地震反射成像是一种地球物理方法，在深度上比其他方法提供更高的分辨率，因此是油气藏勘探的首选方法。然而，地震成像仅很少用于勘探和监测地热储层。然而，详细的储层图像是评估地热项目可行性和降低与昂贵的钻探计划相关的风险的必要先决条件。碳氢化合物地震成像的丰富经验在阐明改进地热储层地震勘探的途径方面有很大作用，但需要适应地热问题。在地热情况下具有巨大潜力的专门地震采集和处理技术是使用三维阵列和多分量传感器，加上复杂的处理，包括地震属性分析、偏振滤波/偏移、转换波处理和衍射波场分析。此外，全波形反演和S波分裂调查可能提供弹性参数的定量估计，从中可以推断关键的地热属性，如孔隙度和温度。
Seismic reflection imaging is a geophysical method that provides greater resolution at depth than other methods and is, therefore, the method of choice for hydrocarbon-reservoir exploration. However, seismic imaging has only sparingly been used to explore and monitor geothermal reservoirs. Yet, detailed images of reservoirs are an essential prerequisite to assess the feasibility of geothermal projects and to reduce the risk associated with expensive drilling programs. The vast experience of hydrocarbon seismic imaging has much to offer in illuminating the route toward improved seismic exploration of geothermal reservoirs — but adaptations to the geothermal problem are required. Specialized seismic acquisition and processing techniques with significant potential for the geothermal case are the use of 3D arrays and multicomponent sensors, coupled with sophisticated processing, including seismic attribute analysis, polarization filtering/migration, converted-wave processing, and the analysis of the diffracted wavefield. Furthermore, full-waveform inversion and S-wave splitting investigations potentially provide quantitative estimates of elastic parameters, from which it may be possible to infer critical geothermal properties, such as porosity and temperature.
