Extraction built for geological documents, not just OCR

logdog.ai understands drill log structure — multi-hole files, tables that span pages, abbreviated field notes — and extracts everything into structured data.

Upload

Drop PDFs in any format, any age, even multi-hole documents. No preprocessing required.

  • Scanned legacy logs
  • Handwritten forms
  • Multiple holes per file
AI Processes

AI understands geological document structure — pages classified, tables stitched, descriptions enriched.

  • Pages automatically classified
  • Tables merged across pages
  • Lithology descriptions enriched
Download

Structured drill hole data organized by hole, ready for your software.

  • Collar, Survey, Lithology, Assays
  • Excel, CSV, or JSON format
  • Source traceability included

Automatic Page Classification

Every page is classified before extraction. The system recognizes what kind of page it's looking at and applies the right extraction strategy.

  • Cover PagesProject metadata, hole IDs
  • Collar HeadersLocation, azimuth, dip, depth
  • Log PagesLithology depth intervals
  • Assay TablesLab results, element values

Multi-Page Table Merging

Drill logs routinely span many pages. A single lithology table might run across pages 3–8, and one document may contain multiple holes. LogDog detects and stitches tables into continuous datasets per hole.

  • Automatic DetectionMatching columns and depth continuity per hole
  • Seamless StitchingMerged into one continuous dataset per hole
  • Source ProvenanceEvery row traces back to its source page

Lithology Enrichment

The AI reads the geologist's original descriptive text and extracts structured fields from it. Nothing is inferred or hallucinated — every value traces back to what the geologist wrote.

  • Rock TypeStandardized lithology classification
  • AlterationType and intensity extracted from description
  • MineralizationMineral type and percentage
Geologist's Description

Common questions

Yes — drop any PDF and the first 2 pages are processed at no cost, with no email required. You only need to provide an email address when you want to download the results, and doing so earns you a free demo code for 20 additional pages.
logdog.ai currently supports PDF files. Each page of your PDF counts as one processing credit. Scanned, photographed, and native PDFs are all supported.
Our AI extraction is highly accurate for most drill log formats. Results may occasionally need minor corrections with complex or unusual layouts. If you're not satisfied with results, contact us and we'll re-process at no additional cost.
Excel workbooks, CSV files, or JSON. We also offer a consolidated export following the industry-standard drillhole database structure used by Leapfrog, Micromine, Surpac, and Datamine.
Uploaded files are automatically deleted within 7 days (30 days for paid accounts). Your documents are never reviewed by staff and never sold or shared. Documents are transmitted to third-party AI providers (OpenAI, Anthropic, Google) solely for extraction processing. All connections use HTTPS.
