SEG20 technical presentation: down/down deconvolution.

In a first for its 90 year history the SEG Annual Conference is now open as an all-virtual event. SEG20 is still bringing you the same cutting-edge technical content, but this year you can enjoy it from the comfort of your home or office.

We’re proud to be a platinum sponsor of the event, and to be featuring some of our latest results and new technologies in the technical programme.

Don’t miss Gary Hampson’s presentation titled “Down/down deconvolution”. You can catch it live on the SEG20 meeting platform at 2.15pm CDT on Tuesday October 13. Plus it will be available for viewing with your SEG registration any time until November 13.

A summary of Gary’s presentation, as described in the paper authored by Gary Hampson* and Greg Szumski, is as follows:

Up/down deconvolution is a very powerful OBN processing technique which, under the right circumstances, very effectively performs a combination of 3D signature deconvolution and free-surface multiple attenuation on the up-going wavefield. Using an adaption of the Delft feedback model, we introduce a new idea that we call down/down deconvolution.

Down/down deconvolution performs a combination of 3D signature deconvolution and free-surface multiple attenuation on the down-going wavefield. As a result, the down-going wavefield can be as effectively deconvolved as the up-going wavefield. This means that the additional shallow reflector coverage that results from down-going mirror-imaging can now be as effectively deconvolved as the more conventional up-going images. We demonstrate our new idea with an example from the North Sea.

A presentation not to be missed!
