<p>The invention relates to a method for detecting of changes of a fluid in a subterranean reservoir, wherein at several points in time, data (1) are collected with the aid of a passive method in which low-frequency acoustic signals are passively measured by means of acoustic sensors (10). Changes in the fluid can be monitored in a simple and cost efficient way when these data are overlaid with static 3D data (2), which were collected with the aid of a reflection-seismic method so that a time-related representation of the change of the fluid is possible.</p> |
