Abstract
The theoretical effect of barium on calcite crystal growth is widely discussed and investigated. This paper provides a broad analysis of the effect of barium on calcium carbonate scale using a dynamic scale loop (DSL). With a DSL, it is possible to simulate conditions that can be found in oil/gas pipelines in actual pressure and temperature conditions. The DSL measures with high accuracy, small variations in differential pressure over a 1mm/1m flow loop. This paper investigates three cases, simulated with and without barium additions, to provide futher understanding to the existing literature about the effect of barium on calcite scale growth. Effectiveness of scale inhibitors on these cases is also studied.
