Cross Plot: Plot Definition Dialog Box
The Plot Definition dialog box is used to select the data that you want to plot and determine how it will appear. The dialog box will be empty until you select the Plot Type, and then the additional options will become available.
As you create multiple plots, a new tab is added to the bottom of the dialog box. Click on a tab to access its properties. To remove a plot, select it in the Legend dialog box and click the delete icon.
How do I cross plot well data?
-
In the Plot Definition dialog box, from the Select Type list, select the "Well versus well".
-
Select the input data for the X and Y axes.
-
Select the wells to include in the plot. Note: You can apply a polygon to limit the wells being displayed from the Polygons section of the Plot Definition dialog box.
-
Select the input data for the X and Y axes. The data points are plotted in the main plot area.
-
Optionally modify the remaining display settings. This may include changing the color of the data points, applying a color palette to the data points based on the selected data input, adding labels to the data points, and modifying the trend line.
Cross Plot Types
Well Versus Well: Cross plot the values associated with a formation top, isopach, grid or horizon at a well location. See Well versus well options...
Well Versus Well Options
X/Y/Z Axis Display Value: Select the data you want to plot. As you make your selections, additional fields will appear in the dialog box.
Well Top Value: Select the Formation to use.
Well Isopach Value: Select the Top Formation and Bottom Formation. This difference between these two values is used.
Grid Value: Select a Grid, and then specify addition parameters to determine which grid value to use.
Intersection Location: Select
the location where you would like to
take the grid value from.
Well top location:
The
value of the grid at the location along the well bore that the
formation top is placed.
Top hole location:
The
value of the grid at the top hole location. You will also be required to specify the location.
Bottom hole location:
The
value of the grid at the bottom hole location
Grid Values: Specify how to determine the grid value.
Interpolated:When intersecting wells against
a grid, use
the interpolated value at the exact well location. Users should be
cautious using this option when working with grids that have faults.
Raw:Use the value stored in the grid
cell nearest
the well location as is.
Horizon Value: Select a Horizon, and then specify additional parameters to determine which horizon value to use.
Intersection Location: Select
the location where you would like to
take the grid value from.
Well top location:
The
value of the grid at the location along the well bore that the
formation top is placed.
Top hole location:
The
value of the grid at the top hole location. You will also be required to specify the location.
Bottom hole location:
The
value of the grid at the bottom hole location
Horizon Search
Radius:
Only retrieve data from the horizon if it is within this distance from
the well.
Select Wells: Select the wells you want to use from the selection list, from the Basemap, or using a filter.
Specify Sources: Specify a source. If no source is selected then the first top from the database is used.
Horizon Versus Horizon:Cross plot the values of two horizons on specific seismic lines. See Horizon versus horizon options...
Horizon Versus Horizon Options

Grid Versus Grid: Cross plot the values of two grids. See Grid versus grid options...
Grid Versus Grid Options
Select X Axis: Select a grid from the list to be plotted on the X axis.
Select Y Axis: Select a grid from the list to be plotted on the Y axis.
Seismic Line Versus Seismic Line: Cross plot seismic data values within in a specific data window. See Seismic versus Seismic options...
Seismic Versus Seismic Options
Select Seismic: Select the seismic files you want to use from the selection list, from the Basemap, or using a filter.
Windowing Methods: Select
a windowing method.
Select X Axis: Use the working set version of the line, or select another version from the list o be plotted on the X axis.
Select Y Axis: Use the working set version of the line, or select another version from the list o be plotted on the Y axis.
Well Log Curve Versus Well Log Curve: Cross Plot log curve data within in a specific data window. See Curve versus curve options...
Curve Versus Curve Options
Select Wells: Select the well(s) you want to use from the selection list, from the Basemap, or using a filter.
Specify Log Curve Sources: Specify a source. If no source is selected then the first curve from the database is used.
Windowing Methods: Select
a windowing method.
Define Between Depth Range: Enter a Start Depth and End Depth to limit the data being plotted.
Define Between Tops: Select an Upper Formation and Lower Formation with optional offsets to limit the data being plotted.
Use Entire Curve: Cross plot the entire curve.
Select X Axis: Select a curve from the list to be plotted on the X axis.
Select Y Axis: Select a curve from the list to be plotted on the Y axis.
Column Versus Column from Columnar ASCII File: Cross plot data from one column in a columnar ASCII file against data in another column. See Column versus column options...
Column Versus Column Options
Columnar ASCII File: Select a file and define the columns you want to plot.
Select X Axis: Select a column from the list to be plotted on the X axis.
Select Y Axis: Select a column from the list to be plotted on the Y axis.
Additional Options
Display Settings: The display settings will change depending on the plot type. See Display Settings...
Display Settings
Units: Select the units to display. Choose between Meters and Feet.
Measurement: Select the depth reference. Choose between TVD and Sub Sea.
Marker Color: Set
