Found 10 records similar to Subsurface Stratigraphic Picks for the Belly River Group/Lea Park Formation Transition in East-Central Alberta (tabular data, tab delimited format)

Provincial

The dataset includes subsurface stratigraphic picks for the base of the Belly River Group/Wapiti Formation in the Alberta Plains (Townships 1 to 94, Ranges 1W4 to 14W6) made from wireline geophysical well logs. In general, the pick was made at the base of the lowest sandstone bed (overlying the Pakowki or Lea Park Formation) that was overlain by coal. If coal is absent, the pick was made at the base of the first sandstone. We screened the well data to detect errors resulting from deviated wells, as well as incorrect ground and kelly bushing elevation data.

The dataset includes subsurface stratigraphic picks for the top of the Foremost Formation (Belly River Group) in the Alberta Plains (Townships 1 to 52, Ranges 1W4 to 5W5) made from downhole wireline geophysical well logs. The top of the Foremost was picked at the base of a continuous sandstone or siltstone bed (low-gamma-ray) of variable thickness overlying the Taber coal zone. 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 were examined individually.

The dataset includes subsurface stratigraphic picks of the Milk River 'shoulder' in the Alberta Plains (Townships 1 to 73, Ranges 1W4 to 2W6) made from wireline geophysical well logs. The Milk River 'shoulder' is an informal term often used to refer to a distinctive 'shoulder' (deflection) on resistivity, sonic, density, and porosity logs. The Milk River 'shoulder' corresponds to the top of the Milk River Formation in southernmost Alberta, where it represents juxtaposition between paralic deposits of the underlying Deadhorse Coulee Member of the Milk River Formation and overlying marine shale of the Pakowki Formation. It is characterized by a leftward deflection (decreasing resistivity) upwards across the contact, forming the distinctive 'shoulder signature'.

The dataset includes subsurface stratigraphic picks of the top of the Belly River Group in the Alberta Plains (Townships 1 to 50, Ranges 1W4 to 2W5) made from wireline, geophysical well logs. The dataset supplements Alberta Geological Survey Open File Report 2010-10, which describes the methodology. We screened the well data 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 were examined individually.

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.

The dataset includes subsurface stratigraphic picks for the formations that comprise the Beaverhill Lake Group (Townships 29 to 113, Ranges 1W4 to 13W6) made from wireline geophysical well logs. The dataset also includes picks for the underlying Elk Point Group, and the overlying Woodbend Group. Lithostratigraphic picks for the Beaverhill Lake Group include the Fort Vermilion Formation, the Swan Hills Formation, the Slave Point Formation, and the Waterways Formation (top of the Beaverhill Lake Group). Lithostratigraphic picks for the underlying Elk Point Group include the Prairie Evaporite Formation, the Sulphur Point Formation, and the Watt Mountain Formation (base of the Beaverhill Lake Group).

The dataset includes subsurface stratigraphic picks of the tops of the Horseshoe Canyon/Wapiti and Battle formations in the west-central Alberta Plains (Townships 15 to 67, Ranges 16W4 to 3W6) made from wireline geophysical well logs. The dataset supplements Alberta Geological Survey Open File Report 2011-08, which describes the methodology. We screened the well data to detect errors resulting from deviated wells, as well as incorrect well-header ground and kelly bushing elevation data. Statistical methods identified local and regional statistical outliers, which were examined individually.

This dataset has stratigraphic and lithological picks of the upper bedrock and Quaternary geological units in the Athabasca Oil Sands Area extending north from Cold Lake to the Fort McMurray region. The picks were compiled from the mid-1970s to 2006 to construct maps of the subsurface distribution, structure, topography and thickness of near-surface bedrock and Quaternary stratigraphic units. Alberta Geological Survey staff, as well as staff from industry and other government departments, interpreted the data.
