Jarrod has more than 25 years’ experience in seismic amplitude interpretation, reservoir characterization and seismic processing, applied throughout the world, having worked for Shell, Woodside and some smaller oil companies, including his current part-time role at Karoon Energy. He has remained actively involved in R&D throughout his career: writing numerous papers; developing software; and through university collaborations. In 2018, he founded QIntegral with the aim to be recognized as a leading provider of specialist geophysical services, software, and training.

Integrated QI – the path to better predictions using seismic amplitudes


Presented by Dr Jarrod Dunne


Seismic amplitude interpretation is often referred to as “AvO” (amplitude variation with offset). This term dates to the 1980s when it was recognized that seismic reflection amplitudes sometimes increased in strength at higher incidence angles (or offsets) when gas was present in a reservoir. However, every seismic reflection has AvO, which makes matters more complicated and explains some spectacular failures using the technology.

Today we realize that seismic amplitudes and their AvO can be interpreted in terms of lithologies, fluids and other properties of economic interest. This subsurface discipline is now more commonly referred to as Quantitative Interpretation (QI), which implies that we might even be able to measure subsurface properties using seismic amplitudes.

The key to successfully interpreting seismic amplitudes is to integrate diverse geoscientific information into the analysis. Gone are the days when the QI guru was the person who seemed to understand an array of confusing maths and attributes. Seismic interpreters are probably better placed to bring all relevant information to bear on the problem at hand.

Better predictions are made when sequence stratigraphy, reservoir diagenesis, basin modelling, rock physics, and reservoir engineering information are self-consistent and used in the interpretation of seismic amplitudes. By revisiting several case studies (some successful and some not), this webinar introduces some novel ways in which geophysical, geological and subsurface engineering information can improve a QI study.
