Paper presented at the SPE Formation Damage Control Symposium, February 26–27, 1992
Paper Number: SPE-23814-MS
.... It is therefore important to have a proper understanding of the kinetics of scale formation and its detrimental effect on formation damage under both inhibited and uninhibited environment. In this paper, we will present results of BaSO4 formation kinetics in both beaker tests and in highly reproducible sandpacks...

... serious operational problem in the production of oil. Often, seawater is injected into a reservoir containing soluble barium in its connate water. When seawater breakthrough occurs, BaSO4 scale can form downhole in the near wellbore area and production tubulars as well as in the topside, crude oil...
