GST Technical Luncheon - Our speaker will be Dr. Marianne Rauch (TGS - Principal Technical Advisor). Meeting will be in-person at Baxter's InterUrban.
How AI derived sonic logs can improve the PSDM model building
Marianne Rauch*, Mike Perz, TGS
Abstract
Machine learning applications have started to infiltrate the geosciences especially in the fields of log estimations, interpretation of salt bodies and fault definitions, seismic processing such as automated first break picking and velocity analysis and pre-stack inversions for rock property estimations. Our industry is known for big datasets that are very suitable for this task.
We are showing an onshore example of how we utilize sonic logs that have been estimated through a gradient boosted trees machine learning process in our PSDM velocity modeling building and how we are benefitting from these additional data points.
Dr. Marianne Rauch – Principal Technical Advisor
PhD in Physics, 1985, Karl Franzens Universitaet, Graz, Austria
Marianne received her PhD in Physics in 1985 from Uni Graz in Austria. She started her oil career as research assistant at Curtin University in Perth, Australia more than30 years ago and has been active in geophysics ever since then. Marianne lived in many places and worked on-shore and off-shore basins all over the world. Her main specialties are DHI, seismic processing, depth migration, potential fields and researching new technologies, methodologies. She likes to do applied research, mentor and teach and is a seasoned presenter at conventions and workshop. She has published a good number of articles on several subjects and still is passionate about geoscience and the thrill to get more and unique information out of geophysical measurements that help drilling more successful wells. Currently, she is the Principal Technical Advisor, TGS, Houston.
