Borehole Seismic Imaging

3D/4D VSP

3D/4D VSP surveys are an affordable and timely solution for high resolution imaging around the wellbore. Compared to conventional 3D/4D surface seismic surveys, 3D/4D VSP's are inexpensive, can be completed in less time, and yield much higher image resolution.

3D VSP surveys provide high resolution three-dimensional imaging around the borehole. Repeat or time-lapse (4D) 3D VSP surveys are a powerful tool for reservoir surveillance over time.

Note: Typical geophone array for a 3D VSP ranges from 60 to 120 levels.
