Knowledge Graphs for Oil & Gas
Short answer. A knowledge graph for oil & gas connects country, basin, formation, well, event, sensor, feature, model, risk, advisory, procedure, action and outcome as explicit relationships. It gives drilling AI the geological and operational context it lacks, and makes every recommendation traceable to its evidence.
Knowledge Graphs
What problem does this solve?
Lessons from past wells are spread across daily and end-of-well reports, spreadsheets and people, and are not available to engineers or models at the moment they are needed.
What does the architecture look like?
How does it work?
The ontology
The graph models the chain from country and basin to formation and well, then from events and sensors to features, models, risks and advisories, and finally to procedures, actions and outcomes.
Neo4j or GraphDB
Neo4j suits operational queries such as offset-well lookup; RDF stores such as GraphDB suit standards-based ontologies and inference.
Feeding AI
Graph context is used for model features, cluster assignment in federated learning and GraphRAG retrieval for engineering Q&A.
Closing the loop
Recording which advisory led to which action and outcome turns the graph into an evidence base for improving models and procedures.
Implementation considerations
- Start with a narrow ontology and grow it from real queries.
- Entity resolution for well and formation names is essential.
- Assign data owners for each part of the graph.
Frequently asked questions
What is the first use case for a drilling knowledge graph?
Offset-well lookup: finding similar wells and their events during planning and real-time operations.
