“…To date, very few anisotropic model data sets have been publicly released. One anisotropic model, which is meant to investigate the behavior of seismic waves around a thrusted shale layer (as encountered frequently in the Canadian Foothills), has appeared both as a physical model data set (Leslie and Lawton, 1998) and a F-D synthetic data set (Fei et al, 1998). Figure 4 shows images of the synthetic data set migrated using isotropic and anisotropic migration algorithms.…”

“…In this paper, we modify the space‐time domain CFP analysis of Kabir (1997) to estimate anisotropic parameters for weak transverse isotropy media, and we use the Canadian Foothills model as an example. This model draws inspiration from the geology encountered in the Canadian foothills, where exploration targets often lie below a thrusted shale layer (Leslie and Lawton 1998; Fei et al . 1998).…”

“…Current anisotropic depth migration algorithms also correct for velocity changing with direction in the dipping clastic overburden-particularly in the case where the clastic overburden and the target reflectors have different dips. Several papers over the past seven years illustrate the improvements in imaging when we stop ignoring anisotropy and begin to correct for it (Ball, 1995;Vestrum and Muenzer, 1997;Vestrum, et al, 1998;Ferguson and Margrave, 1998;Schmid et al, 1998;Dai et al, 1998;Fei et al, 1998;Vestrum et al, 1999, Kirtland Grech et al, 2001etc. ).…”
