Biostratigraphy provides a valuable framework for understanding our planet’s complex history. It enables us to establish relative rock ages, reconstruct past environments and correlate formations (particularly useful in areas with poor seismic control and across basin margins). It is a fundamental tool in geological investigations for better understanding the subsurface and aiding in resource exploration.
PetroStrat has one of the largest teams of in-house specialist biostratigraphers in the world, with industry-leading and renowned experience and global knowledge spanning across all disciplines of micropalaeontology, nannopalaeontology and palynology.
Micropalaeontology
- Very abundant in marine deposits and certain non-marine sediments.
- Palaeozoic to Holocene
- Versatile tool to assess paleoenvironments and palaeobathymetry.
Palynology
- Abundant in a variety of environments, both terrestrial and marine.
- Pre-Cambrian to Holocene.
- We offer non-acid extraction, perfect for safe and environmental use at wellsite.
Nannopalaeontology
- Recent to Late Triassic (0 to 237Ma).
- Marine-only fossils.
- Quick and cost-effective preparations, even at wellsite.
This integration of all three fossil disciplines provides enhanced stratigraphic resolution at both reservoir and regional scale that is essential for accurate seismic interpretation, regional correlations, subsurface understanding and subsurface modelling.

Leaders in our field
Global experience
Bespoke services
Our goal is to support your sub-surface operations by delivering concise interpretations that provide valuable insights.
Why use biostratigraphy?
Our integrated biostratigraphy services deliver a high-resolution stratigraphic framework that can be used for:
- Calibrating seismic picks & providing stratigraphic control where seismic is poor.
- Interpreting paleoenvironments & understanding sediment provenance.
- Explaining the unexpected (e.g. faults, unconformities or facies change).
- Defining sequence stratigraphy.
- Real-time drilling/monitoring support and geo-steering.
With one of the largest teams of biostratigraphers in the world, we are perfectly equipped to cater to all your global biostratigraphic needs, from pre-drill and real-time drilling support at wellsite to routine post-well studies and large multiple well projects in our offices.
Pre-drill
Planning Phases
Our global experience and knowledge of taxa in basins across the world puts us in the perfect position to offer guidance and recommendations in the pre-drill planning phases.
Real-time drilling support at wellsite
With years of experience processing, identifying and interpreting data, we can provide safe, fast and accurate wellsite biostratigraphy services for supporting critical real-time decision making. This has proven success with significant savings on operational costs.
Routine post-well studies in our offices
Our internationally renowned laboratories and in-house team of experts provide detailed post-well analysis of samples, delivering a comprehensive report with quantifiable results that provide a high-resolution stratigraphic framework and feed directly into your subsurface model.
Wellsite Biostratigraphy
We specialise in the provision of wellsite (real-time) biostratigraphic services and are one of the largest providers of wellsite palynological services in the world. All three fossil disciplines can be applied at wellsite to provide real-time subsurface navigation and maximise operational efficiency.
Learn More about biostratigraphy and the three disaplines
What is Biostratigraphy?
Biostratigraphy uses fossil assemblages within sedimentary rock layers to establish relative ages and correlations between rock successions.
What is Micropalaeontology?
Micropalaeontology is a discipline of palaeontology mainly concerned with foraminifera, ostracoda, radiolaria and diatoms.
What is Nannopalaeontology?
Nannopalaeontology is the study of minute calcareous fossils, extracted from fine-grained sedimentary rocks.
What is Palynology?
Palynology is a scientific discipline concerned with the study of organic-bodied microscopic organisms, in both living and fossil form.
