Enhanced prestack depth imaging of wide-azimuth data

October 1, 2011
Xuening Ma, Bin Wang, Cristina Reta-Tang, Wilfred Whiteside, and Zhiming Li
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

October 1, 2011
Bin Wang, Jun Cai, Manhong Guo, Chuck Mason, Sampath Gajawada, and Duryodhan Epili
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

December 1, 2009
Shuqian Dong, Yi Luo, Xiang Xiao , Sergio Chávez-Pérez , and Gerard T. Schuster
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

December 1, 2009
Bin Wang, Chuck Mason, Manhong Guo, Huimin Guan, Kwangjin Yoon, and Zhiming Li
Subsalt wave-equation based migration (WEM) scan is an effective way for subsalt velocity updating, and has become an industry standard practice; however,.
