Biography for SEG Presidential Candidacy 2015 [1]

Bill Abriel was with Chevron for 36 years, beginning in New Orleans in 1978, and he retired in May 2015. His technical interests are in application of new technology to active projects, including acquisition, processing, interpretation, and integration. He was the geophysical lead for Chevron projects in many oil and gas basins around the world, concentrating on North America, China, Australia, South America, Russia, and Eurasia.

Abriel has participated in many technical committees for SEG meetings, has published in most industry journals, has been a member of the editorial board of The Leading Edge and an associate editor of Geophysics, and is an assistant editor of Interpretation. He was the SEG Spring Distinguished Lecturer in 2004 and the Distinguished Instructor in 2008.

Abriel is a founding board member of the research company SEG Advanced Modeling Corporation (SEAM) and is chair of its board. He was named a Life Member of SEG in 2007 and was SEG First Vice President in 2012. He also has served on numerous SEG committees, including Development and Production, Membership, Research, Global Affairs, and Distinguished Lecture.

Abriel received a B.S. in geosciences and an M.S. in geo- physics, both from Pennsylvania State University, where he was a founding member of the SEG Student Chapter and played four varsity years of lacrosse. He still keeps a hand in by coaching a local high school lacrosse team. He and his wife, Vangie, an attorney who teaches at Santa Clara University School of Law in California, have two children.

Position statement

SEG is an exceptional professional society that helps nurture all applied geophysics. I would like to give you my perspective on the near future of the organization. First, I think we must appreciate that applied geophysics includes exploration for petroleum and minerals as well as environmental and engineering problems and archaeology. Second, vital to the success of SEG is its business model — that of a cooperative of professional volunteers (us) working with resources coordinated from the SEG business offices.Our past has been strongly focused on geophysical theory, tools, and applications. But increasingly, our influence is becom- ing more integrated with the professions of geology and engi- neering in complex business decisions. Indications are that we can expect this trend to continue. So my sense is that it will be important to be proactive in some key areas: • Capital stewardship — SEG will likely face difficult economic challenges created by the oil and gas market changes this year. We will need to be sure that the investments and services of SEG are sustainable and of high value to the membership. • Member focus — SEG has an important opportunity to increasesupport and resources for the interpretation community, which comprises the majority of our membership. Initiatives such as the SEAM interpretation challenge, Haliburton’s EVOLVE, and Interpretation journal are all goods steps in that direction. • Intersociety initiatives — With increasing integration of geophysics with other professions, it must also be a priority to integrate SEG’s interests with those of other professional societies such as AAPG, SPE, SEPM, and EAGE. Much work is under way, and this needs to be both encouraged and improved.

William (Bill) Abriel is receiving Life Membership for his longstanding geophysical interests, achievements, advancements, and professional service. Bill started his geophysical career at Penn State University where he graduated twice, once with a B.S. in geosciences and once with an M.S. in geophysics. He also received four varsity letters in lacrosse.

Bill started working for Chevron in the U. S. Gulf Coast Division in New Orleans in 1978 and has continued with Chevron in various offices for the past 29 years. His technical interest has been in the application of new technology to live projects, and this has allowed him to be at the leading edge of acquisition, processing, interpretation, and also the integration of geophysics into the oil and gas business.

Bill has maintained a steady stream of publications and presentations explaining and advancing geophysical technology. I had the privilege of working with Bill on the early development of 3D interpretation techniques, and we were both very enthusiastic about the new level of geologic detail that can be extracted from 3D data. Bill and Roger Wright, Chevron?s first development geophysics manager, built a team of geophysicists that pushed 3D seismic data to the forefront of their company business. They managed the design, acquisition, processing, workstation interpretation, and geological analysis of the data for field delineation and developmin the Gulf of Mexico by significantly reducing dry holes and revealing new prospects.

Bill has also been involved in geophysical research, specifically the first Chevron applications of 3D DMO, 3D TI migration, 3D turning-wave migration, and 3D AVO. Bill was then the project technical lead for opening up the seismic subsalt play with applications of 3D prestack depth migration. He presented results at SEG?s 1999 Annual Meeting in which he showed the technique, application, and drilling success. Outside of the Gulf of Mexico, Bill has worked as the geophysical lead for Chevron projects in North America, China, Australia, South America, and Russia.

Bill started his professional society involvement as one of the founding members of the SEG student section at Penn State. Over the years, he has participated in many SEG meetings on a national, international, research, and multidisciplinary scale. He has continued to publish in most of the industry journals, and has served on the Editorial Board of THE LEADING EDGE and as an associate editor of GEOPHYSICS.

He has also participated in numerous committees including the development and production, membership, research, global affairs, and distinguished lecture committees. I have always found Bill?s technical opinions to be balanced, practical, and helpful.

Bill was the spring Distinguished Lecturer (DL) in 2004, and sought to extend the presentation internationally to help SEG with its global expansion. Now, in his position as the DL chairman, Bill is charged with arranging regional lectures on each continent. And Bill is the SEG/EAGE Distinguished Instructor for 2008 with the topic of reservoir geophysics.

Bill is most excited about the new SEG Advanced Modeling (SEAM) initiative. SEAM is designed to continuously identify the industry?s most interesting seismic problems in acquisition, processing, and interpretation, build and acquire numerical models, and then get the data into the public domain for common use. As one of the initiators of the program, and current member of the Board of Directors of the SEG Advanced Modeling Corporation, he has been thrilled to see the vision of this important program come to life.

It's not all geophysics in Bill's life. His wife Vangie is a talented attorney who teaches at Santa Clara University School of Law. He also takes pride in parenting his three children, and even gives a hand in coaching lacrosse.

Position Statement

It is my belief that we must be prepared for significant changes in both business drivers and technology transfer in the geophysics industry. The rapid growth of the emerged economies of Brazil, India and China will interact with the recent revolutions in Arabia. As a result, financial drivers for the geophysical industry will be unstable and we, the members of the SEG, have to be prepared for that change.

The strength of our SEG organization lies in the continued vision to be the primary geophysical forum for industry-related technology. We must protect and advance this against the disruptive forces of financial instability and the certain changes coming in the population of the SEG membership.

My vision for SEG is to:

  • Enhance the support for publications and meetings services for the membership.
  • Initiate and coordinate new, selective geophysical research cooperatives.
  • Reach the largest working population of geoscientists by establishing special partnerships with national oil companies.
  • Press the advance of global influence to make our society a world-connected institution.

I propose to advance these initiatives though service on the SEG Executive Committee. I hope I can count on your support.
