Converted Wave Receiver Statics from First Break Mode Conversions

Summary The estimation of good quality receiver statics solutions for converted wave data is often problematic. This work applies a technique which uses P-to-S conversions by a refracted P-wave to derive the S-wave receiver statics. When a refracted P-wave converts to an S-wave at the base of the weathered layer both phases are recorded at surface. The arrival time difference between the two can be used to solve for statics. We estimate the converted wave static correction from receiver functions that are calculated by correlation or deconvolution of early arrivals like refracted energy on the vertical and radial component. This is demonstrated using synthetic and real data.
