Abstract

um método de detecção de um evento dentro de um furo de poço inclui obter um conjunto de dados de amostra, determinar uma pluralidade de características de domínio da frequência do conjunto de dados de amostra, comparar a pluralidade de características de domínio da frequência com uma assinatura de evento, determinar que a pluralidade de características de domínio da frequência corresponde aos limiares, intervalos, ou ambos das assinaturas de eventos, e determinar a presença do evento dentro do furo de poço com base na determinação de que a pluralidade de recursos de domínio da frequência corresponde aos limiares, intervalos, ou ambos da assinatura de evento. o conjunto de dados de amostra é uma amostra de um sinal acústico originário dentro de um furo de poço compreendendo um fluido, e o conjunto de dados de amostra é representativo do sinal acústico em um espectro de frequências. a assinatura de evento compreende uma pluralidade de limiares, intervalos, ou ambos correspondentes à pluralidade de características de domínio da frequência.
