Abstract: A digital grid of the subcrop edge of the Base of Fish Scales horizon, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present (denoted by the number '15'), or where it is absent (denoted by the null value '-9999'). The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.

Abstract:
A digital grid of the subcrop edge of the Base of Fish Scales horizon, originally modeled from borehole data
and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit
is present (denoted by the number '15'), or where it is absent (denoted by the null value '-9999'). The grid
is generated at a 250 m cell-size resolution, based on information as recent as 2003.
Purpose:
To construct the geological framework in an area of the province that is undergoing rapid development of
oilsands deposits, for the purpose of characterizing the drift (Quaternary, preQuaternary) aquifers systems
that overlie oilsands deposits.

Evaluation method description:
All available data were used, and data were ranked in terms of quality of source. All areas within the
geographic boundaries were modeled, but data density was not uniform throughout. Data were incomplete or
absent for the upper half of the geological strata the lie 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 those places where there are no data, or where data are absent, the value '-999' is assigned to the
grid cell to denote null values in the modeled surface. In the case of the Digital Elevation Model,
which was imported from other sources, the edges of the input grid are all null data (-999) to constrain
the geometry of the grid to reflect the NTS map boundary geometry. This geometry was propagated
throughout all of the grids surfaces by the assignment of '-999' to ensure their edges conform 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's important to note that all data were used in process, and that in the absence of any
other data, lower quality data were used along with data of higher quality. Digital data sets in the
model have a varied degree of precision depending on the nature of the surface modeled. For example, the
surface DEM carries the greatest amount of precision as is it modeled from a 76m-grid-resolution source
file, and it is exposed and can be easily validated. Precision of the other surfaces varies in
accordance to data density and knowledge regarding the processes of formation or deposition. Therefore
the modeled surfaces reflect not only data density and data 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 carry 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 produces grids of surfaces that have geospatial integrity (that is, lower surfaces
do not cross surfaces of higher units), and enables the construction of bedrock subcrop map that is
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 lands surface. 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 contours lines, particularly for the bedrock
topography and the drift aquifer units resting on the bedrock surface. Initial digital modeling was
done using MCadContour software on a Apple Macintosh computer, which were later exporting to PC
supported software platforms such as Viewlog (ESR 2002-03). All modeled surfaces were done on a 250m
grid-cell size, using Inverse Distance Weighted interpolation method.
The bedrock geology units were modeled from stratigraphic picks derived from Alberta Energy and
Utilities Board databases (AGSWDB). The bedrock topography and drift aquifer units were modeled 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 modeled surface. All bedrock geology surfaces were tested against the bedrock topography (an
unconformable surface) to create a bedrock subcrop map. Gridded surfaces are then stacked in proper
stratigraphic order to generate a 2.5D model of the geological setting.
