Service: Offset VSP

Both 2D and 3D VSPs improve reservoir characterization. High-resolution VSP data can be integrated with surface seismic data to provide detailed descriptions of formation properties and identification of reservoir compartments not possible with surface seismic data alone.

Benefits and Applications
Reservoir Delineation

• Depth prediction of seismic events ahead of and offset from the drill bit

• Time-depth correlation with surface seismic data

• Structural imaging

• Improves reservoir characterization by delineation of faults and pinchouts

2D VSP Imaging

• Improved vertical and lateral resolution compared to surface seismic

• Phase determination and matching of surface seismic

• Extraction of parameters for enhanced surface seismic processing

• Generation of a high-resolution velocity model at the wellbore

• Q compensation derived from borehole VSP data improves surface seismic resolution

The offset VSP provides enhanced resolution to the surface seismic data.

The offset VSP and Corridor Stack are superimposed on the surface seismic data.
