I would appreciate any guidance on the this.
I have mixed two different waters (1/1) under atmospheric conditions; the first is highly saline and the second is less saline.
I would then like to speciate the mixed water (above) under reservoir conditions - pressure of 3500kPa. Methane comprises more than 97% of the gas phase in the reservoir.
When I add CH4 under "Basis" at 3.5MPa (3500kPa), and run the speciation program, the program informs that O2 (aq) needs to be constrained in the basis entry for fluid "initial".
When I add 0.001 mg/L O2(aq), the program fails to converge after 999 iterations.
Any thoughts on what needs to be done to get the program to converge?
Thanks,
Bob
