EOS3-sink/source rates are piecewise constant, how to set up?
As mentioned in the title, I want to set the piecewise constant sink/source rate as shown in the attached figure, but I can't achieve the desired result after setting it many times in petrasim, can anyone give me some help, I am very eager to know how to set this step?Thank you very much!
if you want to use the Wells option in Petrasim, you need to assign the variable production and injection schedule in the Wells/flow window by assigning times-rates for the production and time-rates-enthalpy for the injection periods :
- production \ mass out \ Rate = Table : assign time-rates schedule
- injection \ water/steam \ Rate = table : assign time-rate-enthalpy schedule.
In order to exactly reproduce your production/injection schedule, it is better to use the Rigorous step option under "solution control\options\MOP(12)".
In addition, better to set optional printout at the times corresponding to rate changes. In this way there will be no interpolation during time steps including a rate change.
You can view the results under Results\Well plots, where you will find 1 sink (MASS) and 1 source (COM1). Results are saved in file GOFT. Of course you have to request the printout under Wells\print options.
Take the attached Petrasim file as an example of the above choices (Petrasim 2020.2.1222 x64).
