A24 Impact of Brine Chemistry on Oil Recovery A. Lager* (BP) K.J. Webb (BP) & C.J.J. Black (BP) SUMMARY Since its accidental discovery at the beginning of the 20th century waterflooding has become the most successful form of oil rcovery and the vast majority of oil fields without an active aquifer or with a partial water drive are or will be under waterflood. Waterflooding is considered by the majority of reservoir engineers as a technique for pressure maintenance to energise the reservoir and as such the majority of waterflooding research has been conducted on fluid mechanics and the physics behind
