Importing GEOH5 Volumes

Insight can import volume data from a GEOH5 file. Two GEOH5 object types are supported:

  • Block model — imported as 3D stack depth volumes. Each block model property is imported as a separate volume, and a 3D survey is automatically created for each block model.
  • Vertical 2D grid — imported as 2D stack volumes. Each grid property is imported as a separate volume, and all grids from the file share a single 2D survey.

Launching the importer

  1. In the Control Panel, select the Import menu.
  2. Click Volumes > GEOH5 Volumes.

Basic settings

  1. At the GEOH5 object type field, select the type of object to import: Block model or Vertical 2D grid.
  2. Click Select file and browse to the GEOH5 file you want to import from.
  3. Review the list of objects available in the file. The columns shown depend on the selected object type.
  4. Click Next to continue.

Importing GEOH5 block models

When Block model is selected in the GEOH5 object type field, the following information is shown for each block model in the file:

  • Name: the name of the block model.
  • # Properties: the number of supported properties (float and referenced types).
  • # U / V / Z Cells: number of cells along each axis.
  • Azimuth: counter-clockwise rotation of the block model around the vertical axis.
  • |x| / |y| / |z|: total cell length along each axis.

Note: Block models with no supported properties will not be imported.

Importing Vertical 2D grids

When Vertical 2D grid is selected  in the GEOH5 object type field, the following information is shown for each grid in the file:

  • Name: the name of the 2D grid.
  • # Properties: the number of supported properties (float, referenced, integer, and boolean types).
  • # U: number of cells along the U axis (horizontal, along the line direction).
  • # V: number of cells along the V axis (vertical).
  • U Size: size of each cell along the U axis.
  • V Size: size of each cell along the V axis.
  • Azimuth: rotation of the 2D grid around the vertical axis.

Note: Grids with no supported properties will not be imported.

Block model sequences

Configure the output extents for each block model. Use Previous block model and Next block model to navigate between block models.

The Block model name of the current block model is shown at the top of the page. The following information is also shown:

  • # U Cells: number of cells along the U axis, followed by the x-axis extent in the format x: (origin, end).
  • # V Cells: number of cells along the V axis, followed by the y-axis extent in the format y: (origin, end).
  • # Z Cells: number of cells along the Z axis, followed by the z-axis extent in the format z: (origin, end).

Set the spacing (in project units) for each volume sequence to map the block model's irregular grid (U, V, Z) to Insight's regular sequences (IL, CL, Vertical):

  • Inline spacing: spacing between each inline section.
  • Crossline spacing: spacing between each crossline section.
  • Vertical spacing: spacing between each depth slice.

The Output extents section updates automatically as you adjust the spacing values.

Note: Warnings are shown if the output sequence is too large. The Next button is disabled until any invalid sequences are resolved.

Vertical 2D grid sequences

Configure the output extents for each vertical 2D grid. Use Previous grid and Next grid to navigate between grids.

For each grid, the following information is shown:

  • Vertical 2D grid name: the name of the 2D grid.
  • # U: the number of cells in the U axis (horizontal, along the line direction), followed by the x-axis extent in the format x: (origin, end) and the y-axis extent in the format y: (origin, end).
  • # V: the number of cells in the V axis (vertical), followed by the z-axis extent in the format z: (origin, end).

Set the spacing (in project units) for each volume sequence to map the grid's regular grid (U, V) to Insight's regular sequences (CMP, Vertical):

  • CMP spacing (m): the spacing between each CMP position along the line.
  • Vertical spacing (m): the vertical sample spacing.

The Output extents section updates automatically as you adjust the spacing values.

Note: Warnings are shown if the output sequence is too large. The Next button is disabled until any invalid sequences are resolved.

Output settings

  1. Click the folder icon at Output directory name to select where the imported volumes will be saved. Alternatively, select a recently used directory from the dropdown list.
  2. At Class (data type), choose a data class to apply to all output volumes. This can be changed per volume after import.
  3. Optionally, add any relevant information in the Notes field.
  4. Click Next to begin the import. A confirmation message is displayed on success. Alternatively, click Quit to stop importing the GEOH5 volume.

Block model: Volumes are named using the convention BlockModelName_PropertyName. If volumes with the same name already exist in the output directory, you will be prompted to overwrite them.

Vertical 2D grid: One 2D stack volume is written per property, named after the property. All grids from the file are imported as lines into a shared 2D survey, named after the first grid in the file.
