Thermally responsive aqueous silicate mixture |
| abstract |
Sealing a zone in a subterranean well-formation is affected with an aqueous silicate solution containing an alkali metal silicate, at least one activator and a mixture of a chelating agent and a phosphonate. This composition greatly increases the divalent ion tolerance of the silicate gelling system. |
