有效的储层监视和监测技术应能够监测储层流体的变化，并更好地了解流体随时间的空间运动和分布。不幸的是，传统的监测和监视方法无法提供详细的信息。需要这种类型的知识来支持由4D地震技术提供的合理的储层管理和油田开发决策。近年来，随着地震采集和处理技术的进步，四维地震技术在油气田勘探中的应用越来越广泛，本文综述了四维地震技术在延长油气田寿命和提高油气采收率方面的应用，并着重介绍了近几十年来四维地震技术的进展。讨论了地下二氧化碳（CO2）封存点的监测问题、四维地震技术与其他地球物理方法的结合以及非常规油气藏四维地震监测需求的增长等发展现状和挑战。此外，对已发表的研究进行了批判性的回顾，认为四维地震方法可以用于非常规油藏的油藏动态监测。然而，4D技术在该地区的成功是基于多学科的方法，其中4D地震技术与地质力学和流体流动相结合。然而，所有这些工作流程都依赖于岩石物理建模，目前可用的大多数岩石物理模型都与一些不确定性有关。此外，由于与孔隙尺度变化相关的不确定性，在注入过程中准确监测CO2的能力仍然是一个挑战。一些研究强调，使用其他地球物理方法，如源控电磁（CSEM），重力和地表变形监测目的在油气藏和储存是可行的。然而，在文献中仍然有一些差距，这些技术与四维地震的整合。综合利用地球物理方法是今后油气藏监测的发展方向。
An efficient reservoir surveillance and monitoring technique should be able to monitor changes in the reservoir fluid and provide a better understanding of the spatial movement and distribution of fluids over time. Unfortunately, traditional methods of monitoring and surveillance are unable to provide the detailed pieces of information. This type of knowledge is needed to support the rational reservoir management and field development decisions provided by 4D seismic technology. With recent technological advances in seismic acquisition and processing, the case for its application has been strengthened.This article, therefore, reviewed the application of 4D seismic technology in extending the life of hydrocarbon fields and improving hydrocarbon recovery, with specific consideration to the progresses made over the last decades. It also discussed the current status of developments and challenges, including monitoring issues related to subsurface carbon dioxide (CO2) storage sites, integrating 4D seismic technology with other geophysical approaches, and the growing need to monitor 4D seismic in unconventional reservoirs.Most researches emphasized that useful conclusions can be drawn by using a combination of seismic attributes instead of using them alone. Furthermore, the critical review on the published researches suggested that the 4D seismic method can be used for dynamic reservoir monitoring in the unconventional reservoir. However, the success of 4D technology in this area is based on a multi-disciplinary approach where the 4D seismic technology is integrated with geomechanics and fluid flow.Although, the review demonstrated that 4D seismic technology was used in the history matching process. However, all these workflows depend on rock physics modeling and most of the rock-physics models currently available are associated with some uncertainties. In addition, the ability to accurately monitor a CO2during injection remains a challenge due to uncertainties associated with pore-scale variations. Several studies have highlighted that the use of other geophysical methods such as source-controlled electromagnetic (CSEM), gravity, and surface deformation for monitoring purposes in hydrocarbon reservoirs and storage is feasible. However, there are still several gaps in the literature regarding the integration of these techniques with 4D seismic. An integrated use of geophysical methods is the future direction of reservoir monitoring and surveillance from existing fields.
