dip dependent - meaning

Post by Tingpingbing »

Did someone here understand what "dip dependent" means?
On the equation below it says dip dependent?
Is this related to the structure or what?

And what is horizontal slowness?



M is the midpoint displacement with respect to the considered common midpoint position m0
x is the half source receiver offset
t0 is the zo two way traveltime
p horizontal slowness

Yes, dip relates to the structural dip of the events in this case the difference between the source-receiver midpoint and where the ray path from source to receiver reflects off the dipping layer. I would suggest drawing this to get your head around it (although there is an image on this blog page:

The seismic velocities are also a factor if the velocities are laterally varying. It's often convenient to work with slowness (that is to say 1/velocity ) rather than the actual velocity.

Loos like you are working towards DMO and PreSTM....
