Coupled Well Card (e-W)

The coupled well card allows the user to specify injection and production (withdrawal) wells, whose conservation equations are fully integrated into the conservation equations for the reservoir. Solutes can be injected through coupled injection wells and extracted by production wells. Wells are specified by defining a well trajectory and an injection/production schedule. Both types of wells can be either rate or pressure controlled. For injection wells, the coupled-well model injects water at the specified rate, unless the maximum pressure limit is exceeded, in which case the injection rate is controlled by this pressure limit. For production wells, the model functions in a similar way except that it will become pressure controlled if the well pressure is below the minimum pressure limit.
