Abstract

Guided-waves have been clearly identified from crosshole datasets at the Conoco Borehole Test Facility (CBTF) by analysing their amplitude distributions, dispension characteristics, and 3-D polaraization diagrams. Such guided-waves have dominant energy in the seismograms. Our study also shows that almost any plane interface, or combination of interfaces will support the propagation of guided-waves in crosshole surveys, if approriate source signals can be excited at appropriate depths. We suggest that guided-waves have two potential applications in sedimentary reservoir seismics: continuity test for the reservoir layer(s) between boreholes; and monitoring Enhanced Oil Recovery (EOR) operations in thin-layered reservoirs by crosshole surveys.
