I’ve recently started exploring reservoir simulation using Eclipse, mainly looking at waterflood and gas injection scenarios. One thing that stands out early on is how much the accuracy of the results depends on history matching, which can be time-consuming and tricky.

For those with more experience in Eclipse or CMG — what have been your biggest challenges in running simulations for waterflood or EOR projects? And how did you manage them?

Would love to hear insights, tips, or even common mistakes to avoid as I continue learning.
