Abstract

resumo “prevenção de formação de lama durante procedimentos de acidificação” a presente invenção proporciona composições químicas úteis para minimi-zar ou prevenir a precipitação de lamas, tais como asfaltenos, maltenos, ou compo-nentes asfálticos semelhantes, durante um tratamento de acidificação. os métodos para prevenir ou minimizar a formação de lamas são também descritos. as composi-ções antilamas podem ser adicionadas a uma solução ácida aquosa antes de injetar a solução dentro de um poço para tratamento. as composições podem incluir um ácido dodecilbenzeno sulfônico formulado, um tensoativo catiônico, um agente ini-bidor da corrosão, e um agente de redução de ferro, em adição aos outros aditivos.
