Biostratigraphy Services

PetroStrat provides a full suite of integrated biostratigraphic services (micropalaeontology, nannopalaeontology and palynology) to the Oil & Gas industry. We are specialists in the provision of wellsite (real-time) biostratigraphic services (>2,500 man days per annum) and high resolution, quantitative reservoir scale studies (either single well or multi-well). We are one of the largest providers of wellsite palynological services in the world.

PetroStrat Ltd has three scientific disciplines in our biostratigraphic team; micropaleontology, nannopaleontology and palynology. Learn more about these versatile fossil groups on these dedicated pages.

Truly global experience

• Unrivalled experience with 38 biostratigraphers (>470 man years).
• Core of PetroStrat’s biostratigraphers have >15 years’ experience in oil industry consulting (several ~30 years’ experience).
• All our biostratigraphers have a minimum M.Sc. in Micropalaeontology / Nannopalaeontology / Palynology and the large majority have 3+ years industry experience. Many have a specialist Ph.D.
• Well balanced staff portfolio. All newly qualified stratigraphers are entered into a full training program, with dedicated senior staff members.
• Our experience is global, but with an emphasis towards the Atlantic Margins – particularly NW Europe, North & West Africa, Latin America (including Venezuela, Brazil & Argentina), the Caribbean (including Trinidad), the Gulf of Mexico and the Canadian Atlantic Margin.
• Majority of scientific staff are fully certificated for offshore work, and are wellsite-experienced (many have conducted >50 wellsite assignments).

Methodology

• Quantitative analyses utilising well documented counting techniques (repeatable).
• Rigorous taxonomic principles applied.
• Distribution data are delivered in StrataBugs™ format.
• Zonations schemes – a combination of published, global, local and in-house zonations are utilised (and where possible tied to the Gradstein et al. schemes (2004, 2008, 2012). The in-house scheme is readily related to the sequence chronostratigraphic frameworks of Haq et al. (1987), Berggren et al. (1995) or Hardenbol et al. (1998).
• Palaeoenvironmental interpretations using a number of statistical methods and integration of micropalaeontology and palynology.
• Calibration to absolute ages where possible (TSCreator ™).
• Correlations and interpretations are available in ODM™ format, allowing integration with corporate databases such as OpenWorks™.
• Hard copy and digital (Acrobat pdf) report formats supplied as standard.

High resolution regional chronostratigraphic frameworks are essential for

• More accurate age determination by allowing first order correlation to first order stages.
• Identification of breaks in sedimentation/unconformities and calibration to the sequence stratigraphy.
• Basinwide stratigraphic correlation.
• Review and re-evaluation of vintage biostratigraphic data.
• Resolution of the relationship between lithostratigraphic units.
• A firm basis for dating seismic surfaces essential for regional correlation.
