PDI and RPS have combined in a mutual effort to fully address the need for complete biostratigraphic data, particularly in USA Paleogene and Mesozoic age sections where integration of palynological data is critical to fully understanding the geohistory. PDI works closely with RPS staff in Houston and the UK for project development.  PDI staff can now fully complement RPS wellsite geologic services with coordinated data delivery and real-time operational assistance.
