Since 1930, the Society of Exploration Geophysicists (SEG) has advanced the science and application of geophysics—connecting professionals, fostering innovation, and building a global community united by curiosity and purpose.
What began as a small group of pioneering explorers has evolved into a worldwide society of scientists and engineers driving progress in energy, environment, and emerging technologies. SEG’s history is one of collaboration—linking academia, industry, and government to solve complex challenges through applied geophysics.
