Abstract

"FLUIDOS DE POçO DE ESCAVAçãO DE PETRóLEO BASEADO NA áGUA". A invenção refere-se a fluidos de escavação de petróleo baseados em água usados durante um processo de recuperação de hidrocarbono, tal como a perfuração, o rompimento, o acondicionamento de cascalho e o trabalho total de escavação. De acordo com a presente invenção, tal fluido de escavação compreende um aditivo de perda de fluido e um material de suporte que são os hidrofóbicos in natura, os modificados hidrofobicamente ou os que ficam úmidos ao óleo. O fluido da escavação gera uma massa de filtro ativo que uma vez formada, é impermeável com relação a uma fase aquosa, reduzindo portanto a perda de fluido e assegurando um perigo reduzido para a formação, ainda que simultaneamente seja permeável ao escoamento reverso de hidrocarbonos durante um processo de recuperação do hidrocarbono.
