Abstract
An apparatus and method for processing a record of seismic traces. The method includes receiving the record of seismic traces in a time-offset domain, transforming the record of seismic traces to a tau-p domain, applying a zero offset inverse Q algorithm to the record of seismic traces in the tau-p domain, and transforming the record of seismic traces back to the time-offset domain.
Claims25
A method for processing a record of seismic traces, comprising:
- transforming the record of seismic traces to a constant angle domain such that each seismic trace corresponds to a constant angle, wherein the constant angle is defined as an angle between a ray path and a vertical axis at a surface;
- applying a zero offset inverse Q algorithm to the record of seismic traces in the constant angle domain;
- and
- saving the record of seismic traces to a storage device.
