What is being procured?

Scope of work

The primary objective of this VSP reprocessing work is to establish a consistently processed set of reference data to QC and verify seismic well ties in both time and depth.

Combining borehole seismic and well logging data with lessons learned from ongoing surface seismic reprocessing allows a comprehensive 3-way seismic to well tie analysis, with a focus on using one consistent workflow for all VSP and log datasets, with a well-defined seismic reference datum (SRD) and statics solution, in order to obtain a consistent VSP and synthetic seismogram reference dataset
