Abstract

Fremgangsmåte og blanding for bruk i forbindelse med boring, innføring av foringsrør og/ eller sementering av brønner i en underjordisk formasjon hvor det benyttes vannbaserte borevæsker. Borevæskene blir fortynnet eller dispergert med en blanding av kromfri ferrolignosulfonat og akrylat kopolymer med en eller flere akrylamido propansulfonat funksjonelle grupper ved en pH i området fra omtrent 8,0 til omtrent 10,5. Borevæskene inneholder ikke tungmetaller og er reologisk tolerante overfor forurensninger så som sement, anhydritt og natrium, samt ved temperaturer så høye som 177 °C.
