Multi-component (aka converted-wave, aka PS) data is a bit of an enigma.  It’s like poetry; we know it’s important and we want to appreciate and understand it, but it’s hard work and the encounter can leave us a little bewildered and secretly disappointed.  What was all the fuss about?, we ask.  I think the key is to keep an open mind and, like all seismic interactions, let the sound waves speak for themselves in their native tongue.  Just as French poetry loses something in the translation to English (I’m told), so does PS data when we convert (clumsily, I might add) to PP time.  Let’s not be too quick to register!

In this presentation, I will share other metaphors, opinions, and even examples from real  case-studies to illustrate how this type of data can be gently coerced into making valuable contributions to the prediction of rock and fluid properties.


Laurie started her career with Shell Canada doing seismic processing and interpretation in the central plains area of Alberta. Seeking adventure and travel, she took a position with LASMO plc in London, to work on various European, North African and Middle East projects. She later returned to Canada after working at Wascana Energy in London, to work domestic cold-flow heavy oil projects.   

Shortly thereafter, she began her consulting career with Alberta Energy (AEC) in 1999 and has contracted for a number of companies and projects. Laurie began a consulting contract with Nexen Canada Inc. in 2000 in their Synthetic Oil group, where her main professional interest became the Canadian oil sands. She formed Oil Sands Imaging in 2007 to optimize seismic value for clients. Oil Sands Imaging evolved into Sound Qi which was subsequently taken over by Canadian Discovery Ltd.         

Laurie was the CSEG Technical Co-Chair of the Recovery 2011 Convention and has received honorable mention for the CSEG's Best Technical Luncheon Speaker award in 2008. She also received the CWLS President's Award for best technical luncheon talk in 2006 and the CSPG/CSEG Convention's best integrated core presentation award in 2007.
