Near Wellbore Modeling

The Near Wellbore Modeling (NWM) module allows you to generate a detailed local model around one or more wells in an existing full-field ECLIPSE model. The aim is to improve both the modeling of wellbore flow and its interaction with the near wellbore reservoir region.

By default, the near wellbore model inherits data from the full field model. This coarse model can be improved in a number of ways:

• You can improve well definitions by using an advanced Well Editor to edit wellbore hierarchy, path, completion strategies and to set up a multi-segmented wellbore flow models.
• You can model advanced well bore completions strategies using casing, production tubing in line and flow control valves.
• You can import geological scale rock properties, which take precedence over properties taken from the full field model.
• You can specify near wellbore reservoir fluid and rock property modifications.
• You can generate local grid refinements (LGRs) automatically around wells and inserted into the full field model grid. These include both structured (Cartesian) LGRs, as traditionally used in ECLIPSE, and unstructured LGRs, which allow variable density refinements and radially symmetric grid refinements along vertical, horizontal and deviated wellbores.

  Once generated, you can insert the near wellbore model back into the full field model simulation or simulate it independently. In this latter case, flux or pressure at the boundary between the near wellbore model is extracted from a full field model simulation, and used to make the full field model cells inactive when simulating the near wellbore model.

  The NWM module has a dedicated graphical user interface and is highly automated. This interface includes specialized 2D and 3D along-wellbore visualization tools.
