We extend the seismological receiver function method to the exploration
seismic domain to solve the problem of shear wave statics for multicomponent
data. The method relies on cross-correlation or deconvolution of
pressure with radial component traces in the common-receiver domain
followed by a stacking step. This procedure is repeated for each
receiver, resulting in a profile of high-resolution stacked receiver
functions; events corresponding to shallow mode-converted waves constrain
the shear wave static. The method is applied to a line of commercial
multicomponent seabed seismic data and gives results in good agreement
with a conventional statics method, although results along some other
lines require additional interpretation. In contrast to seismological
receiver function analysis, the main converted wave energy in the
receiver functions originates from reflection at shallow interfaces
rather than conversion of upgoing wavefields.
