Method of stimulating subterranean formation using low ph fluid |
| abstract |
Hydraulic fracturing is conducted by use of a well treatment fluid which contains a guar gum derivative as viscosifying or gelling polymer, an organic zirconate complex of a zirconium metal and an alkanol amine as crosslinking agent and a hydroxylated glycine or a salt thereof as crosslinking delaying agent. The fluid is characterized by a low pH, generally greater than or equal to 3.0 and less than or equal to 5.0. |
