A comprehensive experimental study on the mechanisms of waterflood inefficiency in a Morrowan sandstone reservoir.

An indispensable factor in developing improved enhanced oil recovery (EOR) is the in-depth insight into the fractional flow mechanistic effects of waterflood performance, especially for an inefficient waterflood operated field. In this study, the inefficiency of waterflood on the Farnsworth Field Unit (FWU) is investigated. The field is divided into two halves (East and West) of the same reservoir with similar geological characteristics.
