The Society of Exploration Geophysicists (SEG) mourns the passing of Mike Graul, a distinguished geophysicist, educator, mentor, and longtime member of the Society since 1976.

Mike’s career spanned more than four decades and touched nearly every facet of geophysics. After graduating from Rensselaer Polytechnic Institute, he joined Chevron Corporation, where he worked for 23 years in acquisition, processing, interpretation, research, and project management. In parallel with his industry work, Mike demonstrated an enduring passion for education—founding Exploration Education Consultants in 1980 and later co-founding TexSeis, Inc., a seismic data processing company recognized for its technical rigor and practical innovation.

Above all, Mike was a teacher. He instructed thousands of geophysicists across more than 20 countries, teaching courses for SEG, AAPG, the University of Houston, and numerous in-company programs worldwide. His rare ability to explain complex concepts with clarity and humility left a lasting imprint on generations of practitioners.

“Mike was a giant in our profession,” said SEG President Joe Reilly. “His influence extended far beyond his own technical contributions—he shaped how we teach, learn, and lead within SEG.”

Mike’s service to SEG was both extensive and transformative. He became an SEG Foundation Trustee Associate in 1991 and served as an SEG Council Representative from 2000 to 2012, SEG First Vice President from 2010 to 2011, and later became SEG’s first Chair of the Council, serving in that role from 2012 to 2015. His leadership helped define the modern role of the Council within SEG governance.

In recognition of these contributions, Mike received numerous honors, including SEG Honorary Membership (2003), Special Commendation (1999), Life Membership (2019), and the SEG Council Medal (2024).

Past SEG Council Member Mark Bronston reflected, “To say Mike was a uniquely talented teacher and a wonderful human being is not an overstatement. He was a dear friend, a mentor, and someone whose guidance shaped my entire career.”

Those who knew Mike also remember his subtle humor, carefully chosen words, and deep generosity of spirit. As Allen Bertagne, longtime friend and recent Council Chair and Board Member, noted, “Behind Mike’s technical rigor was a mischievous wit and a genuine kindness that made working with him a joy.”

SEG extends its heartfelt condolences to Mike’s family, friends, and colleagues. His legacy lives on through the countless professionals he taught, mentored, and inspired.
