Implements gas lift optimization for a single StandardWell. Support for
gas lift optimization for multi-segment wells, groups of wells and
networks is not implemented yet.
The keywords LIFTOPT, WLIFTOPT, and VFPPROD are used to supply parameters for
the optimization. Also adds support for summary output of liftgas
injection rate via keyword WGLIR.
Previously, we exported an unordered map containing all names of
wells that are not present in the local part of the grid.
As we envision to have wells that are distributed across multiple
processors, this information does not seem to be enough. We need
to be able to set up communication for each well. To do this we need
to find out who handles perforations of each well.
We now export a full list of well name together with a boolean
indicating whether it perforates local cells (vector of pair of string
and bool).
This is in preparation of adding support for outputting the network
node pressure quantity, GPR, to the summary file. In particular,
'GroupValues' is renamed to 'GroupAndNetworkValues' and has new
individual datamembers for the former group-level data and the new
node-level data.
Update BlackoilWellModel::groupData() and CollectToIORank
accordingly and bring the parallel restart facility in line with the
new layout.
This commit adds support for reporting the simulator's guiderate
values at the well and group levels to the output layer through the
wellData() and groupData() member functions. We add several new
member functions that collectively assemble the values and assign
them to objects of type Opm::data::GuideRateValue for subsequent
output to the summary and restart files.
In particular
getGuideRateValues(const Well&) const
getGuideRateValues(const Group&) const
retrieve the guiderate values for all phases for those individual
wells and groups for which the guideRate_ data member defines a
value. The most complicated function of this commit is
calculateAllGroupGuideRates
which aggregates those individual contributions from the well (leaf)
level up to the root of the group tree (the FIELD group). This
process uses an ancillary array ('up') to keep track of the parent
groups of all wells and all groups, and to ensure that we only visit
each parent group once (sort+unique on subsets of the 'up' array).
We do not currently support outputting guiderates for reservoir
voidage volume (GuideRateModel::Target::RES).
This commit makes the 'groupData()' function return a
map<string, Opm::data::GroupData>
object instead of a
map<string, Opm::data::GroupConstraints>
object. The 'GroupData' structure adds a level of indirection to
the current per-group summary quantities that are directly assigned
by the simulator. While here, also move the assignment of the
current group constraints/control values out to a separate helper
to reduce the body of the per-group loop in 'groupData()'.
This is in preparation of adding support for reporting group-level
production/injection guiderates (Gx[IP]GR) to the summary file.
1) Only check GCONSALE limits at the end of a timestep. NB. The simulator still throws if some of the limits are violated
2) BUGFIX: don't remove gas consumption twice
- Communicate all well rates.
- When changing controls, modify rates to satisfy failed constraint.
- Ensure targets are positive.
- Always solve for potentials for MSW (temporary fix).
This PR remove the usage of well_control_ from opm-core
and instead uses the control classes for wells and groups
from opm-common.
This PR also removes the usage of the group classes from
opm-core.
