Kristopher Albert Holm Innanen is being honored with the J. Clarence Karcher Award in recognition of his work in multiple suppression. Innanen has made significant contributions in the areas of multistage/multiresolution seismic migration, the development of very efficient algorithms for multiple removal, and development of higher-order imaging capability through the combination of primary processing and inverse-scattering series. Kris has pioneered the inverse-scattering series methodology in the anelastic world with the objective of Q compensation without determining or knowing Q. Much of his work has been pivotal in velocity independent imaging of subsalt, subbasalt, and subkarst areas.

The Karcher Award for Kris Innanen recognizes his important contributions to seismic forward and inverse problems. He earned his PhD under Tad Ulrych at UBC, where he received an outstanding education and mentoring in both the substance and essence of science, and an outstanding example of personal and professional integrity.

Among the topics that Kris has progressed are: (1) multiscale analysis for seismic migration; (2) modeling and processing/inversion in anelastic media; (3) forwardscattering and inverse-scattering series analogs for processing primaries; and (4) testing and evaluation of the impact of processing free-surface multiples generated from a 3D subsurface with a 2D and then a 3D free-surface multiple removal algorithm.

Kris is an important contributor to the inverse-scattering series, velocity-independent, depth-imaging campaign, and a member of the team of contributors that includes Simon Shaw, Doug Foster, Ken Matson, Bob Keys, Bogdan Nita, Fang Liu, Haiyan Zhang, Adriana C. Ramirez, Einar Otnes, and Jingfeng Zhang. He is also a key and lead researcher on the team that is bringing the promise and potential of the inverse-scattering series to the anelastic world. That promise includes direct algorithms for Q compensation without knowing or determining Q.

These fundamental high-impact research projects reside within the Mission-Oriented Seismic Research Program (MOSRP) at the University of Houston (UH) where Innanen is an assistant professor in the Physics Department/M-OSRP. The inverse-scattering isolated task subseries concept earlier provided the removal of free and internal multiples without subsurface information (e.g., P. M. Carvalho, F. V. Araujo, R. H. Stolt, R. T. Coates, K. H. Matson, A.C. Ramirez, and Sam Kaplan), and then targeted spatial location and identification, with pioneering efforts of S. Shaw, F. Liu et al., and H. Zhang et al. Removing multiples and depth imaging, target identification and increased resolution of primaries— especially in complex and ill-defined media—are among the outstanding and pressing current seismic challenges.

Innanen is a lead contributor to the effort to directly address one of the impenetrable and high priority seismic challenges: to improve the resolution of seismic images without the traditional need and requirement for a detailed accurate knowledge of the mechanism behind the degradation in resolution. Also, Jose E. Lira and Kris Innanen are part of a team that is analyzing the inverse-scattering internal multiple attenuation/removal algorithm(s) as a tool for predicting and utilizing transmission amplitude information in anelastic media.

This award recognizes and celebrates Kris Innanen’s contribution; we fully anticipate and look forward to his further progress, contributions, and success in his professional career.
