Hi everyone, Here at the Mexican Petroleum Institute our group is working on an enhanced oil recovery (EOR) problem, as mentioned below. Among several alternatives for implementing our model, the Dune-DuMux computing platform has caught our attention and we have been working into understanding the code and design philosophy.
The problem at hand is the simulation of low- salinity water injection (LSWI) in carbonated fields, for which several two phase examples based on the tutorial and the code in the "dumux/test" directory have been implemented; but due to the compositional fluid state with chemical reactions required, a deeper understanding of the code is necessary. The main issue is how to define a two-phase compositional oil-brine system, where the brine is composed of multiple ions and reactions are allowed between them. Working with the 2p model, and changing the fluid state from immiscible to compositional, has led to modifications in the model, although this has not born results as of yet. Switching to the 2pncmin model and replacing the fluid system from air/brine to an oil/brine composition has also encountered some issues. The 2pnc constraint solver has been modified to ensure no migration of components from one phase to another, but fugacity coefficients seem to be causing problems, apparently within the fluid state. What would be the best strategy you would recommend to follow? Building up from the 2pnc model? Working down from the 2pncmin model? Maybe eliminating the gas phase from the 3pwateroil model? Any suggestions or pointers to examples would be greatly appreciated.
