Patrick Connolly is a consultant geophysicist specializing in seismic reservoir characterization.  He retired from BP in 2015 as Senior Advisor for Geophysical Analysis.  His primary occupation now is providing training courses for the industry.  He is also a Visiting Lecturer at the School of Earth & Environment, University of Leeds, UK.

Patrick has over 40 years industry experience, including 15 years in research in both technology management and R&D project leadership, 10 years as an analyst/interpreter in exploration and appraisal teams in the North Sea/West of Shetlands, Gulf-of-Mexico and offshore West Africa, 10 years programming and 3 years as a data processor.  He was awarded the 2001 SEG Virgil Kauffman Gold Medal for the development of elastic impedance.  He was an EAGE Distinguished Lecturer in 2007, an SEG Distinguished Lecturer in 2010 and his presentation Probabilistic seismic inversion using pseudo-wells was awarded the 2017 SEG Best Paper at the Annual Meeting.


This course examines the information content of seismic amplitudes; what can be measured, what causes errors in these measurements what is the impact of these errors.  It will consider how much information is encoded within seismic amplitudes; what can we invert for, to what extent uncertainties can be quantified and how geological context affects uncertainties.  The course will demonstrate that clarity about what it is possible to estimate, rather than what we’d like to estimate, leads to better algorithms and better QI work-flows.

This is a one-day classroom based course delivered at an intermediate level.  Participants should have a good knowledge of the seismic method, including acquisition and processing and basic QI including AVO.
