The seismic reflection image - stacking and velocities

Рет қаралды 10,054

Күн бұрын

Part of The Shear Zone channel. This video looks at how seismic images are made, displaying in two-way-time, enhancing signal to noise by stacking, and the impact of variations in seismic velocity on the image and its relationship to real subsurface geological structure. Most of the images are from the Virtual Seismic Atlas.

you saved my life! I was struggling so hard to understand how to read a seismogram! Thank you for your content

Really good treatment of this topic. I'm going to share this video with my Geophysics class right now! Thanks for sharing this.

Excellent discussion. I was a seismic data processor from 1973 to 2007. Experienced in dynamite, vibroseis, and airgun. I worked in various processing centers in the US, Australia, and Great Britain. I also worked quality control on both land and offshore seismic crews at various times. Your discussion is very good to inform the general public as to "what in the hell is all that noise and what are all of those wiggles?". Please keep it up!

what a beautiful clear voice and explanation! i wish i found this earlier as i've been struggling to let these little things click with me for weeks!!

Great video. I worked on land seismic crews in the seventies (surveying). I saw a lot of unprocessed sections in the field but only vaguely understood what I was looking at. Of course a lot this was done by hand back then and the technology has increased exponentially. (Incidentally I worked on what I was told was the first ever 3D seismic project ever. It was near Ardmore OK circa 1975. )

Great Course with excellent explanation Could you please recommend a text book to be read while following this course? Something suitable for undergraduates regards

@robbutler2095 2 жыл бұрын

Kearey, Brooks & Hill's book "Introduction to Geophysical Exploration" is very good place to start (and covers lots more than seismic). Mostly on the geophysical side - it does have some interpretation in it... otherwise for interp - try the numerous AAPG memoirs/course notes... these usually start fairly simply.... before ramping up the complexity. Happy hunting.

@@robbutler2095 Great, and I will recommend these videos for my students as a great reference for seismic interpretation course Are the slides of this course available online? I think it will be a great additive to the undergraduate,

@@MunirElmahdy Sorry - the slides aren't (most are animations anyway - BUT the seismic image examples and interpretations are pretty much all from the Virtual Seismic Atlas (seismicatlas.org) which is open access. Images are downloadable and free to use for teaching. It's still up and running as I write this....
