Course Description

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.


Patrick Connolly is a consultant geophysicist specializing in seismic reservoir characterization.  After a lengthy career, largely with BP, he retired in 2015 as BP Senior Advisor for Geophysical Analysis.  He now runs his own company providing training courses to the industry.

Patrick began his career as a data processor and then programmer before a move into analysis and interpretation in exploration and appraisal teams in offshore West Africa, Gulf-of-Mexico and the North Sea / West of Shetlands. It was here that he developed the elastic impedance concept for which he later received the SEG Virgil Kauffman Gold Medal.  He was also a co-developer of Extended Elastic Impedance now widely used throughout the industry.  During the latter part of his career Patrick spent time in technology management and R&D project leadership where he developed the seismic net pay method and the probabilistic inversion application ODiSI.  Patrick served as an EAGE distinguished lecturer in 2007 and 2018 and a SEG Distinguished Lecturer in 2010.
