Compositions and method for well cementing

Organic compounds containing at least one nitrogen atom are particularly suitable as retarders for geopolymeric systems employed as well cements. Preferred compounds include aminated polymers, amine phosphonates, quaternary ammonium compounds and tertiary amines. The geopolymeric compositions are su...

More Information
Summary:Organic compounds containing at least one nitrogen atom are particularly suitable as retarders for geopolymeric systems employed as well cements. Preferred compounds include aminated polymers, amine phosphonates, quaternary ammonium compounds and tertiary amines. The geopolymeric compositions are suitable for primary cementing and remedial cementing operations. The preferred temperature range within which the retarders operate is between about 20°C and 120°C.
