Abstract

"PROCESSOS PARA DEGRADAR UM SUBSTRATO PRé-DETERMINADO, UMA TORTA DE FILTRO E UM CONTAMINANTE EMERGINDO DE UMA FORMAçãO SUBTERRâNEA, PARA AUMENTAR O FLUXO DE HIDROCARBONETOS DE UM POçO E PARA TRATAR UM FURO DE POçO E COMPOSIçãO PARA USO EM OPERAçõES DE EXPLORAçãO DE HIDROCARBONETOS". São descritos processos e composições relacionadas para alterar as propriedades fisicas e químicas de um substrato usado em exploração de hidrocarbonetos, como em operações de perfuração de sondagem. Em uma forma de realização preferida, um processo envolve a formulação de um fluido, adequado às condições de perfuração específicas, que contém uma ou mais enzimas inativadas. Preferivelmente, a enzima é inativada por encapsulação em um material respondente a pH. Após o fluido ter sido introduzido no furo do poço, um ou mais sinais de disparo, como uma mudança no pH, é aplicado ao fluido que irá ativar ou reativar a enzima inativada, preferivelmente por uso da mesma para ser liberada pelo material de encapsulação. A enzima reativada é capaz de atuar seletivamente sobre um substrato localizado na sondagem para ocasionar a mudança desejada nas propriedades químicas ou fisicas do substrato.
