Abstract
Method for inverting seismic data to obtain reflection properties by estimating or measuring (301) the source signature for the seismic data, then inverting (302) simultaneously for subsurface formation properties or reflection properties and for the amplitude attenuation and velocity dispersion effects integrated over the raypath from the source to the reflectors and to the receiver.
Claims13
A computer-implemented method for inverting seismic data to obtain reflection properties of a subsurface region, comprising:
- estimating or measuring a source signature for the seismic data;
- and
- using the source signature, inverting the seismic data simultaneously for a subsurface formation or reflection property and for amplitude attenuation or velocity dispersion effects or both, integrated over a ray-path from source to reflectors and to a receiver;
- wherein, at least the inversion is performed using a computer, and the inversion transforms the seismic data into an interpretable model of the subsurface region.
