Implementation of Kirchhoff prestack depth migration on GPU

17 September 2013
The massively parallel nature of Graphics Processing Units has made them an attractive platform for some computationally intensive algorithms. This.

Enhancement of seismic data quality and interpretation for mapping base Zubair sands of Southeast Kuwait

16 September 2013
The Lower Zubair sand reservoirs have produced or shown oil in several but not all of the wells drilled in western and southeastern Kuwait. Evidence from.

Broadband processing of linear streamer data

15 September 2013
Conventional marine seismic data is affected by the interference from ghosts on both the source and receiver sides. The natural diversity provided by.

Anisotropic model building with structurally constrained tomography inversion: A case study from the Angola Basin

14 September 2013
The Angola basin is characterized by steeply dipping sediments with rapid changes in dip direction particularly in mini-basins between salt bodies. This.

Angle domain illumination analysis along a target horizon

12 September 2013
We develop an efficient scheme of illumination analysis along a target horizon. With this scheme, we can calculate the Directional Illumination (DI) from.

A case study for salt model building using CFP full azimuth data

10 September 2013
We present a case study of the salt model building for a Gulf of Mexico area with a full azimuth (FAZ) dataset that was created by merging two orthogonal.

3D imaging from 2D seismic data, an enhanced methodology

08 September 2013
We have developed an enhanced methodology for creating a 3D seismic migration volume from a set of 2D seismic lines. The key challenge is to interpolate.

3C receiver orientation estimation by stack power optimization of reflected PS data

02 September 2013
In land multi-component (MC) data processing, the orientation of each receiver's horizontal components in the field (H1 and H2) is seldom known.

Shale gas reservoir characterization workflows

26 November 2012
As shale gas resources have emerged as a viable energy source, their characterization has gained significance. The organic content in these shales which.

Seismic attribute expression of differential compaction

25 November 2012
In a marine environment, topographic features on the sea floor will usually be covered by a thick layer of shale with the rise of sea level, resulting in.
