Common-azimuth migration of a North Sea dataset
نویسندگان
چکیده
3-D prestack common-azimuth depth migration has a strong potential for imaging accurately complex media and handling multi-pathing. We apply the technique to North Sea real data for imaging a salt dome. The results obtained demonstrate the efficiency of the method in complex media. A detailed analysis of common-image gathers shows opportunities for improving the velocity model.

متن کامل3D angle gathers from wave-equation extended images
We present a method to construct 3D angle gathers from extended images obtained using wave-equation migration. The method relies on an analytic formula that associates the reflection and azimuth angle to reflection kinematics in the images. The decomposition is able to render the angle gathers that characterize the reflectivity as a function of both reflection and azimuth angle simultaneously. ...
متن کاملShort Note Common-azimuth migration and Kirchhoff migration for 3-D prestack imaging: A comparison on North Sea data
Common-azimuth migration (CAM) is a 3-D prestack depth migration technique based on the wave equation (Biondi and Palacharla, 1996). It exploits the intrinsic narrow-azimuth nature of marine data to reduce its dimensionality and thus manages to cut the computational cost of 3-D imaging significantly enough to compete with Kirchhoff methods. Based on a recursive extrapolation of the recorded wav...
متن کامل3D North Sea case study of reconstruction
Irregularly and sparsely sampled seismic data that has been shot with a predominant azimuth for long offsets can be completely reconstructed. Our method uses reposting along receiver lines to exact crossline positions, followed by least squares reconstruction in the midpoint-offset domain. This reconstruction scheme has been applied to a 3D marine dataset from the North Sea. Various aspects and...
