Abstract
A stabilized fracturing fluid and a method of stabilizing a fracturing fluid containing at least one of guar gum and a derivative thereof is disclosed, comprising adding at least one stabilizing compound selected from 2-mercaptobenzimidazole and 2-mercaptobenzothiazole compounds to the fracturing fluid. This stabilization prevents degradation of the fracturing fluid, i.e., reduction in its rheological properties at high temperatures and permits smoothly carrying out the fracturing operation.
