Phase Rotation - Overview

Apply phase corrections to individual seismic lines or to a seismic line within a fence. Cross-correlation diagnostics are available if the phase shift function is opened from a fence. View image

Using the Phase Rotation Function

1. Right-click on the seismic line you wish to phase rotate and select Phase Rotation or Tie with Diagnostics from the shortcut menu (or press <t> on your keyboard). The phase rotation function allows you to simply apply a phase correction to the seismic, while the tie with diagnostics function allows you to apply bulk shift, amplitude, polarity, and band-pass filter adjustments in the same window as the phase rotation. In order to use the phase corrections with diagnostics (cross-correlation analysis), you must open the phase rotation or tie with diagnostics function from a seismic line within a fence display.
2. Move the slider bars up and down to apply phase rotations. The seismic display will update dynamically.
3. Click <OK> to exit, and save the phase correction on the fly. Alternatively, click <Cancel> to exit without saving changes.

• Apply bulk shift corrections in the Phase Rotation window.
• Phase corrections will be displayed on the fly to the data by default.
