Abstract

This presentation introduces our  wellbore simulator which currently can perform single-phase injection & production, two-phase steam injection in different wellbores, SAGD circulation & injection, and multi-phase and compositional simulations. The simulator is also  embedded with an annulus heat transfer simulator and semi-numerical method is developed from series of FLUENT simulations for improving heat loss calculation accuracy. A Windows-based interface is developed for preparing data and results visualization. Our future work includes improving existing functions to handle more complex wellbore configurations and field-scale applications and developing parallelization and more efficient differentiation method to speed the wellbore simulation.
