Abstract

Fremgangsmåte for forbedret nedbryting av metall- tverrbundede polymergeDer som er nyttige i olje- og gassbrønnbehandlingsoperasjoner. I fremgangsmåte blir en forestret karboksylert chelator tilsatt gelen. Ved forhøyede temperaturer, gjennomgår den forestrede chelatoren hydrolyse for å danne en syre og en aktiv ligand som deretter fjerner tverrbindlngsmetallionet fra gelen og hydrolyserer polymeren.
