Biostratigraphy uses microfossils to distinguish between layers of rock deposited at different geological time intervals. Biostrat JV expertise extend from the Paleozoic to Cenozoic, offering the most suitable biostratigraphers for even the most complex geological regions.
Purpose and Importance
- Monitor stratigraphic development of wells
- Determine casing points, coring sections or well TD
- improve seismic calibration real-time
- Steer horizontal wells while drilling to maintain position within a reservoir to maximize recovery
- Identify zones of borehole instability
- Monitor coring programs
- Real-time calibration and correlation of important seismic markers and regional sequence boundaries
Biostrat JV offers full 24-hour wellsite monitoring using two rotating biostratigraphers and certified technicians who prepare drill cuttings for observation of micro- and nannofossils. Wellsite biostratigraphy requires minimal processing equipment and no hazardous reagents.
A multidisciplinary approach may include any combination of the principle microfossil groups to attain the highest resolution and certainty in assigning biostratigraphic zones.
Micropaleontology
Paleozoic-Recent marine sediments
Foraminifera
Ostracods
Diatoms
Radiolaria
Nannopaleontology
Triassic - Recent marine sediments
Calcareous nannofossils, also known as coccoliths.
Palynology
Phanerozoic marine & non-marine sediments
Plant matter such as spores & pollen
Dinoflagellates
The microfossils trapped in rocks also provide details of the environmental conditions during sedimentation. Biostrat JV biostratigraphers have a minimum M.Sc. in relative paleontological fields and well established experience consulting in the Caribbean, Latin American and Gulf of Mexico regions. Biostrat JV methods are fully quantitative and allow for the most reproducible models of:
- Basin bathymetry & paleoshorelines
- Paleoclimate & oceanography
- Dissolved oxygen concentrations, salinity, pH & nutrient flux
Microfossil data is delivered in Stratabugs TM format and allows for the best:
- Recognition of regional sequence boundaries, systems tracts and maximum flooding surfaces
- Paleo-water depth and sediment distribution interpretation for each rock sequence
- Model basin eustasy to account for rates of sediment accommodation within the basin
- Identify exploration play fairways and connectivity
A multidisciplinary approach may include any combination of the principle microfossil groups to avoid barren intervals and attain the most information.

Biostrat JV uses macro and micro benthos to assess marine environments prior to and post drilling or construction activities. This is essential to attaining permits and meeting environmental requirements.
Biostrat JV in-house micropaleontologist has obtained a Ph.D. qualification in tropical foraminifera for biomonitoring. Biostrat JV has conducted extensive Environmental Baseline Surveys (EBS) offshore Trinidad and elsewhere in the Caribbean region. This database of species distributions is an indispensable resource for identifying persistent community changes related to human activity or long-term climate change.
Quantitative analyses of live and dead species are obtained via grab samples of seafloor sediment.
Live specimens are distinguished from dead specimens by using a protein stain, rose bengal, that stains the living cytoplasm pink.
Species presence and absence is determined by a unique range of tolerance for environmental factors such as temperature, pH, dissolved oxygen, food supply, water circulation, sedimentation and turbidity.
Foraminifera test deformities related to anthropogenic pollution
Quantitative sedimentary analysis provide details of the energy and chemical composition of the environment during deposition.
Microfossils are used to assess geohazards and determine the most stratigraphically sounds sites for rigs and other installations.
Site hazards include
- Heavily faulted areas
- Areas Prone to slumping
- Relatively young or unconsolidated sediments
- Mass movement processes
- Seismic agitation
- Liquefaction of rock layers
Microfossils will detect geological hazards and play an important role in avoiding exorbitant re-mobilization or re-instillation costs.
