Prestack for InterpretersHeadwave’s Prestack for Interpreters is an integrated Windows/Linux software solution, giving easy access to potentially enormous prestack datasets from single PCs.
Overview Routine 3D visualization of prestack data can reduce turn-around time at all stages of a project’s lifecycle, from real-time visualization and analysis of shot gathers during acquisition, to true 3D QC of gathers during data processing (no more sparse sampling of gathers in 2D viewers!) -- to new insights into the quality of poststack datasets and horizons for interpreters and drilling decision makers.
Viewing Prestack GathersPrestack for Interpreters allows users to view any type of gather, (shot, receiver, cmp, etc.) as either a 3D volume in its own domain space, or, in the case of midpoint gathers, linked intuitively to either a corresponding poststack inline or crossline.

Panning through any axis in 3D prestack volumes

Automatically advance any axis through the volume
|
|
In either case, users have the ability to view either a single gather ‘slice’, or a volume of gathers which can ‘pan through’ along any axis (gather, offset or time, for ex.) |
Users also have the ability to change the transparency/opacity of a gather or gather volume.

Data ManagementData management of terabytes of prestack data is a non-trivial part of data processing and exploration & production. To counter the challenges of frequent, cumbersome transfers of huge datasets Headwave has introduced a unique compressed, multi-dimensional, multi-resolution dataformat. By compressing the original datasets in multiple dimensions, it is possible to reduce the size of the file(s) to a level where logistics is no longer a bottleneck to the use of prestack data.
All licensed users are provided with a conversion tool for converting SEG-Y into the Headwave format, which they are free to use and provide to their data processing partners. More information is available on the  Data Management pages.
