Maintain Flow Control and Efficiency
By modeling laminar, transitional, and turbulent flow regimes, teams can optimize annular transport efficiency under dynamic drilling conditions. The simulation enables real-time visualization of particle concentration and flow transitions to anticipate challenges before they occur. This improves hydraulic energy management, reduces NPT and delivers measurable ROI through reduced pump wear and improved overall circulation stability.

LIVE STATE EVOLUTION
Deploy on-prem, private cloud, or isolated networks. Supported hardware tiers: X1/X3 simulators, Laptop, and Online. Teams can also rent the Endeavor Experience Center for executive demos, assessments, or multi-crew exercises. Typical session: configure scenario parameters, run the study and/or simulation session, review KPIs, and export results.
Yes. Import well data via WITSML 1.4/2.0 or CSV/JSON, or ingest parameters directly through RADAR7. Field inputs—well schematics, logs, tool states, rates, and pressures—initialize a runtime digital twin model of the well for physics-based training and operational planning (Drilling Well on Simulator). APIs and versioned adapters are customized upon request.
The model predicts annular flow pattern transitions based on real-time hydraulics, fluid properties, geometry, and rate changes, validated against established flow-regime behavior and field signatures. Accuracy is highest within operating envelopes where inputs are known and flow is hydraulically governed, such as during rate ramps, displacement changes, or fluid swaps. Where cuttings behavior or transient instability dominates, the simulator exposes transition thresholds and sensitivity ranges rather than a single fixed regime.
Inputs typically include the operation configuration—well profile or trajectory, fluid properties, equipment and tool states, boundary conditions, and rate or pressure schedules. Outputs and KPIs capture the scenario’s hydraulic, mechanical, and fluid responses, including pressure and flow behavior across the system, evolving fluid properties, and equipment performance. Results also capture event detection and time-based cause-and-effect responses to operator actions. Detailed datasets, replays, and assessment metrics can be exported for engineering review, training records, or planning documentation.
Enterprise deployments support role-based access control, secure authentication, and encryption of data in transit and at rest. The platform can be deployed on-premises, in a private cloud, or in an isolated environment to meet operational and regulatory requirements. Support is provided under defined SLA tiers, with controlled release management and long-term support options available for production environments.
Run this simulation anywhere.
Every scenario in Endeavor’s simulation library can run individually or as part of the complete suite on any simulation deployment. Move between X-Series hardware, workstation, laptop, and streamed access without rebuilding the scenario or changing its RuntimePhysics™ behavior.
