Displacement Efficiency

Displacement efficiency measures how effectively a secondary recovery process pushes oil out of a reservoir. Imagine oil trapped in tiny pores underground; when an injection fluid (like water or gas) is introduced, it displaces the oil towards production wells. Displacement efficiency quantifies the proportion of that trapped oil successfully moved out compared to the total oil available. High displacement efficiency means the process effectively recovers more oil, while low efficiency indicates more oil remains unrecovered. It’s a key parameter for evaluating and optimizing enhanced oil recovery techniques.
