The stratigraphic realization module is one of three similar modules (the other two are analytical realization and lithologic realization), which allows you to very quickly generate statistical realizations of your stratigraphic horizons based upon C Tech’s Proprietary Extended Gaussian Geostatistical Simulation (GGS), which we refer to as Fast Geostatistical Realizations^®^ or FGR^®^. Our extensions to GGS allow you to:
Create realizations 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 surface elevations for each stratigraphic horizon
Apply Simple or Advanced Anisotropy control over 2D wavelengths
For stratigraphic realizations only: Natural Neighbor interpolation is supported in addition to kriging for the input model.

Description
Input
Stratigraphic Grid Data
Realization
Information required for direct exporting of stratigraphic grid data.
Output
Output Field
Field
The main output field representing geologic materials.
Output
Deviations Field
Field
A field containing deviation values by which the data has been shifted.
Output
Output Object
Renderable
A renderable object displaying the variography created by the module. Output even when Allow Run is off.

Description
Allow Run
Boolean
Controls whether the module will run when applications are loaded or data changes. When on, the module runs when applications are loaded or the Execute button is pushed. When off, the module will not run unless Execute is pressed.
Execute
Button
Forces the module to run. If pressed and the application saved, it will cause the module to run when the application is loaded.
Fast Geostatistical Realization
Property
Type
Description
Randomness Generator Type
Choice: Type1, Type2, Type3, Type4
Determines the nature of the Realization deviation patterns.
Anisotropy
Anisotropy
Controls the anisotropy of the realization noise via heading and horizontal ratio.
Seed
Integer
Used in the random number generator to make realizations reproducible.
Wavelength
Double
Affects the Randomness Generator. This value is in your coordinate system units. Small values produce an output with higher frequency changes.
Min Max Confidence Equivalent
Double
Realization deviations from the nominal kriged results will be constrained to lie within the equivalent Min/Max (plume) bounds. Must lie between 51.00% and 99.995%. Theoretically 50% is the same as the nominal kriged result.
Variography Display
Property
Type
Description
Variography Z Scale
Double
Sets the vertical scaling of the variography ellipse and lines.
Display Variogram Ellipse
Boolean
Allows the user to display the variography ellipse.
Ellipse Opacity
Double
Sets the opacity of the ellipse directly.
Resolution
Integer
The resolution to use for the ellipse. Larger numbers create more detailed representations.
Ellipse Scale
Double
Scales the ellipse equally along each axis.
X Offset
Double
Translates the ellipse along the x axis.
Y Offset
Double
Translates the ellipse along the y axis.
Z Offset
Double
Translates the ellipse along the z axis.
Ellipse Color
Color
The ellipse is a solid color which can be selected using this control.
Display Variogram Lines
Boolean
Allows the user to display lines aligned with the variography ellipse.
Line Scale
Double
A scalar that sets the length of the variogram lines relative to the scale of the ellipse.
