Williston Basin TGI project logo


The TGI database comprises geological picks derived from most of the drillholes penetrating the Devonian and deeper horizons and from selected wells, averaging 5 wells per township in densely drilled areas, penetrating Mississippian- and Mesozoic-aged rocks. The final database contains information from a total of 7649 wells, which includes 5043 wells from Saskatchewan, and 2606 wells from Manitoba. These picks were used to create the geological maps, hydrogeological maps and model, and the 3-D basin model.

The database is available in both Access and Excel formats.

The Access version is a completely searchable database, allowing the user to view individual well information and formation tops, or do a customized search. The Access database can be downloaded here. Access 2003 runtime software is required to use the database.

The Excel version of the database has been broken down into three separate files, one for the Mesozoic data, one for the Mississippian and Devonian data, and one for the Lower Paleozoic (Silurian to Precambrian) data. The user is refered to the TGI Stratigraphic Column for a complete listing of formation/member names and correlations.

Miscellaneous Database Notes

  • Each well has a NAD 83 longitude and latitude. An accompanying UTM is also available, however please note that the UTM are in NAD 83, Zone 14.
  • All the picks shown in this database were verified and/or picked by the TGI project geologists.
  • The Source refers to the jurisdiction from which the wells originate:

    •  SK: Saskatchewan
    •  MOGWIS: Manitoba Oil and Gas Well Information System
    •  MSD: Manitoba Stratigraphic Database


The TGI team was dedicated to maintain accuracy and consistency in the picks and information presented, however due to the size of the project, some errors may have been missed. The TGI team is not liable for these errors. The user of this information accepts all responsibility for any work done on their part that uses all or part of this data.
