Subsections of Estimation
3d estimation
3d estimation performs parameter estimation using kriging and other methods to map 3D analytical data onto volumetric grids defined by the limits of the data set, or by the convex hull, rectilinear, or finite-difference grid extents of a geologic system modeled by gridding and horizons. The module provides several convenient options for pre- and post-processing input parameter values, and allows the user to consider anisotropy in the medium containing the property.
3d estimation also has the ability to create uniform fields, and allows the user to choose which data components to include in the output. Uniform fields require no geologic input and Adaptive Gridding must be turned off (otherwise the connectivity is not implicit).
The DrillGuide functionality produces a new input data file with a synthetic boring at the location of maximum uncertainty calculated from the previous kriging estimates, which can then be rerun to find the next area of highest uncertainty. There are no limits to the number of cycles that may be run.
Variogram Options:
There are three variogram options:
- Spherical: the default and recommended choice for most applications
- Exponential: generally gives similar results to Spherical and may be superior for some datasets
- Gaussian: notoriously unstable, but can “smooth” your data with an appropriate nugget. Without a nugget term, Gaussian is generally unusable. If Gaussian kriging is overshooting the plume in various directions, the nugget is likely too small; if the plume looks overly smooth, the nugget is likely too big.
The “Power Factor” is only used for exponential or Gaussian variograms. The default value of 3 is the most common value for exponential. For Gaussian, 2 is most common, though values from 0.1 to 3 are typically acceptable.
Advanced Variography Options:
3d estimation supports complex directional anisotropic variography. The variogram is displayed as an ellipsoid that can be distorted to represent primary and secondary anisotropies and rotated to represent heading, dip, and roll. Overall scale and translation are provided as visual aids to compare the variogram to the data, though these do not affect the actual variogram.

2d estimation
2d estimation performs parameter estimation using kriging and other methods to map 2D analytical data onto surface grids defined by the limits of the data set as rectilinear or convex hull extents of the input data.
Its Adaptive Gridding feature further subdivides individual elements to place a “kriged” node at the location of each input data sample. This guarantees that the output will accurately reflect the input at all measured locations (i.e. the maximum in the output will be the maximum of the input).
The DrillGuide functionality produces a new input data file with a synthetic boring at the location of maximum uncertainty calculated from the previous kriging estimates, which can then be rerun to find the next area of highest uncertainty. The naming of the “DrillGuide©” file which is created when 2d estimation is run with all types of analyte (e.g. chemistry) files ends in apdv1, apdv2, apdv3, etc. There are no limits to the number of cycles that may be run.
2d estimation also provides special data processing options that allow it to extract 2-dimensional data sets from input data files containing three-dimensional data, and allows detailed analyses of property characteristics along 2-dimensional planes through the data set. The module also provides options to magnify or distort the resulting grid by the kriged value of the property at each grid node, and allows automatic clamping of the data distribution along a boundary offset from the convex hull of the data domain.
Variogram Options:
There are three variogram options:
- Spherical: the default and recommended choice for most applications
- Exponential: generally gives similar results to Spherical and may be superior for some datasets
- Gaussian: notoriously unstable, but can “smooth” your data with an appropriate nugget. Without a nugget term, Gaussian is generally unusable. If you find that Gaussian kriging is overshooting the plume, your nugget is likely too small; if the plume looks overly smooth, your nugget is likely too big.

cross validation
The cross validation module evaluates the predictive accuracy of an interpolation model by systematically withholding subsets of the input data, re-running estimation on the remaining samples, and comparing the predicted values against the withheld actuals. Two methods are supported: K-Fold, which divides the data into K subsets that each take a turn as the validation set, and Leave One Out, which validates each individual sample or boring one at a time.
The module accepts interpolation options from an upstream estimation module and outputs a field containing the actual values, predicted values, and their differences. Summary statistics are displayed in the Properties panel after the run completes.

gridding and horizons
The gridding and horizons module uses data files containing geologic horizons or surfaces (usually .geo, .gmf, and other ctech formats) to model the surfaces bounding geologic layers that provide the framework for three-dimensional geologic modeling and parameter estimation. Conversion of scattered points to surfaces uses kriging (default), spline, IDW, or nearest neighbor algorithms.
gridding and horizons creates a 2D grid containing one or more elevations at each node. Each elevation represents a geologic surface at that point in space. The output can be sent to 3d estimation, horizons to 3d, horizons to 3d structured, surfaces from horizons, and other modules.
The module can produce layer surfaces within the convex hull of the data domain, within a rectilinear domain with equally spaced nodes, or within a rectilinear domain with specified cell sizes such as a finite-difference model grid. The finite-difference gridding capability allows the user to visually design a grid with variable spacing, then krige the geologic layer elevations directly to the finite-difference grid nodes.
gridding and horizons also has the ability to read .apdv, .aidv, and .pgf files to create a single geologic layer model. When such a file is read, the module interprets it as geology as follows: if top-of-boring elevations are provided, they define the ground surface; otherwise, the highest sample elevation in each boring is used. The bottom surface is created as a flat surface slightly below the lowest sample in the file.

analytical realization
The analytical realization module is one of three similar modules (the other two are lithologic realization and stratigraphic realization), which allows you to very quickly generate statistical realizations of your 2D and 3D kriged models based upon C Tech’s Proprietary Extended Gaussian Geostatistical Simulation (GGS) technology, which we refer to as Fast Geostatistical Realizations^®^ or FGR^®^. Our extensions to GGS allow you to:
- Create realizations very rapidly
- Exercise greater control over the frequency and magnitude of noise typical in GGS
- Control deviation magnitudes from the nominal kriged prediction based on a Min Max Confidence Equivalent
- Deviations are the absolute value of the changes to the analytical prediction (in user units)
- Apply Simple or Advanced Anisotropy control over 2D or 3D wavelengths
C Tech’s FGR^®^ creates more plausible cases (realizations) which allow the nominal concentrations to deviate from the peak of the bell curve (equal probability of being an under-prediction as an over-prediction) by the same user-defined confidence. FGR allows the deviations to be both positive (max) and negative (min), and to fluctuate in a more realistic randomized manner.

lithologic assessment
The lithologic assessment module evaluates the quality of a lithologic model on an individual material basis. It works by shifting the realization probabilities toward the minimum or maximum plume bounds for a selected material, producing an output field that reflects a conservative or aggressive interpretation of material extent.
The assessment procedure is:
- Select the material to be assessed.
- Choose a Min Max Confidence Equivalent value (e.g., 95%). A value of 50% produces results equivalent to the nominal kriged model; higher confidence values (90%+) show greater deviation from the nominal.
- Select the direction (Min or Max) to shift toward.
- Choose the nodal and cell data components to include in the output.

external kriging
The external kriging module allows users to perform estimation using grids created in EVS (with or without layers or lithology) in GeoEAS, which supports advanced variography and kriging techniques. Grids and data are exported from EVS in GeoEAS format, kriged externally, and the results can then be read back into EVS and treated as if they were kriged natively.
This is an advanced module intended for users with experience in GeoEAS and geostatistics. C Tech does not provide technical support for the use of GeoEAS.
The workflow has three stages: export the data (Export Data group), export the grid (Export Grid group), run the external kriging in GeoEAS, then import the results (Import Data group).
