The Nature of Naturally Fractured Reservoirs

摘要

Naturally fractured reservoirs present a production paradox.They include reservoirs with low hydrocarbon recovery:these reservoirs initially may appear highly productive,only to decline rapidly.They are also notorious for early gas or water breakthrough.On the other hand,they represent some of the largest,most productive reservoirs on Earth.The paradoxical nature of this class of reservoirs is the impetus behind the industry's efforts to learn more about them and model them with a reasonable amount of certainty.
