[OpendTect_Users] OpendTect - creating a seafloor map by first breaks

[Steven Bottomley]

Fellow OpendTect users, 

 

I am a newbie user and very impressed with the functionality of OpendTect.

 

I am mapping an offshore area on a 3D survey with very rugose seafloor due
to recent channelling. I could create a water-bottom map using auto-track
but the channels are so steep that the auto-track search algorithm is pretty
unstable.

 

I am not familiar with the other facilities of OpendTect, but just wondering
if there is a workflow to pick first breaks on each trace and create a water
bottom map in that way.  The absolute value of water depth (TWT) is not
important, but picking a reasonably consistent event parallel to the water
bottom is.

 

Thanks for any suggestions and Happy Christmas!

 

Regards

 

Steven Bottomley
