Improve debugging tools in gaslift code. Introduces a gaslift debugging variable in ALQState in WellState. This variable will persist between timesteps in contrast to when debugging variables are defined in GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2. Currently only an integer variable debug_counter is added to ALQState, which can be used as follows: First debugging is switched on globally for BlackOilWellModel, GasLiftSingleWell, GasLiftGroupState, and GasLiftStage2 by setting glift_debug to a true value in BlackOilWellModelGeneric. Then, the following debugging code can be added to e.g. one of GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2 : auto count = debugUpdateGlobalCounter_(); if (count == some_integer) { displayDebugMessage_("stop here"); } Here, the integer "some_integer" is determined typically by looking at the debugging output of a previous run. This can be done since the call to debugUpdateGlobalCounter_() will print out the current value of the counter and then increment the counter by one. And it will be easy to recognize these values in the debug ouput. If you find a place in the output that looks suspect, just take a note of the counter value in the output around that point and insert the value for "some_integer", then after recompiling the code with the desired value for "some_integer", it is now easy to set a breakpoint in GDB at the line displayDebugMessage_("stop here"). shown in the above snippet. This should improve the ability to quickly to set a breakpoint in GDB around at a given time and point in the simulation.

Change condition under which stage 2 is done. It only makes sense to try to optimize the distribution of lift gas if the amount of lift gas is constrained either by the maximum allowed gaslift or total gas or the group is under individual control.

Also fixes a typo (as discussed in PR #3729) in reduceALQtoGrouptTarget() where the water rate is updated with the gas flow rate instead of the water flow rate. Should be like this: water_rate = -potentials[this->parent.water_pos_]; instead of water_rate = -potentials[this->parent.gas_pos_];

Well testing of gas lift wells Assign a maximum ALQ value to each GLIFT producer when doing well testing in beginTimeStep(). This allows the well to be considered open. Then, later in the timestep, when assemble() is called, the full gas lift optimization procedure can adjust the ALQ to its correct value. It is also observed that in some cases when gas lift is switched off by setting ALQ to zero, and later in the schedule is switched back on again, it might not be possible to determine bhp from thp for low small ALQ values. Instead of aborting the gas lift optimization, we should try increasing ALQ until we get convergence or until the maximum ALQ for the well is reached.

This variable will persist between timesteps in contrast to when debugging variables are defined in GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2. Currently only an integer variable debug_counter is added to ALQState, which can be used as follows: First debugging is switched on globally for BlackOilWellModel, GasLiftSingleWell, GasLiftGroupState, and GasLiftStage2 by setting glift_debug to a true value in BlackOilWellModelGeneric. Then, the following debugging code can be added to e.g. one of GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2 : auto count = debugUpdateGlobalCounter_(); if (count == some_integer) { displayDebugMessage_("stop here"); } Here, the integer "some_integer" is determined typically by looking at the debugging output of a previous run. This can be done since the call to debugUpdateGlobalCounter_() will print out the current value of the counter and then increment the counter by one. And it will be easy to recognize these values in the debug ouput. If you find a place in the output that looks suspect, just take a note of the counter value in the output around that point and insert the value for "some_integer", then after recompiling the code with the desired value for "some_integer", it is now easy to set a breakpoint in GDB at the line displayDebugMessage_("stop here"). shown in the above snippet. This should improve the ability to quickly to set a breakpoint in GDB around at a given time and point in the simulation.

Well testing of gas lift wells Assign a maximum ALQ value to each GLIFT producer when doing well testing in beginTimeStep(). This allows the well to be considered open. Then, later in the timestep, when assemble() is called, the full gas lift optimization procedure can adjust the ALQ to its correct value. It is also observed that in some cases when gas lift is switched off by setting ALQ to zero, and later in the schedule is switched back on again, it might not be possible to determine bhp from thp for low small ALQ values. Instead of aborting the gas lift optimization, we should try increasing ALQ until we get convergence or until the maximum ALQ for the well is reached.
