Modelling & Optimization of Advanced
SAGD Wellbore Completions


Due to the unique challenges of thermal SAGD operations, advanced well completions and configurations are becoming the industry standard. Determining an appropriate well design is a complex process that involves optimizing costs and productivity. Simulating advanced wellbore completions and managing their impact on reservoir performance is challenging. Using STARS' FlexWell, engineers are able to model complex wellbore design and fluid flow behaviour while being coupled to the reservoir simulator. This helps engineers to better capture the wellbore-reservoir interaction, and effectively manage production profiles and recovery in order to maximize the net present value (NPV).

The following main points are covered:
  • Modelling the wellbore-reservoir interaction using STARS' FlexWell
  • Optimizing the capital-intensive circulation stage using STARS' FlexWell and CMOST
  • Evaluating the impact of various completions and flow-control devices on steam chamber conformance and reservoir performance
