Abstract

"MéTODO EM TEMPO REAL PARA A MANUTENçãO DA ESTABILIDADE DE UMA FORMAçãO SUBTERRâNEA". Um método em tempo real é mostrado, para a manutenção da estabilidade de uma formação subterrânea, através da monitoração da interação entre a formação e os fluídos introduzidos em (ou produzidos a partir de) um furo de poço que penetra na formação. O método emprega uma metodologia de registro de eventos de (instabilidade) estabilidade de furo de poço em tempo real. O método é exemplificado por um teste de Transmissão de Poropressão (PPT). Nesse teste, os fluidos de teste são expostos a folhelhos Pierre II (20 % w/w de solução de NaC1 e fluido de silicato de sódio com 20% w/w de NaC1, por exemplo) em um aparelho de PPT. A eficiência da membrana dos dois fluidos, quando exposta ao folhelho de afloramento é calculada, e com base na aquisição simultânea de dados acústicos, uma estimativa de uma propriedade dinâmica de rocha é feita. A calibração da resposta do núcleo do folhelho representativo (ou de uma outra formação) a fluidos de perfuração (ou fluidos de serviço de poço, fluidos de recuperação melhorada, ou fluidos de produção), sob condições realísticas in situ, auxilia na modelagem acurada para uma (instabilidade) estabilidade da formação dependente do tempo no campo, para toda a vida do furo de poço, desde a perfuração, a completação e durante a perfuração.
