From Scanned PDFs to Structured Data.

NDepthextracts structured tabular data from scanned core analysis reports, mud logs, and subsurface PDFs. AI reads handwritten notes, faded tables, and complex multi-column layouts with high accuracy.

What It Processes

Specialized AI for Every Document

Specialized AI models trained on thousands of geological documents for maximum accuracy.

  • Core Analysis
    Extract Porosity, Permeability & More
    Digitize decades of core analysis reports. Our AI reads handwritten notes, faded tables, and complex multi-column layouts with high accuracy.

    • Depth intervals automatically extracted and validated
    • Porosity, permeability, saturation values captured
    • Lithology descriptions parsed and structured
    • Multi-page tables merged automatically

  • Mud Log Shows
    Hydrocarbon Show Extraction
    Pull gas readings, show descriptions, and formation tops from mud logs - even from the messiest handwritten field reports.

    • Gas readings and show types extracted
    • Formation tops and depth intervals
    • Fluorescence and cut descriptions
    • Standardized show classification

How NDepth Works

Every document goes through a six-stage pipeline. AI handles the heavy lifting - you handle the final QC.

  1. OCR & Enhancement
    Advanced OCR with auto-rotation, deskew, contrast enhancement, and column detection. Low-confidence pages are automatically re-processed with enhanced imaging.

  2. Structure Classification
    Every page is classified by visual structure: tabular data, graphical logs, maps, photographs, or forms. Tables always take priority over other content types.

  3. Table Type Classification
    Tabular pages are classified into dozens of specific types using column fingerprinting, keyword matching, and header analysis. Each type gets a specialized extraction model.

  4. Intelligent Extraction
    Data is extracted with column alignment validation, depth continuity logic, ditto mark resolution, and precise handling of multi-page tables that span across pages.

  5. Duplicate Detection
    Multi-signal dedup using Jaccard similarity on headers, sample number overlap analysis, depth range intersection, and continuation detection to prevent data duplication.

  6. Data Validation & QC
    Values are validated against geological ranges (porosity 0-40%, grain density 2.0-3.5 g/cc). OCR errors are auto-corrected and out-of-range values are flagged for review.

Metadata

Every Field, Automatically

NDepth identifies and standardizes well metadata from headers, cover pages, and document body text.

  • API Number
    Standardized to 14 digits with state code validation
  • Well Name
    Parsed from headers, cover pages, and body text
  • Operator
    Matched to known operator names
  • Laboratory
    Normalized lab names (Core Labs, Weatherford, etc.)
  • Formation
    Geological formation and member identification
  • County & State
    Full county name, 2-letter state abbreviation
  • Field Name
    Oil/gas field identification from document context
  • Date
    Normalized to YYYY-MM-DD from any format

Capabilities

Built for the Worst Documents

Faded 1960s photocopies. Handwritten notes. Rotated pages. Multi-column layouts. If it was important enough to scan, it's important enough for us to read.

  • Drag & Drop Upload
    Upload single files or batch hundreds at once. PDFs, TIFFs, JPEGs, PNGs - even rotated and degraded scans. Processing starts automatically.
  • Metadata Extraction
    API numbers, well names, operators, labs, formations, counties - all parsed from headers, cover pages, and body text. Standardized to PPDM format.
  • Page Classification
    Every page is classified by structure and content type. Core analysis, mud log shows, completion data, DSTs - each gets a specialized extraction pipeline.
  • Multi-Table Merging
    Tables that span multiple pages are automatically detected and merged. Continuation markers, depth range analysis, and header matching ensure nothing is missed.
  • Excel & CSV Export
    Download structured data as Excel spreadsheets or CSV files, ready for import into Petrel, Kingdom, or any analysis tool. One file or batch export entire orders.
  • QC Portal & Review
    Side-by-side comparison of extracted data against the original document. Flag issues, approve extractions, and track quality across your entire dataset.
