PetroStrat has experience of providing integrated palynology and micropalaeontology of the Alaskan area including the analysis of one well and the review of vintage datasets.


Canada Atlantic Margins

There are three PetroStrat non-proprietary projects for offshore Newfoundland, two of which are complete, with the third ongoing. These are the Orphan Basin Study, Flemish Pass Study and Carson Basin Study; these are focussed on the Cretaceous and Jurassic, primarily using nannofossil analyses, but also including micropalaeontology and palynology.

In addition, many PetroStrat staff members have extensive experience of the Atlantic Canadian offshore regions including Newfoundland, Nova Scotia and Grand Banks. This has involved multi-well review of vintage data and integration with new analyses for all disciplines (Tertiary – Jurassic). Additional experience has been to provide wellsite biostratigraphy on several deeper water wells offshore Newfoundland.

Arctic Canada

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.


Gulf of Mexico

PetroStrat has extensive experience in the Gulf of Mexico, using high resolution palynology on both proprietary projects and in-house non-proprietary studies. The two non-proprietary studies: Palynological Study of the Lower Tertiary Wilcox Group in Selected Deepwater Wells and Lower Paleogene Onshore Study, Gulf of Mexico, together provide a detailed biostratigraphic / sequence stratigraphic framework for the Paleocene-Eocene succession, which can then be applied to the analysis of further proprietary well sections, both as post-well projects and at the wellsite. More than 70 Wilcox well sections have now been analysed, including numerous wells from the prolific Perdido area.

PetroStrat also has significant experience in the analysis of the younger, Miocene reservoir, including providing wellsite biostratigraphy using integrated micro- and nannopalaeontology. In addition, PetroStrat has analysed a number of deeper Norphlet target wells, in some cases analysing from the Neogene to the Jurassic.

North America Unconventionals

We have gained particular experience providing integrated biostratigraphy for a variety of unconventional reservoirs and sources including the Oil Sands and Duvernay Shale from Canada and the Marcellus Shale and Eagleford Formation from the USA. This has included 13 wells from the Eagle Ford Shale, 5 from the Permian Basin, 3 wells from the Cuervo Hills Pennsylvanian Fm, 2 wells from Colorado (Dry Sage and Harper Hill) and 3 wells from Alberta, Canada.


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.
