Talk Title: AVO Dark Arts and Quantitative Interpretation: A review of theory and practise

Talk Overview:

Amplitude variation with offset or angle can be a powerful interpretation tool, but the theory behind the various interpretation techniques can seem opaque and off-putting to many practising geophysicists. This presentation will provide an introduction to AVO theory, techniques and quantitative interpretation (QI) pitfalls illustrated with an Otway Basin example.

The Eastern Otway Basin is known for its very strong DHI responses across most of the gas fields discovered there. In particular, the far stack and fluid factor response standout as key gas indicators. However, the Minerva field is an exception to the rule. Can a more detailed analysis of the field explain the anomalous amplitude response through the crest of the field and what can we do to better identify gas accumulations with other QI techniques?

About the Speakers:

David Close

David Close is currently the Unconventional Exploration Manager and Chief Geologist for Origin Energy in Brisbane, Australia. He holds a Ph.D. from the University of Oxford and a B.Sc. from the University of Tasmania. David worked in Mexico, U.S.A and Canada for Schlumberger and Apache Canada prior to joining Origin. David has worked in a range of conventional and unconventional exploration roles and has developed expertise in unconventional resource exploration and evaluation, and quantitative seismic interpretation. David is a member of PESA, ASEG, SEG, and AAPG

Tony Hallam

Tony Hallam has been a geophysicist with Origin Energy for 6 years. Starting in a functional team he gained exposure to many of Origin’s assets including conventional and CSG. The last 3 years have predominantly been spent working Origin’s offshore conventional assets on the southern margin where he has contributed to exploration via interpretation both structural and quantitative, seismic processing QC, P&L generation and risking and the development of an upcoming exploration and development drilling campaign.
