Abstract

This report documents new subsurface stratigraphic picks released 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 using wireline geophysical well logs. The stratigraphic picks are published separately in Digital Dataset 2011-0006.

Representative wells illustrate the criteria used to make stratigraphic picks and highlight regional geological variability. Well data were screened to detect errors resulting from deviated wells or incorrect ground and kelly bushing elevation data. Statistical methods identified local and regional outliers. These were examined individually and either confirmed or removed from the dataset. A structure contour map for the top of the Oldman Formation is included to illustrate the regional structure in the southern Alberta Plains.
