NEW Geophysics extension
Now with the new Import 3D SEG-Y tool you can import 3D SEG-Y data into Leapfrog to guide interpretation and help you visualise this data in the context of your geological model.
This new tool provides an intelligent parsing of SEG-Y files and auto-identifies required coordinate and data fields for most common SEG-Y formats and provides the flexibility for you to choose field locations, coordinate mapping and geo-referencing where required. Now you can:
• Control which in-lines, cross-lines and z-slices to import, in order to keep data storage and memory requirements within Leapfrog in check, with a simple reload workflow to change the choice of slices/lines.
• Digitise interpretation linework directly onto slices, then visualise modelled fault planes and reflector surfaces against other slice data.
2D / 2D CROOKED SEG-Y
Now with the new Import 2D SEG-Y tool you can import 2D planar or crooked SEG-Y data into Leapfrog to guide interpretation and help you visualise this data in the context of your geological model. Bring in historical 2D data sets as well as your newly acquired data. Using the same import interface as the 3D SEG-Y data, the tool provides an intelligent parsing of data files and auto-identifies required data fields where possible, with user over-ride where needed.
What's new in Leapfrog Geothermal 2021.1
MULTIPLE DRILLING DATASETS
The most major improvement to Leapfrog data management is here. You can now have multiple drill hole data sets in your project. You are no longer limited by needing to import all your drilling data into a single drill hole object.
So many use cases can be envisaged:
• Visualise new drilling in relation to an existing model before appending and triggering changes.
• Connect, display and model with data from different sources.
This functionality enables many new enhancements to workflows including:
• Modelling tools that allow addition of ‘contact points’ from drilling tables (deposit, erosion and intrusion surfaces) can now draw contact points from other drill hole sets.
• Vein segments need to be derived from the same drill hole set / interval table, however contact points from other drill hole sets can be added into vein surfaces using derived (linked) contact points from the points folder.
• Numeric interpolants can make use of values from a second drill hole set, by incorporating these via the points object/derived interval mid-points.
• Drillhole correlations can be made between data from different drill hole data sets.
• Add data from different drill hole sets into section layouts.
In future we plan to extend the functionality of multiple drilling sets by allowing the creation of ‘merged drill holes sets’. This creates new ways to incorporate data from multiple drillhole data sets into models.
REMAPPING DATA TABLES
It is now possible to change the data source for existing drilling data, points tables and structural data tables, and remap these to a new source. Data can be remapped from any source to:
• local CSV file,
• to CSV files located in Central Datastore, or
• to an ODBC data source.
Remapping files to Central Datastore paves the way for dynamic linking of projects to database outputs. Projects using a Central Datastore source can leverage the file versioning and ‘out-of-date’ notification functionality of Central, to ensure timely updating.
DELETING HIDDEN COLUMNS
Delivering more flexibility in the project tree with the option to delete ‘hidden’ columns such as text.
CALCULATIONS AVAILABLE ON DOWNHOLE POINTS TABLES
Work effectively with calculations now added to downhole points tables. Calculations can be performed, or categories defined on data such as LAS measurements from geophysical tools, or CPT data from ground investigations.
FILTER EXPORTED INTERVAL TABLE DATA
When exporting data from interval tables and points tables, it is now possible to filter the export using any of the filters defined for that table or for the parent collar table. Meaning only final filtered values used in model construction can be exported for archiving or further analysis, without the necessity to reproduce complex filters in Excel.
SUB-SET OF CODES RESIDUAL HANDLING
A residual length and handling method can be specified for each separate code, allowing the effective use of variable composite lengths for different code sets.
IMPROVEMENTS TO DRILLING DATA IMPORT FROM CENTRAL
Work more effectively with the new improvements made to importing and reloading drilling data from Central.
• NEW - Import new tables from the Data Room to an existing Central sourced data set.
• NEW - Append data to all tables in a Central sourced drillhole data set in a single pass. The existing behaviour of appending one table at time is still available.
• Options for importing new data columns from Central have been simplified.
• The Reload Data from Central menu options have been reorganised.
• Select multiple polyline or structural data files to import from Central data room using standard Ctrl+click and Shift+click controls.
EXPORT PLANNED DRILLHOLES TO POLYLINE
Simply right-click on your planned drillhole(s) and select Export as Polylines to simplify tasks (such as breakthrough checks) and collaborate more effectively.
• Option to select just some or all planned holes when exporting a planned drillhole group.
• Save each drillhole as a separate layer in the file and name to identify when exporting in DXF / DGN formats.
• For DXF/DGN format, import each drillhole as a separate layer or flatten to load as a single polyline.
IMPORT OF TIME DEPENDENT POINT DATA
‘Import of geophysical points’ has been relocated from the geophysics folder to the points folder and renamed ‘Import time-dependent points’.
In a major upgrade, our ‘Fence section tool’ is renamed ‘Long Sections’ and brings improved workflow for creation and editing. Now you can:
• Rapidly define a long section path based on a new or existing polyline, the start and finish points, and choose sub-sections.
• Define multiple sections with options to overlap adjacent sub-sections size (or a negative overlap for gaps).
• Define a master layout, that can be applied to all sub-sections, with options to define section layouts.
Section Layout Editor Changes
A more intuitive workflow evaluation options now selected in the layout editor, then automated onto the section. The New Section Layout window has been removed – now simply open for editing on creation.
