Implements gas lift optimization for groups.
Extends PR #2824 to include support for GLIFTOPT (item 2, maximum lift gas supply for a group) and group production constraints. The optimization is split into two phases. First the wells are optimized separately (as in PR #2824). In this phase LIFTOPT and WLIFTOPT constraints (e.g. maxmimum lift gas injection for a well, minimum economic gradient) are considered together with well production constraints. Then, in the next phase the wells are optimized in groups. Here, the ALQ distribution from the first phase is used as a starting point. If a group has any production rate constraints, and/or a limit on its total rate of lift gas supply, lift gas is redistributed to the wells that gain the most benefit from it by considering which wells that currently has the largest weighted incremental gradient (i.e. increase in oil rate compared to increase in ALQ).

* well, or if that is not possible, if we 2) should reduce the amount
|
|

* of lift gas injected due to a too small gain in oil production
|
|
||||||
* (with the current lift gas injection rate)
|
|
||||||
* - For 1) above, we should not add lift gas if it would cause an oil
|
|
||||||
* rate target to be exceeded, and for 2) we should not reduce the
|
|
||||||
* amount of liftgas injected below the minimum lift gas injection
|
|
||||||
* rate.
|
|
||||||
*
|
|
||||||
* NOTE: If reducing or adding lift-gas further would cause
|
|
||||||
* one of the well targets like ORAT, WRAT, GRAT, LRAT, CRAT, RESV, BHP,
|
|
||||||
* to become violated we should stop the lift gas optimization
|
|
||||||
* loop.. and then updateWellControls() will later (hopefully) switch the well's
|
|
||||||
* control mode from THP to the mode of the violated target.
|
|
||||||
*
|
|
||||||
* - Lift gas is added if it is economical viable depending on
|
|
||||||
* the ratio of oil gained compared to the amount of liftgas added.
|
|
||||||
*
|
|
||||||
* - Lift gas supply may be limited.
|
|
||||||
*
|
|
||||||
* - The current value of liftgas for the well is stored in the WellState object.
|
|
||||||
*
|
|
||||||
* - It is assumed that the oil production rate is concave function F
|
|
||||||
* of the amount of lift gas, such that it increases initially due to the
|
|
||||||
* reduced density of the mixture in the tubing. However, as the
|
|
||||||
* lift gas supply is increased further, friction pressure losses in the
|
|
||||||
* tubing become more important, and the production rate peaks and
|
|
||||||
* then starts to decrease.
|
|
||||||
* Since lift gas injection has a price, e.g. compression costs can
|
|
||||||
* be expressed as a cost per unit rate of lift gas injection,
|
|
||||||
* it must be balanced against the value of the extra amount of
|
|
||||||
* oil produced. Thus there is a "minimum economic gradient" of oil
|
|
||||||
* production rate versus lift gas injection rate, at which the
|
|
||||||
* value of the extra amount of oil produced by a small increase in
|
|
||||||
* the lift gas injection rate is equal to the cost of supplying the
|
|
||||||
* extra amount of lift gas. The optimum lift gas injection rate is then somewhat
|
|
||||||
* lower than the peak value.
|
|
||||||
*
|
|
||||||
* Based on this assumption, we know that if the gradient (derivative) of F is
|
|
||||||
* positive, but greater than the economic gradient (assuming the
|
|
||||||
* economic gradient is positive), we should add
|
|
||||||
* lift gas. On the other hand, if the gradient of F is negative or
|
|
||||||
* if it is positive but smaller than the economic gradient, the amount
|
|
||||||
* of lift gas injected should be decreased.
