<p>PROBLEM TO BE SOLVED: To provide a viscosity adjusting agent which has viscosity characteristics equal to those of the guar gum to be used as the conventional viscosity adjusting agent, is used regardless of cutting sludge or components used in a fracturing fluid, is excellent in homogeneous dispersibility of a proppant, transportability and heat resistance, and is capable of being supplied more stably in comparison with the guar gum, and to provide the fracturing fluid obtained by using the viscosity adjusting agent.SOLUTION: The viscosity adjusting agent contains at least one selected from locust bean gum (A) and guar gum (B), and xanthan gum (C) by 1:99 to 99:1 of a mass ratio of (the total mass of the component (A) and the component (B)):(the mass of the component (C)).</p> |
