Update (March 2019): Almost 150 wells from the Perth Basin have now been added to our AUSTRALIS database!
MGPalaeo’s AUSTRALIS® geological database provides the most up-to-date interpretation of geological data that exists, covering more than 2000 wells across the North West Shelf and the Perth Basin using one consistent zonation scheme.
“An innovative stratigraphic database that gives the geoscientist the competitive advantage to identify new hydrocarbon accumulations and high grade prospective exploration acreage.” [Carnarvon Petroleum, 2016]
The AUSTRALIS geological database is available in its entirety or as data subsets that best fit your needs (i.e., a Vulcan Sub-basin pack, a Beagle & Bedout sub-basins Triassic pack, or even just as a single well). Contact us via Email ([email protected]) or Phone (08 9249 4628) and let us know your requirements.
And if you subscribe to the AUSTRALIS geological database, we will send you all the latest palynological data for wells across the North West Shelf as it becomes open file.
Every exploration well at your fingertips, available in an easy to use format and with all interpretations based upon the most up-to-date palynological data:
- biostratigraphy (reinterpreted/updated)
- standardized lithostratigraphy
- regional sequence stratigraphic framework
- wireline logs (edited and spliced)
- Geochemistry, checkshot survey, deviation data, casing points, cores, and more
The data for each well has also been independently tested through 2D and 3D seismic mapping by Carnarvon Petroleum geologists to ensure accuracy.
All new explorations wells will be added as soon as they become open-file.
This dynamic database is constantly being reviewed and updated as new data becomes available; each data point is checked by skilled geologists before being incorporated into the database. The incorporation of high resolution localized palynological events to improve well-to-well correlations is one such addition.
Central to our database, and one of its key advantages that separates it from all other databases, is the strength of the biostratigraphy, a cornerstone to any sound geological model. All palynological data has been reviewed and updated to one zonation scheme (the industry standard MGP 2014) by experienced palynologists. Such a consistent dataset is crucial when building geological models, providing greater confidence in lithostratigraphic and sequence stratigraphic picks, and correlations between wells.
All well data is currently available in simple data file format (i.e., .dat, .txt, .csv, .las), which can be easily imported into many software programs such as ODM/IC, Petrel, Kingdom, etc.
What makes the AUSTRALIS geological database unique?
Our experience and expertise provide a key point of difference to any other database incorporating palynological data. Knowing which palynological zonation scheme was originally used during the drilling of a well is incredibly important, because there have been several schemes used over time, each compiled by different palynologists and with substantial differences, some with details more restricted to certain fields. Understanding how these zonation schemes correlate or how different zones have evolved over time is crucial in providing a consistent dataset that can be used to underpin robust geological models.
Our highly experienced palynologists have reviewed and updated all available open file data, incorporating 35 years’ worth of MGPalaeo’s in-house interpretations. Ongoing research allows us to continue to make refinements to well correlations through the development of high-resolution event-based palynology. One of the key advantages is that we are able to review and infill palynological data so the database is constantly evolving.
Furthermore, our highly experienced sedimentologist has provided quality control on a regional basis, contributing what has been physically observed in cores and working closely with our palynologists to compile a consistent geological model. As more core is logged, this information is likewise carried over into the database to refine and improve the data (a core database is currently under construction).
Originally commissioned by Carnarvon Petroleum over a 12 month period between 2016-2017, this ground-breaking database was to provide the latest interpretation of all available open-file stratigraphical data from all exploration wells across the Carnarvon, Roebuck, Browse, and Bonaparte Basins.
Management at Carnarvon Petroleum saw the advantages the larger oil companies gained from a comprehensive well database. Having confidence in their well data, in particular the sequence and lithostratigraphic picks, meant they could move quickly on seismic interpretations while a good understanding of the regional geology helped to evaluate plays and prospects. As consultant biostratigraphers, MGPalaeo also saw the advantages of having our own database. This has allowed us to refine biostratigraphic zonations by understanding the impacts of facies, biostratigraphic surfaces of regional significance, and identify areas which would benefit from review and infill.
The database build involved reviewing all palynology data and standardising the biostratigraphy to the latest zonation scheme. Lithostratigraphic nomenclature has likewise been standardized for each basin, and with the aid of wireline logs, regional sequence stratigraphic picks have been made. All of the data has been thoroughly tested against seismic data by geologists at Carnarvon Petroleum.
Since these initial days, we have been expanding our database to encompass other basins across Australia and Papua New Guinea.
