Abstract
<B>PROCESSO DE RECUPERAçãO SECUNDáRIA DE PETRóLEO COM INJEçãO DE áGUA TRATADA<D> é descrito um processo de recuperação secundária de petróleo com injeção de água tratada que compreende a precipitação prévia e controlada das espécies químicas precursores de precipitação presentes na água de injeção ou água do mar e água de formação ou água produzida, seguida de remoção dessas espécies por filtração. A água tratada obtida apresenta baixos teores de íons precursores de precipitação e é perfeitamente adequada para uso como água de injeção em processos de recuperação secundária de petróleo. Por utilizar grandes volumes de água produzida, o processo é de grande interesse ambiental, já que preserva o ambiente marinho do descarte de água produzida altamente salina. Os equipamentos utilizados no processo são relativamente simples e de baixo custo.
