| titleOfInvention | COMPOSITION FOR CEMENTING WELLS AND THE METHOD OF ITS PREPARATION AND USE |
| abstract | A method for cementing a wellbore, comprising preparing a composition for cementing a wellbore containing cementitious materials and a modified biopolymer additive, where the modified biopolymer additive is a reaction product of the process, including contacting the biopolymer and organic carbonate to form a reaction mixture and exposing the reaction mixture to a temperature of about 100 ° F (38 ° C) to about 250 ° F (121 ° C), and the movement of the cementing solution for the wellbore into the wellbore. A method for cementing a wellbore, comprising contacting a modified biopolymer additive with a cementing solution to produce a composition for cementing a wellbore having an initial viscosity v; moving the composition for cementing the wellbore to the desired depth in the underground reservoir, where the composition for cementing the wellbore has an intermediate viscosity v at the time of transfer to the underground reservoir and the final viscosity v to the desired depth, where v≥v> v; and allowing the cementing compound to harden. |
