Paper Number: SPE-190737-MS
... is somewhat oversaturated (Saturation Ratio, SR >1) but the driving force is not sufficiently large and so the deposition is kinetically "slow". The industry response to this situation has been to come up with some simple heuristics based on field observations, and "rules of thumb" have been developed...

... It is worth noting that, although the saturation ratios for calcium carbonate are significant, the high supersaturation with respect to magnesium hydroxide could be the reason for the poor performance of the scale inhibitors previously investigated; inhibitors for this mineral are comparatively...

... surface at constant saturation ratio (SR) using a visualization flow rig. The effects of SR, flow rates and temperature on surface scaling were studied. Also, the influence of SR and inhibitor concentration on surface inhibition efficiency of Polyphosphinocarboxylic acid (PPCA) and diethylenetriamine...

Paper Number: SPE-130373-MS
... Abstract Phosphonate scale inhibitors (SIs) are commonly applied for barite scale prevention in oilfields. Their inhibition efficiency (IE) is affected by the barium sulphate saturation ratio (SR) of the brine mix as well as in the presence of divalent cations, Ca 2+ and Mg 2+ . What is less...

Paper presented at the SPE International Conference on Oilfield Scale, May 26–27, 2010
Paper Number: SPE-130374-MS
... Abstract In oilfield produced waters, the mineral scaling problem is a "moving target" since the seawater/formation water (SW/FW) mixing ratio is constantly changing. Therefore, for barium sulphate for example, the barite saturation ratio (SR), the yield of barite precipitate and molar ratio...

... conclusions of this work are: There is probably negligible formation damage arising from barium sulfate deposition in the near well bore region. There are three kinds of barium sulfate precipitation in the well depending upon the scaling tendency (saturation ratio) in the produced brine (it is assumed...

... Abstract Calcium carbonate scale is a common problem in the oil industry leading to reduced well performance and obstruction of the safety valves. Recent field experiences indicate that scaling may be a problem at lower Saturation Ratio (SR) than earlier anticipated. In a high pressure, high...
