Abstract
Use of the vertical seismic profile (VSP) as the link between surface seismic data and advanced log evaluations makes it possible to calibrate seismic sections in terms of subsurface petrophysical parameters.
A step-by-step procedure of (1) tying a surface seismic section to the borehole measurements via the VSP, (2)reprocessing the seismic section, and (3) propagating log information outward from the well using the calibrated seismic section is practical. In fact, if a VSP is run in the discovery well in a field, this procedure can be followed to obtain information about where to drill the first development well. If vertical seismic profiles are run in each subsequent development well, a continually updated reservoir description can be used to guide the development of the field.
