Abstract

''MéTODO E FLUIDO PARA REMOçãO DE REBOCO DE BROMATO/BROMO'' Trata-se de um método para remover o reboco de um poço não revestido subterrâneo que compreende a perfuração do poço não revestido com um fluido de perfuração que inclui aditivos para formar um reboco que tem um componente degradável por oxidação, de preferência um polissacarídeo. O reboco é colocado em contato com uma salmoura clara que contém agentes geradores de bromo ou bromato para degradar os polímeros dentro do reboco. A salmoura contém sais de brometo e um oxidante capaz de oxidação retardada do brometo em bromo em condições do fundo do poço.
