Geogiga VSP 7.0 - Vertical Seismic Profiling Software

Features | Screenshots | Version

Geogiga VSP can handle zero-offset and offset VSP survey. It utilizes F-K filter and median filter to separate upgoing and downgoing 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
• Frequency filter including Butterworth and Ormsby filters with the option of band pass, low pass, high pass, band reject, and notch
• Gain control: automatic gain control (AGC), trace balance, time variant scaling, single trace 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 upgoing and downgoing 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
