Re: XAIRL in volume element with no liquid phase
Dear Youhanna, The non-zero XAIRL value you see in the output file for elements that do not have a liquid phase is just the equilibrium mass fraction (according to Henry's law) that would be present…

Re: Circulating same produced fluid

Re: Oil relative permeability in EOS8
T2VOC and EOS8 both have the properties of air. Three options: (1) Use TMVOC instead and specify CH4 as the NCG (2) Make changes to the EOS8 and/or T2VOC source code to replace air with CH4…

Re: Oil relative permeability in EOS8
Wendy, T2VOC and TMVOC are more accurate modules for simulating three-phase (aqueous, gas, oil) systems. You can pick appropriate chemical properties (in block CHEMP) to reduce or even prevent…

Re: Oil relative permeability in EOS8
Hi Wendy, Unfortunately, there is no flexibility in eos8.f to specify the oil relative permeability through user input. Instead, you have to go into the code and write your curve into function ak3…
