Design of a Simulation Tool for Steam Assisted Gravity Drainage： Based on the Concept of Unified Feature Modeling Scheme

Cyber-physics system (CPS) engineering brings new revolutionary opportunities for multi-disciplinary and complex processes, like oil extraction from oilsands. Based on an established unified feature modeling scheme, a software modeling framework to simulate the process of steam-assisted gravity drainage (SAGD) is proposed. The main idea was to apply CPS in the complex production engineering informatics modeling. The proposed CPS model combines effective phenomena simulation with the production tooling design for well completion and near-well bore production control. The unique representation of the planned software design is developed and expressed with graphical diagrams of the unified modelling language (UML) convention. Conservation laws were used as the governing principles, while the transport phenomena were modelled via the primary phenomenon features. The definition of this feature type represents a new expansion of the emerging unified feature scheme for engineering software modeling. The representation of typical data flows targeting to the functional simulation scenarios by applying the concept of phenomenon features was also done. Slotted liners were taken as the well-completion option and their design and specifications were included in the case study model.
