Stratigraphic Modeling | Show Trend

Trend display is made according to the selected polynomial degree. By using the parameters in the window that opens when the show trend process is entered, the trend surface is produced by taking into account sample distributions of different polynomial degrees of lithology or interval data.

When a 1st-degree polynomial is used, a global trend surface with a single slope is produced, while when a 2nd-degree polynomial is selected, a more local parabolic trend surface is produced. This feature is used to see the statistical distribution of the data to be modeled.

OptionDescription
X RangeIt is the distance value between the grid points to be produced in the X direction.
Y RangeIt is the distance value between the grid points to be produced in the Y direction.
IntervalThis is the area where the intervals defined in the project are selected.
LithologyThis is the area where the lithology list used in the project is displayed.
Show TrendWhen this option is activated, a trend surface is produced. If it is made passive, the surface belonging to the selected lithology or interval is produced.
Trend Polinom Degree

This is the area where 1st-degree and 2nd-degree polynomial selection is made. The 1st order polynomial produces a linear trend surface, while the 2nd order polynomial produces a parabolic trend surface.

Coordinate FilterThe trend surface is the area where we can select the coordinates (Top, Bottom, Lower, etc.)  of the lithology or interval to be produced.









1. Trend surface produced using 1st Degree Polynomial

2. Trend surface produced using 2nd Degree Polynomial


When a 1st-degree polynomial is used, a global trend surface with a single slope is produced, while when a 2nd-degree polynomial is selected, a more local parabolic trend surface is produced. This feature is used to see the statistical distribution of the data to be modeled.
