Abstract
Official abstract text for this publication.
A method of scale inhibition treatment of a water system comprising introducing an aqueous scale inhibiting composition into the water system wherein the aqueous scale inhibiting composition comprises a carboxylated hyperbranched polyglycerol.
First claim
Opening claim text (preview).
We claim: 1. A method of scale inhibition treatment of a water system used in oil and gas well applications and industrial water treatment comprising introducing an aqueous scale inhibiting composition into the water system wherein the aqueous scale inhibiting composition comprises a carboxylated hyperbranched polyglycerol polymer having a chemical formula 2. The method of claim 1 wherein the polymer concentration ranges 1-60 wt % in said aqueous scale inhibiting compositions. 3. The method of claim 1 wherein said polymer has molecular weight of about 1,000 Da to 50,000 Da. 4. The method of claim 1 , wherein the aqueous scale inhibiting composition is used in an aqueous environment having a temperature ranging from about 20° to 300° C. 5. The method of claim 1 , wherein the aqueous scale inhibiting composition is used in an aqueous environment having total dissolved solids ranging from about 2000 to 400,000 tds. 6. The method of claim 1 , wherein the aqueous scale inhibitors composition is used in an aqueous environment having a pH ranging from about 4 to 8.
