Abstract
La presente invención proporciona un sistema de monitoreo sísmico de fibra óptica que incluye una fuente de luz que activa una fibra óptica colocada dentro de un pozo de sondeo. Al menos un sensor de luz que analiza luz de retrodispersión de Rayleigh para obtener una señal acústica para cada uno de los múltiples puntos a lo largo del pozo de sondeo. Uno o más procesadores operan para determinar la dirección, distancia, y/o intensidad del evento microsísmico basado al menos en parte en la información de fase de las señales acústicas. Las medidas de correlación cruzada, semblanzas o similitud de sensibilidad de fase de las señales acústicas pueden determinarse como una función de una dirección de escaneo para determinar de forma precisa la información del evento microsísmico relevante. La fibra óptica puede colocarse en la zona anular cementada de un pozo de sondeo revestido que tiene una forma que se extiende a lo largo de más de una dimensión (por ejemplo, un pozo de sondeo en forma de L).
