Formation damage is generally limited in the immediate near-wellbore region and needs a particular near-well flow modeling using fine gridblocks. However, near-well models are usually developed standalone and are decoupled from reservoir models. Using a standalone near-well model, which does not take into account production scenarios, cannot correctly predict well injectivity or productivity.

In this paper, we propose a new technique for the coupled modeling of the near-well flow model and the reservoir model in a simple and consistent way. In this new approach, data are exchanged and updated through boundary conditions for the near-well model and numerical productivity index (PI) (or skin factors) for the reservoir model. Examples show that this coupled modeling gives quite satisfying results.
