Abstract
Nouvelle composition d'un fluide de fracturation constitué de: 1) un polygalactomannane dérivé par carboxyalkyle présentant un degré de substitution compris entre environ 0,01 et environ 3,0; 2) un agent de réticulation sous la forme d'un sel de zirconium; 3) un ou plusieurs agents de stabilisation thermique, 4) un ou plusieurs tampons; et 5) de l'eau; ledit fluide étant capable de maintenir au moins 10 pour cent de sa viscosité de réticulation initiale après trois heures à une température supérieure ou égale à 250 DEG F.
