Adds a simple test case for gas lift optimization. Currently this is
very simplistic and only covers a fraction of the gas lift optimization
code. The plan is to use this as a building block to add more tests
in the future.
Added some more debug code, and initialized some boolean variables.
The jenkins build gives a warning about that '"alq_is_limited" may be
used uninitialized', though the warning is generated in another file
(GasLiftWellState.hpp, line #44) it could be (?) caused by the fact that
"alq_is_limited" might not be initialized before calling the constructor
in GasLiftSingleWell_impl.hpp line #963..
Gives a warning if gas lift optimization is attempted for more than one
process in the MPI communicator. The plan is to implement support for
muliple processes in a later commit.
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).
This commit adds support for calculating and reporting the
dimensionless time (simulator time divided by aquifer's time
constant) and pressure (influence function evaluated at
dimensionless time) values as part of the Carter-Tracy aquifer's
'aquiferData()' reporting function.
These values are useful in their own right, e.g., for summary output
through the keywords AAQTD and AAQPD, but they are also needed for
ECLIPSE restart purposes.
