While the global oil industry is frantically trying to coax the last stubborn drops from mature fields with everything from polymer cocktails to CO2, it’s clear our technological ingenuity is matched only by our continued dependence on the very resource we’re scouring the planet to recover.

Technological Advancements Interpretation

Even though each method plays a different instrument, the global EOR orchestra is finally harmonizing, conducting a clever and diversified encore to squeeze the concert hall of mature reservoirs for every last valuable drop.
