Biography

Dennis Corrigan received his Ph.D. in physics from the University of Colorado in 1968. After spending several years in academic physics, he joined Texaco Inc. in 1974 and worked on a variety of areas in seismic data processing. Since 1979, he has been working at the ARCO Exploration Research Department where he is presently a senior research advisor. The focus of his current activities is the application of multicomponent seismology to exploration geophysics.[1]

Awards

  • SEG Special Commendation 2016: Dennis Corrigan is awarded the Special Commendation for his contributions as a research leader in the 1980s at the ARCO geophysical research center in Plano, Texas. Corrigan had a profound positive impact as a collaborator and advisor to many ARCO geophysicists who have gone on to make significant professional contributions.[2]
  • Honorable Mention (Geophysics) 1990: B. S. Byun and D. Corrigan received 1990 Honorable Mention (Geophysics) for their paper Seismic traveltime inversion for transverse isotropy.[3]
  • SEG Special Commendation 2016: Dennis Corrigan is awarded the Special Commendation for his contributions as a research leader in the 1980s at the ARCO geophysical research center in Plano, Texas. Corrigan had a profound positive impact as a collaborator and advisor to many ARCO geophysicists who have gone on to make significant professional contributions.[4]

SEG Special Commendation 2016 [5]

Dennis Corrigan is awarded SEG Special Commendation for his contributions as a research leader in the 1980s at ARCO at the Plano Research Center in Plano, Texas. His research contributions include seismic source characterization, multicomponent seismic data, and VSP processing, and he was a pioneer in estimating anisotropic velocities from surface seismic data. Corrigan is an example of a creative force and pervasive mentor who was much better known to colleagues inside his corporate research organization than to external geophysicists. He had a profound positive impact as a collaborator and advisor to many ARCO geophysicists who have gone on to make significant professional contributions.

Biography Citation for the SEG Special Commendation 2016 [6]

By Jim Gaiser

Dennis Corrigan is a theoretical physicist with a strong mathematical background. He earned his bachelors degree (1964) and PhD (1968) from the University of Colorado (Boulder) in physics. His thesis, in the general field of elementary particle physics, dealt with investigating and modeling the electromagnetic interactions of baryons using dynamical group theory. Afterwards, he did three postdocs from 1968 to 1974 at UCLA, the University of Calgary, and the University of Utah where he continued his research in particle physics, and tutored students and other staff members at those institutions. Prior to joining Atlantic Richfield Company (ARCO), he worked at Texaco in Houston from 1974 to 1979, developing software for seismic processing applications.

At ARCO, Dennis was the principal research geophysicist in the Plano, Texas, research and technical center from 1979 to 1999. He was a creative force and pervasive mentor within ARCO and was the go-to person for colleagues inside the corporate research organization. He embodied the rare and optimal strengths that combined both theoretical insight and advanced programming skills to develop, test, and implement innovative seismic-processing solutions. Although he published and spoke only occasionally in public professional settings, his work was prolific. In addition, Dennis collaborated on numerous projects and was advisor, mentor, and tutor for many geophysicists.

His personal leadership inside ARCO’s research group was at such a high level that he was recognized with several “Outstanding Technical Achievement” awards throughout the years for a variety of signal processing technologies. Dennis received the award for f-x coherent noise attenuation filters (1987); was part of the team that developed the software to implement the inverse scattering theory version of surface-related multiple attenuation (1995); and was part of the team that developed acquisition and processing techniques for dual-sensor ocean-bottom cable data (1997). He led the industry in other areas of research that he conducted. For example, in the field of converted waves (PS-waves) he was the first to develop the correct expression for conversion-point location using vertical travel time and rms velocity, fifteen years before it was rediscovered in the late 1990s when PS-wave technology proliferated. Dennis also introduced an azimuthal velocity analysis for fracture mapping using 3D P-wave data with a rich distribution of source-receiver azimuths.

Dennis conducted his research by meticulously documenting the theoretical development of each project. When ARCO was purchased by BP, Dennis had compiled 17 research notebooks on numerous subjects: elastic wave equation and 3D Born modeling, nonhyperbolic moveout, modeling in azimuthally anisotropic media, reflection coefficients, inversion notes, elastic wave imaging and migration in anisotropic media, multiple theory, converted waves, and coherent noise attenuation. These read like textbooks and were impressively organized by section names and dates.

Dennis pursued his personal interests with the same enthusiasm and thoroughness as his geophysical research. Together with his lovely and gracious wife Phyllis, they would often entertain and prepare exquisite gourmet meals to the delight of many ARCO colleagues. He and Phyllis love to hike, garden, and enjoy bird watching. Their knowledge and observation of birds is on par with ornithologists. He is an avid reader of literature, poetry, and plays, and enjoys movies and theater. In his retirement, Dennis decided to learn more about cosmology. This too was approached with an intense study of the subject and has resulted in several notebooks of theoretical research.

It is my pleasure and distinct honor to write Dennis’ citation for this well-deserved award. Congratulations on your Special Commendation from the Society of Exploration Geophysicists, in recognition of your many remarkable contributions to developments in signal processing, analysis, imaging, and anisotropy.
