Abstract

See full text

A fracturing fluid viscosity-controlling agent maintains the high viscosity of the fracturing fluid during fracture formation in hydraulic fracturing and reduces the viscosity during recovery of the fracturing fluid. A fracturing fluid which includes the viscosity-controlling agent is provided as well as a crude oil or natural gas drilling method using the fracturing fluid with the viscosity-controlling agent. This viscosity-controlling agent contains polyalkylene oxide and a viscosity-reducing agent and is in the form of a tablet.
