Read data from Eclipse .DATA and run the simulation using MRST

[Cong Xiao]

Dear MRSTdeveloper, 

          I try to read data from Eclipse .DATA and run the simulation using MRST. However,  I encounter an error as floows:

           cannot identify  "W"。

Error  FacilityModel/validateModel ( 377 lines)
                W = varargin{1}.W;

Error   ReservoirModel/validateModel (213 lines)
        model.FacilityModel = model.FacilityModel.validateModel(varargin{:});

Error   ThreePhaseBlackOilModel/validateModel (207 line)
        model = validateModel@ReservoirModel(model, varargin{:});

Error   simulateScheduleAD (249 Line)
    model = model.validateModel(fstruct, opt.checkOperators);

Error   readDATA_new (60 line)
[wellSols, states, report] = simulateScheduleAD(state0, model, schedule);

I cannot read the schedule, however, the Well is not readed. Can you tell me which MRST function cann be used to read the well stucture from Eclipse DATA file for MRST simulation? I have attached the code. I'd appreciate it if you can help me.

best regard

Hi,

In general you'd use function 'initEclipseProblemAD' from the 'ad-core' module to load  your model from a ".DATA" file and then invoke function 'simulateScheduleAD' using the outputs that function, e.g,:

    [state0, model, schedule, nlsolver] = initEclipseProblemAD('CONTROL_OIL_2_1_1_1_1.DATA');

    [wellSols, state, report] = simulateScheduleAD(state0, model, schedule, 'NonlinearSolver', nlsolve)

You didn't share your run script, however, so maybe you're already doing this.  In that case there ought to be some other diagnostic messages, typically from the loading process, that might give you some additional clues as to the underlying issue.  Unless we know more about those we will not be able to provide any assistance.  As a general rule, we can't really aid you in any way unless we have at least the full run script and a complete copy of any diagnostic messages emitted while running it.

Hi Mr  Cong Xiao ,
when i upload the model ,this is the error ,how can i fix it ?

Hi,

Thank you for your interest in MRST. The diagnostic "Internal Logic Error" means that something's gone wrong while loading the input file and that we're in a situation that the parser did not expect and was not prepared to deal with. There can be any number of reasons for this, ranging from programming errors in the input loader, to faulty input that the loader was not able to identify. 

Without seeing the actual text/input it's unfortunately not easy to analyse the problem further. Would you be able to share the 'CASE_ADJUST_2_1.DATA' input file and any pertinent include files? If so, I can take a look and try to understand what's happening here. Otherwise, you may have to debug the problem yourself.

That said, I'd like to ask what MRST version you're running. We generally recommend getting the latest version—2025a at the time of writing (12 June 2025)—since that typically has the most up-to-date and tested code.

Best Regards,
