Abstract: A digital grid of the top of the Empress Formation where present, or the topography of the surrounding landscape, where the formation is absent. This includes the units 1 to 3 of the Empress Formation in buried valleys, as well as undifferentiated Empress interfluve sediments resting on the bedrock surface between buried valleys. The unit is originally modelled from borehole data and adjusted to the bedrock surface, the surfaces of units 1, 2, 3 and interfluve units of the Empress Formation, and the present-day land surface. The grid is generated at a 250 metre cell-size resolution, based on 2003 information.

Abstract:
A digital grid of the top of the Empress Formation where present, or the topography of the surrounding
landscape, where the formation is absent. This includes the units 1 to 3 of the Empress Formation in buried
valleys, as well as undifferentiated Empress interfluve sediments resting on the bedrock surface between
buried valleys. The unit is originally modelled from borehole data and adjusted to the bedrock surface, the
surfaces of units 1, 2, 3 and interfluve units of the Empress Formation, and the present-day land surface.
The grid is generated at a 250 metre cell-size resolution, based on 2003 information.
Purpose:
To construct the geological framework in an area of Alberta that is undergoing rapid development of oil sands
deposits, for the purpose of characterizing the drift (Quaternary, pre-Quaternary) aquifers systems that
overlie oil sands deposits.

Evaluation method description:
All available data were used, and data were ranked in terms of source quality. All areas within the
geographic boundaries were modelled, but data density was not uniform throughout. Data were incomplete
or absent for the upper half of the geological strata that lay between the bedrock surface and the
present-day land surface because petrophysical logs were not recorded for the units behind the cased
interval in oil and gas wells, and other well data were too sparse.

Measure description:
In places where there were no data, or where data were absent, we assigned the value -999 to the grid cell
to denote null values in the modelled surface. In the case of the digital elevation model (DEM), which
was imported from other sources, the edges of the input grid were all null data (-999) to constrain the
geometry of the grid to reflect the NTS map boundary geometry. This geometry was propagated throughout
the grid surfaces by the assignment of -999 to ensure their edges conformed to the DEM geometry.
Stratigraphic pick data used to generate the surfaces were derived from a number of sources, including
new picks made during the course of the study. Because of varied degrees of certainty regarding the
quality of those data, all data were ranked in terms of quality, with the author's picks ranked highest.
This ranking was applied to screen data only in areas where more than one stratigraphic pick was made at
a given location. In those cases, the highest-ranked value was incorporated into the calculations. It is
important to note that all data were used in the process, and that in the absence of any other data,
lower quality data were used along with data of higher quality. Digital datasets in the model had a
varied degree of precision depending on the nature of the surface modelled. For example, the surface DEM
had the greatest precision as it was modelled from a 76-metre-grid-resolution source file, and it was
exposed and easily validated. Precision of the other surfaces varied according to data density and
knowledge regarding the processes of formation or deposition. Therefore, the modelled surfaces reflect
not only data density and quality, but also knowledge regarding the processes, which is depicted through
the addition of synthetic data, such as digital, hand-drawn contours. Consequently, grids of surfaces
with the least amount of knowledge or data were validated and constrained by surfaces that carried a
higher degree of confidence. Surfaces of geological units were tested against the two major
unconformities in the study area - the topography of the bedrock surface, which itself was tested
against the topography of the present-day land surface. This internal validation and testing was done
more rigorously for the bedrock topography and lower-drift stratigraphic units. This process produced
surface grids with geospatial integrity (that is, lower surfaces do not cross surfaces of higher units),
and enabled the construction of a bedrock subcrop map that was entirely constrained by the geometry of
the bedrock surface. Testing of geospatial integrity of the bedrock geology surfaces that lie beneath
the bedrock surface was not as rigorous, and in some cases, surfaces of lower bedrock units may cross
higher units. These occurrences, while present, are rare.

Description:
A series of digital grids were generated for surfaces of geological units ranging from the top of the
McMurray Formation to the present-day land surfaces. The grids were generated from hard data
consisting of stratigraphic picks made from geophysical logs and lithologs, as well as from
synthetic data consisting of digital hand-drawn contour lines, particularly for the bedrock
topography and the drift aquifer units resting on the bedrock surface. Initial digital modelling was
done using MCadContour software on an Apple Macintosh computer, which was later exported to
PC-supported software platforms, such as Viewlog (see Alberta Geological Survey Earth Sciences
Report 2002-03). All modelled surfaces were done on a 250 m grid-cell size, using Inverse Distance
Weighted interpolation method.
The bedrock geology units were modelled from stratigraphic picks derived from Alberta Energy and
Utilities Board databases. The bedrock topography and drift aquifer units were modelled from
stratigraphic picks made on resistivity and gamma logs derived mainly from oil and gas exploration.
Hand-digitized contours of the bedrock surface were used as synthetic data to enhance the resolution
of the modelled surface. All bedrock geology surfaces were tested against the bedrock topography (an
unconformable surface) to create a bedrock subcrop map. Gridded surfaces were then stacked in proper
stratigraphic order to generate a 2.5-D model of the geological setting.
