We have developed a new methodology for predicting and removing multiples in the postmigration depth domain based on wavefield extrapolation and attribute-based subtraction. The inputs for the...
Imaging of subsalt sediments is a challenge for traditional migration methods such as Kirchhoff and one-way waveequation migration. Consequently, the more accurate twoway method of reverse-time...
Subsalt wave-equation based migration (WEM) scan is an effective way for subsalt velocity updating, and has become an industry standard practice; however, the cost of generating migration scan is...
