QI stands for Quantitative Interpretation, relating primarily to the analysis and interpretation of seismic data. From the perspective of an engineer, seismic data may seem remote and unfamiliar; maybe even irrelevant. However, it is a source of very detailed information about the reservoir that can contribute to a more complete understanding of reservoir properties and, ultimately, performance. We never know as much about the reservoir as we would like. Therefore models calibrated to data but generously coupled with conceptual understanding are necessary. This is the case regardless of the type of data or problem to be solved. The QI approach is in fact quite general and applies equally well to solving engineering problems as it does to seismic data problems. In both cases, we are extrapolating from the known to the unknown and making decisions based on these inferences.


QI can be a mysterious process even to geophysicists. It involves sophisticated geophysical operations and multiple boot-strapped steps in a complex workflow. However, the integration of the deliverables of QI is the objective of this discussion. Let’s assume that the sophisticated geophysical operations have already been done by sophisticated geophysicists and that the team has confidence that the analysis process has been completed thoroughly and correctly. Unfortunately, though, that is where the integration stops for many; with multiple seismic volumes representing months of work, sitting in a drawer.


The main reason for that disconnect is a lack of understanding on both sides of what the seismic analysis represents, what it doesn’t represent, and how to use it with confidence in an integrated model of the reservoir.


I intend to explain the QI method in general terms, how it is applied to seismic data, what the outputs mean and how they can complement other information about the reservoir from well and production knowledge. At the same time, the QI method itself can be applied to reservoir management. The combination of the additional detail from seismic data and, in turn, refocusing the method will give engineers new insights and new tools to make better decisions based on superior understanding of the reservoir.

Speaker Bio:

Over her 30 year career as a geophysicist, Laurie Weston has seen the oil and gas industries from many perspectives. She has been part of the evolution of exploration objectives and analysis techniques, both as a scientist and an entrepreneur.


Laurie’s career began with Shell Canada in Calgary doing seismic processing and interpretation in the central plains area of Alberta. Looking for adventure and travel, she took a position with LASMO plc in London, to work on various European, North African and Middle East projects. Upon her return to Canada, Laurie consulted with Nexen Canada Inc. before founding her own seismic consulting company in 2007. The company, called Oil Sands Imaging, was later re-branded as Sound QI and sold to Canadian Discovery in 2012. In early 2017, Laurie acquired the QI business from Canadian Discovery and re-started Sound QI.
