Birefringence study on 3-C/2-D: Barinas Basin (Venezuela)
P-SV data from the Barinas Basin (Venezuela) was processed with the goal of estimating the birefringence effect caused by an anisotropic layer. The target zone is a fractured carbonate reservoir at 3,000 m located in southwestern Venezuela. The time-lag between fast and slow S-waves (S-waves splitting), and the angle between line azimuth and orientation of the natural coordinates are determined using the Harrison rotation method based upon a modeling of the crosscorrelation function between rotated radial and transverse field components. Due to the small statics observed on the brute stacks of radial and transverse components, the time-shift could be associated with splitting effects due to the carbonate reservoir in this area.
