Method of recycling fracturing fluids using a self-degrading foaming composition |
| abstract |
A method of fracturing a subterranean zone penetrated by a well bore by preparing a foamed fracturing fluid containing a self-degrading foaming composition comprised of a mixture of anionic surfactant and nonionic surfactant. The fracturing fluid containing a self-degrading foaming composition forms a substantially less stable foam when the foamed fracturing fluid is recovered during reclaim. |
