Scale control composition |
| abstract |
A barium sulfate and/or calcium carbonate scale inhibitor composition is presented composed of a water-soluble polymer having incorporated phosphate functionality, the polymer being formed from at least one ethylenically unsaturated carboxylic acid monomer, at least one ethylenically unsaturated vinyl sulphonate monomer, or a mixture thereof. The scale inhibitor composition can also be used as a means of detecting the inhibitor composition in downhole and topside oilfield treatments by means that are faster and more accurate than turbidometric measurement. |
