Abstract
Geophysical methods of prospecting for oil and gas resources are based on observations of elastic wave fields, treated to a first approximation as acoustic waves. Emitted pressure impulses penetrate the crust and then are backscattered to the surface where they are detected by an array of receivers. The goal of seismic processing is to recover from the recorded wave field as much information as possible about the earth subsurface.
Migration is an acoustic image reconstruction technique based on the inversion of the scalar wave equation. In the migration process the recorded pressure waves are used as initial conditions for a wave field governed by the scalar wave equation which propagates downward and in reverse time.
