Paper Number: SPE-195326-MS
... in the production wells, particularly at initial breakthrough of the waterflood front [ Meyers 1985 ]. The injected seawater is rich in sulfate and the connate water is rich in barium which leads to the severe scaling problems. The first waterflood water to reach the producing well typically has the highest scaling...

While producing through horizontal wells there is always a possibility of breakthrough of unwanted water or gas compromising the production of oil and to some extent leaving some valuable oil reservers behind. The reason behind this is that the heel of the well produces at higher rate than the toe...

Thinner oil leads to bottom water invading oil around the toe after breakthrough...
