do you know your reservoir recovery methods= ?

Yogashri Pradhan is running a daily petroleum engineering prob= lem, and today's one is worth a shot. it's a tertiary recovery question, he= avy oil, steam injection. if you work in production or reservoir engineerin= g, this is your lane. go test yourself.

answer the question

name the method, explain why it works, or share a story from t= he field , any of those make the thread better.
