TECHNICAL PROGRAM INFORMATION

The 2018 Technical Program features more than 1,080 quality presentations in 151 diverse sessions, including 10 special sessions and one special global session.

Geoscience professionals from all geophysical disciplines and all parts of the world are represented and will share the latest case histories, technological advancements, and research discoveries.

The Technical Program will begin on Monday at 1:50 PM, following the SEG Opening Session and Presidential Address. Oral sessions and poster sessions will run through Thursday at noon. Immediately following, postconvention workshops will take place in the technical session area on Thursday afternoon and all day Friday.

SPECIAL SESSIONSThese dedicated sessions will be offered to complement the technical program:

• Recent Advances and the Road Ahead

• Developments and Applications of Surface-Wave Methods

• Engineering Geophysics

• Geophysics and Medical Imaging Applications

• Geophysicists in the Workforce

• California Case Studies

• SEG/AGU Hydrogeophysics

• VSP, Advanced Processing, and Imaging Approaches for DAS

• Injection Induced Seismicity

• Novel DAS Sensing Strategies and Machine Learning

SPECIAL GLOBAL SESSION• Southern Gulf of Mexico and Latin America

NEW THIS YEARA new hot Technical Program topic for SEG18, Machine Learning and Data Analytics for E&P, will be highlighted with sessions on:

• Classification for Interpretation

Uses of the Machine Learning approach for automatic interpretation or as an aid to interpretation of geological features such as faults, horizons, and salt bodies

• Noise Attenuation and Seismic Processing

Machine Learning methods used for noise attenuation or suppression, and seismic processing

• Facies Classification and Reservoir Properties
