This Open File contains the m/z 217, 259, 231, 177, 191 and 205 mass
chromatograms from gas chromatography-mass spectrometry (GC-MS) analysis
of saturate fractions of oil samples recovered during drillstem tests of
the Bakken Fomation (8 samples) and Madison Formation (76 samples) for
wells drilled in the southeastern Saskatchewan and southwestern Manitoba
part of the Williston Basin. A visual inspection of the mass chromatograms
reveals the distribution features of saturate biomarkers (e.g. steranes
and hopanes) in these Bakken and Madison oils. Geochemical and geological
interpretations based on these GC-MS results have been partially published
in journals and /or presented publicly ( References
