Leaking amount

[Jon Liu]

Hi all, anyone help about large leaking after 10 years simulation? The model size is 60km by 60km with three injection wells in center. Thanks!

[init.wellSols, init.states] = simulateScheduleAD(initState, model, schedule,'NonLinearSolver', NonLinearSolver('useRelaxation', true));

Total injected: 94669779.163276 (m3)
Total leaked (by infinity): 24425648.542147 (m3)
Penalty: 5.000000
Score: -27458463.547457 (m3)

Hi,

What simulation is this? As long as the leakage is below 100%  (25%  in this case) it is hard to say if there is to help you with since this could be what your setup implies. Can you explain more about your issue?

Best regards,

Olav

Thanks Olav,   this is CO2 injection simulation. The injection period is 10, and 30 years migration, but looks too much leaking after 40 years..   I found using smaller cell size will reduce the leaky amount a lot (from 200x160 to 400x320, 60km). Still debugging..

 

Best,

Jon
