Cracked reservoirs are increasingly important as more exploration focusses on unconventional resources. Cracks are known to change the velocities of P- and S-waves, and these changes are known to be a function of crack width and orientation. Sensing that the P-wavespeed is changed due to cracks is difficult because many other parameters affect the wavespeed. We model how nonlinear wave interactions can be used to separate the effects of cracks. Specifically, we model how sensitive nonlinear wave interactions are to crack orientation with a particular focus on sets of randomly oriented cracks.
