Abstract

La presente invención proporciona un sistema de monitoreo sísmico basado en fibra óptico que incluye una fuente de luz que conduce una fibra óptica a ubicarse dentro de una perforación de pozo. Por lo menos un sensor de luz analiza la dispersión de retorno Rayleigh para obtener una señal acústica por cada uno de los puntos múltiples a lo largo de la perforación de pozo. Uno o más procesadores operan para determinar la dirección, distancia y/o intensidad del evento microsísmico con base en, por lo menos, una parte de la información de fase de dichas señales acústicas. Se pueden determinar las medidas de las correlaciones cruzadas de la señal acústica, las semblanzas o la similitud de fase sensible como una función de la dirección de escaneo para determinar exactamente la información del evento microsísmico. La fibra óptica se puede posicionar en el espacio anular cementado de una perforación de pozo revestida que tiene una forma que se extiende a lo largo de más de una dimensión (por ejemplo, una perforación de pozo en forma de L).
