Biography for 2015-2016 SEG Director at Large

Maurice Nessim is the president of Schlumberger PetroTechnical Services, based in Houston, Texas.[1] His responsibilities include the management of processing, interpretation, and integration of all E&P information from seismic to production, as well as expert consulting services for reservoir characterization, field-development planning, production enhancement, and oil and gas training and development.

Nessim has more than 30 years of oil and gas industry experience in various management and technical positions. He started his career at Schlumberger in Cairo as a geophysicist. After multiple roles in this domain, he progressed to chief area geophysicist of the Middle East and Africa. In the past 15 years, Nessim has held several senior positions at WesternGeco as vice president for Middle East, Africa, and Asia, vice president for North America, and global vice president of operations. He has a bachelor’s and master’s degree in physics and geophysics. His technical interests include the extension of geophysical application to other domains such as drilling and production.

Nessim’s most fulfilling moment in his career was creating and teaching an advanced applied geophysics program for Cairo University master’s degree graduates to gain exposure to geophysics in the oil and gas industry. He is proud to have created a significant impact in their future growth as professionals. Many of these graduates are now industry-recognized geophysicists who participate in SEG. Nessim cofounded the SEA Egypt Foundation, which focused on creating awareness about pollution in the Red Sea and hosted opportunities for environmental cleanup. He has won several awards, including the Schlumberger Chairman’s Award in 2006. He is author or coauthor of more than 25 papers presented at international conferences, including EAGE, SEG, SPE, and AAPG. He has been an SEG Active Member since 1991 and is a member of EAGE, SPE, and AAPG.

Position Statement

I strongly believe that SEG should empower geophysicists from around the world while promoting a career in geophysics to a younger demographic. I hope that my leadership skills, geophysical expertise, and international experience will help to strengthen the decision quality of the Board and contribute to SEG’s direction. I am honored to be nominated for a Director-at-large position on the Board. If elected, I will strive to:

  • implement a “Geophysics Beyond Exploration” program, aiming to take geophysics beyond a technical point of view to impact the oil and gas industry. This program will focus on the integration of all geophysical disciplines to make geophysics more relevant to all upstream industry professionals.
  • create a “Day in the Life of a Geophysicist” program to help young professionals in the oil and gas industry expand their careers and look toward geophysics as the number-one career choice. This program will focus on making geophysics more attractive to a younger population and will discuss the continuous challenges and perpetual education offered in the life of a geophysicist.
  • expand awareness of SEG and use its educational activities to underrepresented populations and be the voice of their challenge.
