PS Converted-Wave Processing

Using 3C data acquired in the field, PS Converted-Wave Processing provides additional value to existing P-wave products. This includes shear-wave splitting analysis to detect localized fracture orientation and strength, and Γ (gamma) estimation, which is valuable in determining lithology and fluid content.
