WellXplo™ Release Notes

⚡ Workflow Improvements

• Pro CBL/VDL cement bond module — three-track display: depth scale, CBL amplitude curve, and VDL waveform density image
• Pro Interactive depth crosshair — hover across all three tracks to read exact depth at cursor position
• Pro Click-to-draw zone boundaries — click top then bottom depth on any track to define a cement bond assessment interval
• Pro Cement Bond Index (CBI) computed per zone: Free Pipe, Microannulus, Partial Bond, and Good Bond classification with colour coding and CSV export
• Pro Geomechanics module — dynamic elastic properties (Young's modulus, Poisson's ratio, bulk and shear moduli) from DTC, DTS and RHOB
• Pro Unconfined Compressive Strength (UCS) with McNally, Militzer and Chang correlations; brittleness index (Rickman), friction angle, and mud-weight window for wellbore stability; formation presets for clastics, carbonates, shales and unconventionals

🎨 UI Improvements

• Pro VDL colormap selector: Classic Brown/Black, Grayscale, and Seismic (Blue-White-Red)

⚡ Workflow Improvements

• Pro Minvert™ Inversion — traditional-style mineral composition inversion with per-mineral endpoint matrix, per-zone parameter control, NNLS and bounded Simplex Σ=1 solvers, CPI stacked-fill track, and QC logs with actual vs predicted curves and uncertainty shading
• Pro Dual Water saturation model (Clavier-Coates-Dumanoir 1984) with iterative Newton solver — alongside Archie, Simandoux and Indonesia methods
• Pro Monte Carlo uncertainty analysis for reservoir property estimation
• Pro TIFF and raster well log image digitizer — seed-point axis detection and multi-header support
• Pro Machine learning-assisted log interpretation: regression, classification, clustering, dimensionality reduction, anomaly detection and curve-to-curve prediction
• Pro Multi-well petrophysical analysis with well-to-well correlation and QC
• Pro Subsurface temperature modelling and geothermal gradient analysis
• Pro Unconventional reservoir analysis: source rock geochemistry and TOC modelling
• Pro Preset system — save, load and share named analysis configurations across wells and sessions (Minvert™, Monte Carlo, ML Workflows)
• Pro Monte Carlo uncertainty analysis — depth-domain P10/P50/P90 profiles for any petrophysical expression; mix log curves with uncertain parameter distributions; automatic distribution fitting with goodness-of-fit ranking; envelope shading and configurable percentiles

🎨 UI Improvements

• Pro Customisable multi-track log layout — drag tracks to reorder, resize, and configure independently
• Pro Silent auto-update: session state persists across deployments; new versions load in the background with a one-click refresh toast
• Pro Depth zoom slider on log view, Minvert™ CPI track, and ML depth profile — scroll or drag to navigate any depth interval

⚡ Workflow Improvements

• Starter Interactive LAS and DLIS well log viewer with depth-synchronised multi-track display
• Starter Basic petrophysics: clay volume (Vshale), total and effective porosity, and water saturation
• Starter Resources in place estimation with customisable depth cutoffs and zone summations
• Starter Lithological curve computation and classification
• Starter Crossplot module: any two curves plotted against each other, coloured by zone or a third curve
• Starter Depth-interval zone annotation for reservoir and non-reservoir flagging
• Starter Export curve data to CSV

🎨 UI Improvements

• Starter Export log track view to PNG and PDF
