Although the Saskatchewan Ministry of Energy and Resources has exercised all reasonable care in the compilation, interpretation and production of this product, it is not possible to ensure total accuracy, and all persons who rely on the information contained herein do so at their own risk. The Ministry of Energy and Resources and the Government of Saskatchewan do not accept liability for any errors, omissions or inaccuracies that may be included in, or derived from, this product.

The map of subcropping Mississippian and Devonian strata has been generated using data modified from the Regional Stratigraphic Framework of Western Saskatchewan - Phase I (http://www.ptrc.ca/publications.php?f_action=news_detail&news_id=14022). The stratigraphic framework for these subcropping units is shown in the composite log (above). The composite log itself is a compilation of geophysical log traces from different stratigraphic units within multiple wells in west-central Saskatchewan.

Production data are provided by the Petroleum Statistics Branch, Saskatchewan Ministry of Energy and Resources, Petroleum and Natural Gas Division, and are current to 2010. Due to space constraints, only 46 oil and 25 gas fields in west-central Saskatchewan are numbered on this map sheet. Oil/gas pools from multiple producing zones within one field are not illustrated.

The authors thank the following people for their contributions to this map sheet: o Kim Heinemann as co-author of the Regional Stratigraphic Framework of Western Saskatchewan - Phase I o Tyler Music and Megan Love for GIS and other graphic contributions