• The New Section Layout window and Scale and Extents can now be changed in the Page Section of the layout editor.
Evaluate objects within a range onto sections
An additional benefit where sections are a required output (e.g., for reports, communications, or client deliverables). Now you can:
• Project polylines, points, and structural data onto cross-sections (if within a defined window from section plane).
• Control the projection of distance for each object, and for structural data by either closest distance or along the plane.
Continued improvement to the native support of Oasis montaj Geophysical Grids in Leapfrog, with the introduction of Crooked 2D grid and 2.5D Elevation grid imported from Geosoft .grd files.
Crooked 2D Grids
This release removes a major roadblock importing workarounds for crooked grids. Now you can:
• Import wavy/crooked 2D grids in Oasis montaj .GRD format directly into Leapfrog, from either local files, or Central data room, a connectivity providing access to a seamless transfer of crooked section data between Oasis montaj and Leapfrog.
• For Oasis montaj, write .GRD files directly into the data room. For Leapfrog you can import, reload and, be notified when files are out of date.
In future version we plan support for direct import of 3D grids (Voxels).
2.5D Elevation Grids
When 2.5D elevation grids are imported into the Geophysics folder, they come in as a planar 2D grid with elevation stored as a grid attribute. It is now possible to:
• Import 2.5D elevation grids directly from locally-stored .grd format files.
• Create topography directly from an imported elevation grid, or from one imported into the Meshes folder.
VEIN OBJECT IMPROVEMENTS
Experience fantastic NEW functionality with improvements to our vein tool.
• Where high resolution is required around dense data (such as underground development and face sampling) but low resolution is required around the periphery.
• You can now apply adaptive iso-surfacing to veins. Choose the adaptive surfacing option when creating new, or apply to existing by selecting the ‘on’ option.
• Calculate the planar reference surface default from input data (rather than horizontal by default).
Multiple Intersections per Drillhole
A new way to create complex vein models faster and to better cater for drillholes at acute angles or through a non-planar vein. Create multiple vein intersections in a drillhole with midpoint and segments generated for each, and segments classified relative to the reference plane. For new veins select this option on creation, for existing, double-click on the vein segments to switch. Combine with custom reference planes and the NEW Bulk Editing of Segments.
Bulk Editing of Vein Segments
Now you can select multiple segments using the familiar paintbrush selection tools and assign to a category (rather than a segment-by-segment basis). Segment types (hanging wall, footwall and exclude, either auto-assigned or user-assigned) are listed in the tool along with a visibility toggle so you can quickly isolate and select segments, review edits, or set different colours to segment types.
Pinch-outs and interval midpoints
It’s now possible to bulk select and edit both pinch-outs and vein mid-points in a similar way to vein segments (with points either used or excluded).
IMPORT RGB COLUMNS
Innovations in LIDAR and LASER technologies are steadily gaining traction across the geosciences. We now have:
• A more enhanced 3D visualisation with full 24-bit colour - a key attribute for subtle detection.
• Ability to import colour data (stored either as discrete R, G, and B values or as HEX RGB).
• A calculation to convert discrete R, G, B values into a HEX RGB value for display.
• Scan topography, underground or quarry walls, from fixed locations or mobile platforms (drones/vehicles).
• Core imaging companies can generate scans of surfaces, or summarise the dominant colour over intervals.
NEW SUB-BLOCKED MODEL FORMAT
Optimise efficiency with major reductions in processing times.
• A NEW sub-block model format (based on octree branching) for geometry representation.
• Up to 6 levels of sub-celling (to 1/64th of the parent cell) supported.
• Cells (and sub-cells) are only triggered if a boundary passes through them.
• Models can be rotated on 2 axes.
• Up to 75% reduction of sub-cells when compared to our existing sub-block model.
• Results in significantly smaller projects and file sizes when models are exported.
• Up to 65% reduction in processing time in sub-block count.
Optimising the size and performance of octree models is ongoing.
Sub-block model import
More eagerly-awaited developments ahead…
• Import an octree sub-block model in CSV format into Leapfrog to visualise, validate and report.
• Add new triggering and evaluations while preserving the integrity of imported categories and values.
• The minimum sub-block dimension must be a binary sub-division of the parent cell dimension (in X, Y and Z).
• Arbitrary sub-block dimensions follow this rule, with arbitrary models already defined by this geometric constraint.
• To import, select columns and define the grid: parent and sub-block sizes, to position and extent.
• If the model is rotated there is currently two pre-set options for specific file exports from Leapfrog and Surpac.
• Models with two axes of rotations are supported.
We envisage the new sub-block model to supersede the existing format (except for applications where variable height blocks are used).
You can use the NEW Grouped Mesh tool in the Combined Models folder to:
• Group mesh together for improved evaluation (outside of a geological model).
• Evaluate directly onto block models, points, and flow models.
• Allow (most) closed volume meshes in evaluations.
• Arrange in order of sequential evaluation (highest priority at the top).
• Freely edit the name, category colour legend, or set optional custom background (after default).
• Define if evaluation applies category value inside or outside mesh volume.
Previously, the only way to check if an object had downstream dependencies was to ‘fake delete’ it - then hit cancel. A risky move! Now it’s possible to safely view the inputs/outputs of any object in the project tree, with arrows and hotkeys to quickly drill down to the details.
Updates to the Confirm Delete dialogue now has links to:
• A full list of objects to be deleted and reprocessed.
• The View Relationships window.
