Pre-stack Interpretation

Interpret pre-stack data in a post-stack environment.

Often lost in the stacking process, pre-stack data carries useful information that can influence structural interpretations and lithology predictions made by geoscientists. Paradigm® SeisEarth® makes pre-stack data available to the interpreter by supporting the simultaneous display and interpretation of pre-stack and post-stack seismic data in a shared 3D visualization environment.

Pre-stack visualization is supported by flexible data loading capabilities, with no need to reformat or replicate data, so that even very large datasets can be efficiently viewed and interpreted.

Prestack interpretation benefits

Pre-stack and post-stack data in integrated display in SeisEarth 3D Canvas
 
  • With a common data format for pre-and post-stack seismic data, coupled with on-the-fly conversion of trace files to efficient brick structures for data roaming, Paradigm has overcome the traditional barriers associated with the use of pre-stack data in an interpretation and analysis environment
  • Quickly and easily validates pre- and post-stack seismic data received from seismic contractors
  • Pre-stack data supports qualification of reflector type (primary and multiple)
  • Pre-stack data supports qualification of lithology predictions (e.g. AVO/AVA anomalies).
  • A full set of visualization techniques applied to pre-stack data enhances QC and optimizes processing parameters
  • One common canvas for all interpretation objects enables geoscientists to share views, extend knowledge and exploit the information contained in pre-stack data
