Pumpable geopolymers comprising a setting accelerator

摘要

The invention concerns the use of a carbohydrate-based compound as a setting accelerator in a pumpable geopolymeric suspension for oil and/or gas industry applications, said suspension further comprising an aluminosilicate source, a carrier fluid, and an activator, and methods of preparing such suspensions. In particular, the suspension according to the invention is used for well primary cementing operations and/or remedial applications.
