Using Litho-Fluid Models

Litho-fluid models from DUG Distill can be incorporated into crossplots. This can be a valuable tool when differentiating stratigraphy and identifying lithologies in the crossplot.

Selecting the model

  1. Open an existing crossplot or create a new crossplot.    
  2. Open the LithoFluid Model tab.
  3. Select a single litho-fluid model (.dustat) or an interface model (.dupdf).
  4. PDF attributes: Select the distribution from the model to plot. These should  correspond to the selected horizontal and vertical crossplot volumes.
  5. Attribute Scale: Apply a multiplier to the horizontal and vertical model values to correct for different model units or reflectivity adjustments
  6. Model Depths: Select the model depths to view
    • Tip: Multiple ellipses can be displayed. To deselect all, right-click a selected depth and choose Deselect All.
  1. Litho-Fluids:
    • Colour: Set the PDF ellipse colour
    • Ellipses: Enable to show the PDF ellipse in the crossplot
    • Hilite: Enable to highlight corresponding points from the volumes in section views (as geobodies)
    • Volume: The gross rock volume of the highlighted areas (with highlight enabled)
    • Export volume: Export the geobodies as volumes (see Exporting volumes).
    • Export crossplot data: Export crossplot ellipse points as a .tsv text file (with or without source coordinates).
    • Tip: Click the circle at the bottom of the Litho-Fluids model to show/hide all the ellipses.
  2. Display style of the ellipses is controlled from the View tab (see Configuring Crossplots).

Note: When highlighting geobodies and ellipses overlap, entries at the top of the list take precedence over lower ones.

Here is an example of geobodies highlighted in the IL/CL View:

Using intercept and gradient PDFs

Litho-fluid interface models (intercept and gradient) from DUG Distill can be displayed in crossplots.

Display intercept and gradient PDF attributes in crossplot
  1. Open an existing crossplot or create a new crossplot
  2. To generate the intercept and gradient volumes in Insight, see Intercept/Gradient.
    • Intercept volume: horizontal data set
    • Gradient volume: vertical data set.
  3. Open the LithoFluid Model tab.
  4. PDF Model: Select the litho-fluid interface model (.dupdf format)
  5. PDF Attributes: Select the distribution from the model to plot (“intercept_vs_gradient”)
  6. Model Depth: Select the model depths to view
    • Note: Right click and select Zoom to fit to ensure active ellipses are visible in the window.
  7. Scale: Apply a multiplier to the horizontal and vertical model values to correct for different model units and/or reflectivity adjustments
