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.
