Case Studies

RAG Knowledge Assistant

Innovative startup in the energy sector based in Algeria.

Client

Startup innovante dans le secteur de l'énergie basée en Algérie.

Context & Challenge

In the Oil & Gas sector, it is common to accumulate hundreds of documents of different types:
Technical reports in PDF
Procedures in DOCX
Measurement tables (performance, maintenance, sensors)
Images from on-site installations
This information is essential but scattered across multiple silos. As a result:
Engineers were spending significant time trying to locate the right data.
Answers to operational questions were not always reliable.
The risk of technical and regulatory errors increased.

Objectives

Centralize and leverage multi-format data (PDFs, DOCX, images, tables).
Provide an intelligent search assistant that always cites its sources.
Reduce research time to free up capacity for analysis and innovation.
Strengthen security and traceability of the information used.

Qantra Solution — RAG Knowledge Assistant

Qantra deployed an AI assistant based on RAG technology (Retrieval-Augmented Generation), capable of understanding multiple formats and delivering contextualized answers.

The project was structured into 3 sprints of 2 weeks:

Sprint 1:
Scoping & Multi-source Integration

  • Workshops with the team to define use cases.
  • Pipeline setup to ingest PDFs, DOCX, images (via OCR), and tables.
  • First version of a simple search engine.

    • Sprint 2:
    RAG Assistant & User Interface

  • Deployment of the RAG engine with augmented generation and citations.
  • Advanced extraction for images and tables.
  • User-friendly web interface with confidence scores and links to documents.

    • Sprint 3 :
    API & Industrialization

  • Development of an API to integrate the assistant into internal tools.
  • Enhanced security: SSO, access control, audit logs.
  • Documentation and training for teams.

    • Results

    −50% search time for engineers.

    Improved reliability of answers thanks to source citation.

    Rapid adoption by technical and regulatory teams.

    Measurable gains in productivity and decision-making quality.

    Testimonial

    “We had documents everywhere: PDFs, procedures, measurement tables,
    scanned images... finding the right info was a real challenge.
    With Qantra’s RAG assistant, our teams can now get answers in just a few
    seconds, with the exact source.
    The time savings and clarity of results already make a real difference in our
    daily work.”
