Rock Flow Dynamics at EAGE Annual 2025 in Toulouse!

2nd June, 2025 We’re excited to announce that Rock Flow Dynamics will be exhibiting at the EAGE Annual Conference & Exhibition 2025, taking place from 2nd–5th June in the beautiful city of Toulouse,...

“I found the course to be very instructive, highly useful and well supported. Given the limited time available, a considerable amount of information was imparted, which did give it the feel of drinking from the fire hydrant of, rather than the well of, knowledge. However, that was to be expected.
All presenters were engaging and welcoming of discussion and questions. I came away with a much sounder grasp of geostatistical techniques, how to use these to interrogate my data, which are better in which situation, and how to do so in tNav. Finally, I would like to thank RFD for organising this course. Having access to world-class knowledge is a luxury and a real benefit. Along with the Tech Summit, it was a fascinating week of what can be done in tNav”.
