Borehole Seismic Calibration

The Value of Calibration

By correlating borehole seismic data measured in depth with your time-indexed surface seismic data, our specialists provide valuable information for 3D surface seismic migration, calibration of signal amplitudes and other seismic attributes, surface seismic inversion, and seismic reservoir characterization.

Schlumberger Data & Consulting Services (DCS) experts calibrate with borehole seismic results from multiple acquisition scenarios: checkshot (CSS), zero-offset (VSP-V), offset (VSP-O), and walkaway (VSP-W).

Seismic correlation

Correlating borehole seismic with surface seismic data begins with the expert acquisition, processing, and interpretation of data from checkshot surveys (CSS) and vertical seismic profiles (VSPs) of various kinds.

Velocities

Analysis of the velocity field in the vicinity of your wellbore or between wells provides essential information for 3D surface seismic migration.

Anisotropy

Direct measurement of vertical and horizontal anisotropy (VTI and HTI) values using effective and/or intrinsic methods can calibrate the velocity models required for 3D surface seismic migration.

AVO

Calibration of signal amplitudes or other seismic attributes also benefit amplitude versus offset (AVO) studies, surface seismic inversion, and seismic reservoir characterization.
