Geogiga VSP 1.0 - Vertical Seismic Profiling SoftwareNew

Features | Screenshots

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 deconvolve the upgoing waves by applying wavelet designed on downgoing waves, finally build the corridor stack or VSP-CDP mapping.

Unlike well velocity survey method, VSP records nearly all seismic waveforms instead of just the first break. In VSP survey, the receiver is located down the borehole and closer to the target so the accuracy is improved relative to 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 shifting
• Undo/Redo multi-step operations on seismic data
• Interactively pick the first break
• Velocity analysis, calculate interval velocity and average velocity
• Separate downgoing and upgoing wave with F-K filter and median filter
• Deconvolve upgoing waves by applying wavelet designed on downgoing waves
• Corridor mute
• Corridor stack
• VSP-CDP mapping
