Our work


Biostratigraphy is the study of the spatial and temporal distribution of fossil organisms and serves as a means for dating rocks and sediments. Over the past thirty years, TNO has gained ample experience in the application of biostratigraphy for the oil and gas industry. Although palynology and micropaleontology are primarily used for the correlation of strata, new and innovative tools such as phytoliths are being developed.

Despite the use of geological models and 3D seismics in the exploration and production of oil and gas, biostratigraphic control is still necessary. The biostratigraphic expertise of TNO enables oil companies to fine-tune their geological models with accurate age and paleoenvironmental data.

TNO has developed a number of innovative tools that demonstrably improve the effectiveness of biostratigraphy in hydrocarbon exploration. The Palynomorph EcoGroup (PEG) model and the Automated Palynodebris Analysis (APA) technique have been developed to recognize subtle but synchronous paleoenvironmental changes that would otherwise remain unnoticed. Both these tools have been successfully employed for various customers. Another challenging project is the development of a phytolith-based stratigraphy for the Rotliegend deposits of the North Sea region.
