Enhanced prestack depth imaging of wide-azimuth data

01 October 2011
We present a case study of enhanced imaging of wideazimuth data from the Gulf of Mexico utilizing recent technologies; and we discuss the resulting.

Postmigration multiple prediction and removal in the depth domain

01 October 2011
We have developed a new methodology for predicting and removing multiples in the postmigration depth domain based on wavefield extrapolation and.

Fast 3D target-oriented reverse-time datuming

01 December 2009
Imaging of subsalt sediments is a challenge for traditional migration methods such as Kirchhoff and one-way waveequation migration. Consequently, the more.

Subsalt velocity update and composite imaging using reverse-time-migration based delayed-imaging-time scan

01 December 2009
Subsalt wave-equation based migration (WEM) scan is an effective way for subsalt velocity updating, and has become an industry standard practice; however,.
