Abstract

Métod y sistema destinado para el monitoreo sísmico de una zona subterránea (1) que comprende la utilizacion simultánea de varios vibradores sísmicos. Elsistema comprende, por ejemplo diversas unidades locales (LU) que comprende una un vibrador (5), una antena (2) una unidad de procesamiento y de adquisicionlocal (6), y una unidad de sincronizacion y de control central (8) para controlar de manera simultánea las diversas vibraciones por medios de senalesortogonales, siendo las unidades locales ( 6) adecuadas por medio de proceso particular, para aislar y reconstruir los sismogramas correspondientes a lascontribuciones de los diversos vibradores. Aplicaciones: monitoreo de un reservorio de hidrocarburos durante la produccion, o de un reservor io utilizado, porejemplo en el almacenamiento de gas.
