Seismic monitoring or 4D has started onshore on a few cases more than 30 years ago but has really developed over the last two decades, first in offshore fields where seismic image is generally of good quality, then onshore with more difficulties to achieve similar repeatability. In this presentation, several case studies of offshore and onshore 4D seismic form CGG’s experience are presented. The techniques used for monitoring, permanent or not, are adapted to the degree of complexity of the objectives and provide valuable support to reservoir engineers for tracking production related changes in the reservoir in order to economically optimize oil recovery. Although the economic objectives are often the same, production schemes and reservoir characteristics are different from case to case.
