    摘要: Barium sulfate and/or calcium carbonate scale inhibitor composition 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 sulfonate monomer, or a mixture thereof. The scale inhibitor composition can be used as a means of detecting inhibitor composition in downhole and topside oilfield treatments by means that are faster and more accurate than turbidometric measurement.

    摘要: Methods of controlling barium sulfate scale in oil field applications are disclosed. These methods involve the application of one or more carboxylated oligomers to an aqueous system in the oil field. Carboxylated oligomers include polymaleic acid and polyethercarboxylates. Additionally, methods of neutralizing polymaleic acid and use of this neutralized product for barium sulfate scale control are disclosed.
