Abstract

"PROCESSO PARA A REDUçãO DA PRODUçãO DE áGUA EM POçOS DE PETRóLEO". é descrito um processo para redução da produção de água em poços de petróleo, com temperaturas de até (90<198>C), o qual compreende a injeção na formação em torno do poço de uma solução aquosa de um ou mais polímeros selecionados daqueles que possuem a fórmula geral (I) onde: n varia de (0,40) a (0,70), sendo de preferência de (0,5) a (0,65); m varia de (0,15) a (0,65), sendo de preferência de (0,3) a (0,5); p varia de (0,02) a (0,20), sendo de preferência de (0,05) a (0,10); n + m + p = 1; X~ 1~ é selecionado de H e CH~ 3~; R~ 1~, R~ 2~, iguais ou diferentes, são selecionados de grupos hidrocarbil monofuncionais C~ 1~-C~ 10~.
