... of supply to fill the void will be from Enhanced Oil Recovery (EOR) techniques applied to existing fields. The current global ultimate average recovery factor for oilfields is roughly 35%. This means that about two-thirds of the already discovered oil is left within the reservoir. Pushing the recovery...

... Abstract Economically achievable oil recovery factors for offshore fields are typically lower than for similar onshore fields due to larger well spacing, inadequate reservoir characterization and shorter economic field life. The key challenge for mature offshore field development is to leverage...
