Subsurface Stratigraphic Picks for the Top of the Oldman Formation (Base of Dinosaur Park Formation), Alberta Plains (tabular data, tab-delimited format, to accompany Open File Report 2011-13)

The dataset includes subsurface stratigraphic picks for the top of the Oldman Formation (base of the Dinosaur Park Formation) in the Alberta Plains (Townships 1 to 47, Ranges 1W4 to 5W5) made from wireline geophysical well logs. The dataset supplements Alberta Geological Survey Open File Report 2011-13, which describes the methodology used to make the picks. Well data were screened to detect errors resulting from deviated wells, as well as incorrect ground and kelly bushing elevation data. We used statistical methods to identify local and regional statistical outliers, which we examined individually.
