Integrated Reservoir
& Production System Modelling

CoFlow, a multi-fidelity, multi-disciplinary team environment, allows reservoir and production engineers to collaborate on the same asset, using the same software application, to make informed decisions.

CoFlow couples reservoir models and production systems to generate production forecasts for the field
Multi-Fidelity
Build fit-for-purpose models with shared proxies allowing for consistent cross-discipline results.

  • Production and reservoir models can be easily combined to create a single integrated high-fidelity model of the complete asset
  • Fit-for-purpose models for each discipline - reservoir, production and geomechanics
  • Use a different fidelity for different objectives:
    • Refined discretized reservoir model (high fidelity)
    • Upscaled discretized reservoir model (medium fidelity)
    • Decline curve model (low fidelity)

Integrated User Environment
An integrated user environment provides users with ease-of-use benefits never seen before.

Read more...

  • First application where three different disciplines truly collaborate on an asset, on the same platform
  • Guided Task Catalogue is an interactive mechanism for the entire asset team to organize and build different pieces of the reservoir model
  • Reservoir engineer looks at the simulation using a discretized model, while the production engineer may use a lower fidelity decline curve to look at the detailed description of the well and flow lines
Universal Black Oil Model
Better performance and accuracy for integrated production system models.

Read more...

  • Traditional table-based black oil models, coupled with thermally-aware correlation-based models in the wellbore and production network
  • Minimize volumetric errors across fluid model boundaries and leads to better convergence of the overall system
  • Advanced blending methodology to ensure model accuracy while maintaining the performance of a black oil system
  • Models different reservoirs producing to a single platform, while preserving the dynamic rock and fluid behaviour of each reservoir

Integrated Optimization and Design Parametrization
Seamless integration with CMOST to specify uncertainty with the base simulation model.

Read more...

  • End-to-end integrated history-matching (HM), optimization, and uncertainty analysis to enable best-in-class HM and lifecycle optimization workflows
  • Assess the sensitivity of different parameters, calibrate and history match models with field data
  • Optimize operation and completion strategies to increase production, NPV and ultimate recovery
