What Should Multicomponent Near-Surface Corrections Look Like in a World of Waveforms?: A raypath-consistent solution for converted-wave processing

Raul Cova, David Henley, Xiucheng Wei and Kristopher A. Innanen

Removal of near-surface effects from elastic data, particularly converted waves, is a well-known and difficult problem, whose difficulty only increases on the backdrop of the trend in our field towards treating seismic wiggles as full waveforms. If we want to eventually apply some type of full waveform inversion or fitting,…

Interbed Multiple Prediction on Land: Which Technology, and Which Domain?

Jian Sun and Kristopher A. Innanen

Prediction and removal of internal or interbed multiples is an increasingly high priority problem in seismic data analysis. One reason for the growth of its role and importance comes from the increased sensitivity with which primary amplitudes in quantitative interpretation are now analyzed. But the importance of accurate and robust…

Reflections from Contrasts in Isotropic Attenuative Media AVO and Beyond

Shahpoor Moradi and Kristopher A. Innanen

The purpose of this article is to summarize and illustrate some features of new theory describing the interaction of seismic waves with viscoelastic structures and interfaces. Progress in these areas makes available more sophisticated tools for AVO analysis and inversion, and thereby quantitative interpretation, and for multi parameter full waveform…

A Summary of Several Challenges Facing Multi-Parameter Elastic Full Waveform Inversion

Wenyong Pan and Kristopher A. Innanen

In spite of all that there is still to learn about seismic full waveform inversion (FWI), and there is a lot, the technology has accumulated some significant success stories in recent years – enough to motivate researchers to think quite ambitiously about how far we might go with it. Moreover,…

Mental Casualties of a Down-turned Market

Amanda Knowles

Aaron sighed, “I lost my job in December and I can’t find anything else.” His statement hung in the air for what seemed like an eternity. I struggled to find the right words to say. How could I help? What could I possibly do? My company wasn’t hiring and I…

Support Services Available for Those Facing Mental Health Challenges

Rob Holt

In any given year, at least one in five people in Canada experience a mental health problem or illness, and most of us know someone who has faced a mental health challenge or concern. Mental illness does not discriminate based on age, gender, religion or race. Mental illness can be…
