• Re: Multilayer well screen simulation

    Thank you Peter,
    I'll try to make some tests, maybe exaggerating the well screen length and placing the pump at the top of the screened interval; I'd like to verify the results in term of contaminant plume interception at different depths.
    It would be very nice to have the same advanced level of simulation (and interface) available in Feflow for BHE (well construction details, materials, filter pack, geometry and so on) also for standard extraction and injection wells; for example, it should help to verify the real efficiency of a P&T system in a small scale model.

    Another related (and interesting) issue would be how to simulate the effective pumping depth along the well screen. The pump is not always placed in the lowest node of the simulated vertical...
  • Multilayer well screen simulation

    Hello,
    I've got a question about simulating well screens with Multilayer Well Boundary Condition.

    I need to simulate pumping and reinjection wells at different depths inside a multilayered model domain and I'm actually assigning the MW boundary condition only to layers that effectively correspond to the well screen (5 to 20 meters long, starting from the bottom of the well) and not to the entire well bore depth (sometimes 5 to 10 times longer).
    This way the upper vertical, containing the rest of the (non screened) well casing, is not considered at all in the flow simulation.

    Is this the best way to simulate multilayer wells with short well screens?
    Should I try instead to consider also the well casing and the disturbed zone around the well or the effects will be negligible in medium to large scale models?

    Thank you!

    Thank you for the quick answer.
    Sorry, I used a wrong word, the term "crash" is inappropriate for this case.
    I should use "freeze" instead.
    It's not a typical crash with bug reports, etc., the problem is that my computer doesn't respond to the right click command and after that, it does not respond to any input at all, so then I have to call task manager and quit Feflow.
    The hardware acceleration trick is not working.
    As soon as possible I'll try to update my graphic card driver.
    Thank you again
  • Crash in Feflow 6.2 (p8) on a Windows 7 PC - Right click on charts

    Hello,
    I'm experiencing several crashes after right-clicking on hydraulic head/temperature charts, in order to export parameter trends.
    After a simulation run I'd like to save the results of calculated data-series in different observation points and most of the times (for long period simulations in particular) my PC crashes.
    Any idea about possible solutions/workarounds?
    Thanks
