Zirconium-based cross-linker compositions and their use in high ph oil field applications |
| abstract |
A cross-linking composition which comprises (a) an aqueous liquid, (b) a cross-linkable organic polymer, and (c) a solution comprising a zirconium cross-linking agent which comprises a zirconium complex having a molar ratio of 1:2 to 1:4 of zirconium to triethanolamine and a molar ratio of 1:0.1 to 1:1 of zirconium to N,N,N,N -tetrakis-(2-hydroxypropyl)-ethylene diamine. The composition can be used in oil field applications for hydraulic fracturing and plugging of permeable zones and leaks in subterranean formations. |
