Horizontal Multifrac Enhanced Frac Region Model

With this model, you can specify an improved effective permeability (k₁) in a region around the fractures.

It is a rectangular model that contains an inactive horizontal well fed by multiple identical and equally-spaced transverse fractures. X₁ describes the extent of the improved permeability region. The width of the reservoir is defined by the distance between the tips of the fractures, and the length of the reservoir is defined by the horizontal well length.

The model simulates three linear flow regimes:

1. Flow within the fracture.

2. Flow within the enhanced permeability region toward the fractures.

3. Flow within the non-enhanced permeability region toward the fractures.

Note:

A detailed description of the model is given by Stalgorova and Mattar (2012).
