WellCAD 5.8
Updates and Build Notes
Build 315
August 30th, 2024
Basic Module
Header Editor
- HeadCAD integration within the WellCAD Header Editor: The functionality of HeadCAD has been fully integrated into the WellCAD Header Editor, leading to the discontinuation of the standalone HeadCAD application.
- New Header forms workflow: New header forms can now be created in WellCAD (File > New). Headers already attached to a borehole document can be edited in-place using the header editor (Tools > Header Editor).
- Diagrams and chart Display: Polar & Rose diagrams, cross-plots, pie charts, histograms, Schmit plots, deviation diagrams, ternary plots, spinner flowmeter calibration charts, CBL charts, and CBL calibration parameters can now be displayed in dedicated header objects, which are dynamically linked to logs in the borehole document.
- New Hyperlink Object: A new hyperlink object (e.g., URLs or links to media stored in the cloud) can be added to header forms.
- Dynamic Table: A dynamic table object has been introduced to present the data from linked logs in a spreadsheet format.
- Stacking Pattern Log: Legend objects have been updated to accommodate the Stacking Pattern log.
Groundwater
- Transmissivity Calculations: A process to compute the transmissivity of a formation has been added to the collection of groundwater processes.
- New Units: New units are available for the Hydraulic Conductivity process.
Installer
- Automatic Updates: WellCAD will automatically detect available updates and prompt the user before installation.
Other Features
- New Colour Display for Picker Dialog Boxes: New colour picker dialog boxes will offer an extended range of default colours.
- New Colour Gradient Palettes: New default colour gradient palettes will be installed with the new version.
- UI Changes: The document protection icon has been moved to the bottom of the WellCAD workspace, next to the time display.
- Pie Charts: The functionality of the Chart log has been extended and pie charts can now be displayed for Litho, Strata, Core Desc, Structure and other log types.
- Updated Histogram View: A new type of histogram view for dip counts has been developed.
- Polar Projection Enhancement: The Polar plots have been enhanced to allocate more visual and display objects.
- Log Slicing: The options for the log slicing process have been combined into a single dialog box improving usability.
- Depth Matcher: Three options have been added to aid depth match operations: “Undo”, “Redo” and “Reset Matching”.
- Geological Data Export to .LAS Files: Codes and descriptions for geological symbols will be exported into the optional header section of LAS version 3.0 files.
- Duplicate logs of the Same Dataset: The display of two sets of the same dataset/logs is now allowed.
Image and Structure Interpretation (ISI) Module
Fracture Topology
- Structure Interval Statistics: The Structure Interval Statistics process has been expanded to include Pxy statistics, enabling the determination of fracture frequencies and intensities in one, two, and three dimensions.
- Calculation of fracture topology descriptors: Includes the distribution of node and branch proportions, line and branch connectivity, and the number of branches to the number of lines ratio.
- Pxy statistics to determine fracture frequency and intensity (density) in one, two and three dimensions.
- Structure Log Display: The display of X-, Y- and I-nodes can be enabled in the properties of a structure log when displayed in projection mode.
- Node and Branch Distribution: Node and branch distribution diagrams have been added to the Polar & Rose log, Chart objects, and Dips charts.
Other Features
- Interval Statistics for Fracture Spacing: The ability to determine the fracture spacing has been added to the structure interval statistics process.
- New Display for Rose Diagram: Rose diagram wedges are displayed using the colours of the classification attributes.
- Updated Diagrams: The display for the Woodcock diagram has been updated.
- Shortcut Key for Partial Picks: The shortcut key for partial picks can now be defined by the user.
- Partial Picks Setup: The start and end points of a partial pick can be fine-tuned by holding down the shortcut key (“P”) and dragging them.
- Aperture Display: The aperture of structural features can now be displayed in 3D logs.
- Caliper Resolution: The 3D log in the ISI workspace now automatically adjusts the resolution of the caliper component.
- Pipe Deformation Detection: A new ellipse fitting process has been added to enable detection and quantification of borehole or pipe deformations.
- Breakout Detection: A process to automatically detect breakouts from image logs is now available.
- Core Cropper Templates: Layout templates for the Core Cropper workspace can now be saved and applied.
- Core Cropper “rotate left”: A button “rotate left” has been added to improve usability.
- Radius to/from Diameter Process: The Radius to / from Diameter process is now available in the ISI Module > Image Log menu.
- Metadata Bar Icons: Header icons are added to substitute lightbulb icons when dealing with metadata display types.
- View Angle Value Updates: The view angle value is updated on the title while rotating the log.
Full Waveform Sonic (FWS) Module
Picking
- New Picking System: A new first arrival picking algorithm based on kurtosis changes of the FWS signal has been added.
Methods
- New Empirical Shear Wave Velocity Methods: Shear wave velocities can now be estimated using popular empirical compressional waves relationships.
Automation Module
Functions
- New and Updated Automation Functions: New and updated automation functions are available supporting various processes in WellCAD:
- Creation of linked logs (log cloning).
- Structure interval statistics updated to support fracture topology.
- Shear wave velocity estimation.
- Transmissivity determination.
- Automatic breakout picking.
Bug Fixes
v5.7 fixes
- Fracture Height Calculation Process: The fracture height calculation process now takes partial picks correctly into account.
- Partial Picks: Partial picks keep their feature depth after the apparent to true correction.
- Snap Grid Sensitivity: Switching the units of the ruler bar is now handled correctly.
- WellCAD Links: Some links included in the Help Files are now fixed and content can be accessed.
- Depth Shift Functions: Depth shifting operations are allowed for all types of integers.
- TFD Imports in Automation: The automation function now correctly imports all channels based on the specified configuration file.
