Wellbore cementing compositions and methods of making and using same |
abstract |
A method of cementing a wellbore comprising preparing a wellbore cementing composition comprising a cementitious materials and a modified biopolymer additive wherein the modified biopolymer additive is the reaction product of a process comprising contacting a biopolymer and an organic carbonate to form a reaction mixture and subjecting the reaction mixture to a temperature of from about 100 °F (38°C) to about 250 °F (121°C) and placing the wellbore cementing fluid in the wellbore. A method of cementing a wellbore comprising contacting a modified biopolymer additive with a cementitious slurry to produce a wellbore cementing composition having an initial viscosity, v |
