[Opm] FW: [Help] Convergence issues - FLOW

[Nair, R. (Rohith)]

Dear OPM community,

At the recently held OPM meeting I had mentioned that we at TNO are facing convergence issues with FLOW when using perturbed schedule files and also with handling well openings (Note: ECLIPSE is able to deal with these perturbed schedule files). I believe it was mentioned that you guys were already working towards a fix for these sort of issues. We would appreciate your help/suggestions/workarounds in solving these convergence issues and ultimately improving the robustness of the FLOW simulator in the process.

Please find the relevant data available for download from the following link: https://we.tl/OBTYWPLnwg

The download contains:


1.       Failed simulation with FLOW for simple water injection rate optimization (successful simulation is also included): The only difference between the successful and failed simulation is different water injection rates

2.       Failed simulation where wells are opened at predefined intervals

3.       Benchmark plots which successfully compare FLOW with other simulators(E100, MRST, Mores, AD-GPRS) for oil-water flow simulation

Thanks and Kind regards,
Rohith Nair
