摘要：
Methods for temporary fracture isolation are provided. An existing fracture is treated with a chemical diverter. The chemical diverter is exposed to conditions causing it to expand, plugging the fracture. A new fracture can be created through the application of pressure and fluid, without disrupting the plugged fracture. The chemical diverter can then be removed through biodegradation or the application of a solvent to reopen the first fracture.
