There has been a continually expanding interest in wide azimuth (WAZ) data in all its variations. We are now challenged to take full advantage of the additional information available with minimal...

To identify and define a complex salt body with rugose top and base is essential in building an accurate velocity model for premium quality depth imaging. We present a few real data examples from...

We have developed a new methodology for predicting and removing multiples in the migration depth domain based on wavefield extrapolation and attribute based subtraction. The input for the prediction...

To attain the benefits of simultaneous shooting in marine data acquisition, either the simultaneous sources have to be placed far apart to minimize the interferences from one another or sufficient...

A constrained propeller ship noise removal technique for OBC data has been developed. The constraints include the ship lane information, global linear fitting to determine the ship movement, and the...

The conventional zero-lag crosscorrealtion imaging condition of reverse-time migration is subject to strong migration artifacts. This paper studies wavefield decomposition method under relatively...

Better de-multiple results are achieved by combining the strengths of SRME and wave field extrapolation techniques. In this paper, we illustrated three different techniques to attack this task. Among...

Wide-azimuth (WAZ) data is the most significant advance to have occurred in seismic acquisition and processing since the introduction of 3D seismic in the early 1980’s. Along with the promise of...

We present a case study of an anisotropic prestack depth migration (APSDM) project which used high-resolution, shallow tomography and anisotropic model building for a large depth migration project in...

The workflow for the practical application of the automated focusing analysis in time domain is demonstrated by deriving the TTI anisotropy parameters, epsilon and delta, from the previous VTI work...
