Import & harmonisation

All corporate well data is ingested into a single project database and harmonised into one consistent measurement system — curve families, units and sampling — before any calculation runs.

Data ingestion

• Logs — LAS and DLIS import, including multi-run suites.
• Tabular data — XLS/CSV tables, object properties and blocked (flag) curves.
• Core — all core study types, classified by study, with core photographs.
• Inclinometry and stratigraphy — survey data and stratigraphic markers.
• Log-view headers, custom Python scripts and images.

Curve family and unit assignment

• Family assigner — automatic recognition of curve type (GR, RHOB, NPHI, RT, DT …) with manual override.
• Unit assigner — automatic unit-of-measure assignment per curve.
• Per-curve normalisation of working units — RHOB → g/cm³, NPHI → v/v, DT → µs/m, RT → Ohm·m, GR → gAPI — so thresholds and coefficients remain valid regardless of the stored units.

Harmonisation and run handling

• Run detection — automatic identification of logging runs and intervals.
• Best-log selection — pick the representative curve when several runs overlap.
• Log resolution — estimate and normalise sampling.
• Automatic splicing — merge runs into a single continuous curve.
• Outlier and null handling — remove outliers, cut or replace null values, drop thin interbeds.
• SP normalisation — align spontaneous-potential baselines across wells.

Project statistics

Project statistics and extended well statistics build a reference picture of the whole well stock — the basis for QC and for consistent rules across the field.
