Abstract

"MéTODOS PARA PERFURAR E COMPLETAR UMA PERFURAçãO DE POçO DE FURO ABERTO, E PARA REMOçãO DA TORTA DE FILTRAçãO COMPOSTA DE UM AGENTE GELEIFICANTE E CARBONATO DE CáLCIO DAS PAREDES DE UMA PERFURAçãO DE POçO DE FURO ABERTO". São proporcionados métodos para perfurar e completar perfurações de poços de furo aberto e métodos para a remoção de torta de filtração composta de um agente geleificante e carbonato de cálcio. Um método da invenção para a remoção da torta de filtração, composta de um agente geleificante e de carbonato de cálcio, das paredes da perfuração de poço com furo aberto, é composto basicamente das etapas de colocar em contato a torta de filtração com uma solução de limpeza retardada composta de água e um éster de formato e remover essa solução de limpeza da perfuração do poço.
