TECHNOLOGY
AI reservoir simulation technology.
The agent, the model-authoring layer, the benchmark and the simulator work together as one engineering system.
CLARISSA: the reservoir engineering AI agent
CLARISSA is the AI reservoir simulation agent and user-facing system. It translates engineering requests into model-building actions, uses tools, runs simulations and returns results for review.
PetroScript: structured model authoring
PetroScript is the structured authoring layer used to convert engineering intent into simulator-ready inputs while keeping model construction explicit and verifiable.
RIGOR: evaluating reservoir engineering agents
RIGOR is Blauweiss's reservoir-engineering benchmark. It evaluates authoring, editing, repair, successful simulation execution, output agreement and engineering-analysis correctness.
OPM Flow: simulator execution and feedback
OPM Flow provides a transparent simulator execution target for testing, validation and reproducible reservoir-model workflows. CLARISSA also works with ECLIPSE-compatible deck conventions.
How agentic reservoir simulation works
The workflow connects a language-based engineering request to an executable reservoir model. CLARISSA coordinates the work; PetroScript makes model construction explicit; OPM Flow executes the case; and RIGOR provides tasks and criteria for evaluating agent performance.
- Describe the case. Start with the reservoir task, available inputs, constraints and engineering objective.
- Build and check inputs. Translate the request into structured model-building actions and simulator-ready inputs. Validation checks whether those inputs satisfy the task requirements.
- Run and inspect. Execute the simulation, examine the simulator feedback and review the resulting engineering interpretation.
Simulator execution is evidence that a case runs. Engineering review still needs to consider the supplied data, assumptions and whether the model answers the intended question. Benchmark results measure performance on defined tasks; they do not establish accuracy for every field case.
