Gulf of Mexico
PetroStrat Inc is the leading American company that can analyze the entire stratigraphy of the GoM from Pleistocene to Jurassic, utilizing all three fossil groups (palynology, nannopaleontology & micropaleontology) to provide an integrated high resolution, 3-dimensional biostratigraphy.
Gulf of Mexico Wellsite Biostratigraphy
PetroStrat has unrivalled experience providing real-time and related post-well biostratigraphic services, with a long track record of successful projects where time critical drilling decisions are needed. We have more than 16 years of experience in providing real-time fully quantitative biostratigraphy in the GoM. Wellsite biostratigrapher teams are selected based upon relevant offshore area experience and discipline to provide an optimized cost-effective solution for each geological target.
Wilcox Formation (Palaeocene)
Utilizing a 3D biostratigraphic approach with the addition of palynology, this provides an up to 5-fold increase in stratigraphic resolution and has made us the market leader for Wilcox biostratigraphy. PetroStrat has developed a sequence stratigraphic scheme with over 20 lower order sequences now regionally mapped from the onshore Gulf Coast out into the deep water setting where low stand fan sand deposits provide the reservoirs for some of the biggest discoveries made in the US GoM in recent years.
Our experience includes:
- Over 100 analyzed well and outcrop sections
- Over 40 deepwater wells. Have undertaken real-time wellsite and post-well studies, including in the prolific Perdido area.
- Check out our STUDY pages for details of our regional studies, both available for licensing.:
Norphlet Formation (Mesozoic)
PetroStrat has analyzed a number of wells covering the Mesozoic section, including the deep Jurassic Norphlet target and the overlying Cretaceous formations.
Shallow and deepwater Miocene target reservoirs
PetroStrat employs Houston based nannopaleontologist and micropaleontologist staff with many years of experience in evaluating Miocene target reservoirs in both shallow and deepwater settings throughout the GoM region. Our senior micropalaeontologist is a world-class forams expert who has been on several recent deepwater successes.
Experience includes integrated palynology and micropaleontology services as well as review of vintage multi-well data sets.
North America Unconventionals
Besides providing integrated biostratigraphic services focused on event stratigraphy, we specialize in reservoir characterization using palynofacies. This is a powerful tool for evaluating paleoenvironments and source rock facies quality and potential. PetroStrat is the only American company which offers this service to their clients.
Our experience includes projects in:
- Permian Basin
- Eagle Ford
- Niobrara Duvernay Shale (Canada)
- Oil Sands (Canada)
Canada Atlantic Margins
We have completed 3 non-exclusive Stratigraphy studies on the Newfoundland margin: an Orphan Basin Study (10 wells), Flemish Pass Study (16 wells) and Carson Basin Study (9 wells). These are available via data licensing agreement. In addition, a fourth study focused on the Southern Flemish Pass (16 wells) is currently in progress. These studies apply a rationalised, robust, and high resolution biostratigraphic framework, based on full integration of all 3 biostratigraphic disciplines (micropalaeontology, nannopalaeontology & palynology). The more recent Carson Basin and Southern Flemish Pass studies are actually products of our joint venture Future Geoscience; these fully integrated studies also include chemostratigraphy, isotope stratigraphy and provenance investigations, applying the full stratigraphic tool-box!
In addition, we have provided wellsite biostratigraphy services on 3 deep-water exploration wells offshore Newfoundland (in the Orphan Basin and Laurentian Basin) and conducted full multidisciplinary post-well analyses on recent wells in the Flemish Pass. Elsewhere in Atlantic Canada a number of our senior staff have substantial experience on the Scotian Shelf, including a multi-well biostratigraphy review.
PetroStrat has industrial and academic experience associated with the Arctic Canadian area including the Beaufort Sea and Baffin Island areas. The latter area has included academic collaboration with CASP, using Devonian-Cretaceous micropalaeontology to integrate and calibrate with their macrofossil data.
PetroStrat has now gained significant experience in Mexico, in rocks of various ages, from the Tertiary Neogene down to the Jurassic.
Paleogene Perdido: PetroStrat has used high resolution biostratigraphy on both proprietary projects and an in-house multi-client study. This trend of wells continues southwest from the U.S.A. and PetroStrat’s experience there has proven to be applicable on the Mexico side of the border.
Onshore: PetroStrat has analysed numerous wells, focussing on the lowermost Cretaceous and Jurassic, in the Tampico Basin/Tuxpan Platform area, as well as Cretaceous intervals of wells in the Veracruz Basin.
Offshore, Sureste – Salinas Basins: This area has become a recent focus for PetroStrat, with the wellsite analysis of an increasing number of wells from several companies including wellsite monitoring on a significant discovery (Zama) and its appraisal wells. Wellsite micro- and nannofossil analysis has proved to be invaluable and PetroStrat has now provided wellsite biostratigraphy on seven wells offshore Mexico since 2018.
PetroStrat is also planning a non-proprietary, multiple- well Sureste Basin study comprising 15 wells.
