Cross-well seismic data often contain strong tube waves and tube-wave-related arrivals due to the effects of the presence of two boreholes. A basic requirement for accurate cross-well seismic modeling and data processing is inclusion of these events. We use a 2-D velocity-stress variable-grid finite-difference parallel code for efficient cross-well field data modeling with inclusion of the two perforated cased boreholes. The synthetics resemble the field observations in terms of arrival times not only on P- and S-waves but also on tube waves and tube-wave-related secondary arrivals generated by perforations in the receiver and source wells. This study demonstrates that including boreholes into the modeling scheme can distinguish tube-wave-related events on seismograms to better assist data analysis and to guide data processing and interpretation.
