You might spell the words "enhanced oil recovery", which will allow interested readers to look for more info. There is nothing in common between water injection, renown technology which has been around for decades, currently producing millions bbl/d, and the flame front which is hardly an idea, issued two decades ago and never produced a barrel. Many other EOR technologies are currently in use.

I did use the phrase "enhanced oil recovery", although people might not notice it.

There is a new version of the flame front "Toe to Heel Air injection" which is in testing stages, and seems to have some promise. Petrobank in Canada is working on this, and claims some success.
