PROBLEM TO BE SOLVED: To provide a fracturing material that is hard to have an adverse effect on environment, and has little need of recovery and post treatment after fracturing.SOLUTION: A fracturing material is a slurry-like composition containing a base fluid and a proppant material which is a support material for supporting fracture and preventing the blockage thereof as essential ingredients. The fracturing material contains a biodegradable polyester resin, and the biodegradable polyester resin can be used as the proppant material which is the support material in the fracturing material. Also, the biodegradable polyester resin can be used as a friction reducing agent for reducing friction by forming the coating for coating the support material. Further, the biodegradable polyester resin can be used as a viscosity application agent to enhance the viscosity of the fracturing material. An aliphatic polyester resin synthesized from glycol and aliphatic dibasic acid can be used as the biodegradable polyester resin. |
