Can I set CO2 property constant in PetraSim?

Hi, everyone:

I would like to do a simulation under ECO2N with the assumption that the CO2 property will stay constant as it comes from a geographically deeper layer to a shallower one. Is there a way to set the property as constant in PetraSim?

Thanks.

John

John,

You can accomplish this by generating your own CO2TAB file. Proceed by analogy to the CO2TAB file that comes with ECO2N. You can define just two temperatures and two pressures, one low the other high, to cover the range of T,P-conditions you need. Then enter by hand the desired values for CO2 density, viscosity, and specific enthalpy, making them the same for all of the T,P-conditions. The READ.ME file that comes with ECO2N has more info on the formats for the CO2TAB file.
