Geogiga VSP 1.1 - Vertical Seismic Profiling SoftwareNew

Features | Screenshots | Version

Geogiga VSP can handle zero-offset and offset VSP survey. It utilizes F-K filter and median filter to separate downgoing and upgoing waves, and then deconvolves the upgoing waves by applying wavelet designed on downgoing waves, finally builds the corridor stack or VSP-CDP mapping.

Unlike the well velocity survey method, VSP records nearly all seismic waveforms instead of just first breaks. In the VSP survey, the receiver is located down the borehole and closer to the target so the accuracy is improved relative to the surface reflection measurement.

Main Features:

• Support zero-offfset and offset VSP survey
• Band-pass filter
• Gain control: AGC, trace balance, time variant scaling, etc.
• Static time shift
• Undo/Redo multi-step operations on seismic data
• Interactively pick first breaks with a trace magnifier
• Calculate interval velocity and average velocity
• Separate downgoing and upgoing waves with F-K filter and median filter
• Deconvolve upgoing waves by applying wavelet designed on downgoing waves
• Corridor mute
• Corridor stack
• VSP-CDP transform
