Time-shift, one of the most popular time-lapse seismic attributes, has been widely used in dynamic reservoir characterization by linking it with pressure and geomechanical changes. Therefore, it is important to select appropriate calculation methods according to different time-lapse seismic data quality and time-shift magnitude. To date, there have been various published works comparing different time-shift calculation methods and discussing their advantages and disadvantages. However, most of these comparisons are based only on synthetic tests or single field applications. As the quality of time-lapse seismic data and time-shift magnitude can vary in different fields, one method may not work consistently well for each case. In this paper, a critical comparison of three different time-shift calculation techniques (Hale’s fast cross-correlation, Rickett’s non-linear inversion, and Whitcombe’s correlated leakage method) is provided. The three methods are applied to a set of synthetic data sets that are designed to account for various seismic noise and time-shift magnitudes. They are also applied to four real time-lapse seismic data sets from three North Sea fields. The calculated time-shift results are compared with the input (in synthetic tests) or the real observations from information such as seabed subsidence and compaction (in field applications). Both qualitative and quantitative comparisons are performed. At the end, each of the time-shift methods is evaluated based on different aspects, and the most appropriate method is suggested for each data scenario. All three time-shift methods are found to successfully measure time-shifts. However, Rickett’s non-linear inversion is the most outstanding method, as it gives smooth time-shifts with relatively good accuracy, and the derived time strains are more stable and interpretable.

时移是最流行的时移地震属性之一，通过将其与压力和地质力学变化联系起来，已被广泛用于动态油藏表征。因此，重要的是要根据不同的时移地震数据质量和时移幅度选择合适的计算方法。迄今为止，已经有各种发表的作品比较了不同的时移计算方法并讨论了它们的优缺点。但是，大多数比较仅基于综合测试或单一领域的应用。由于时移地震数据的质量和时移幅度在不同领域可能会有所不同，因此一种方法在每种情况下可能无法始终如一地发挥作用。本文主要对三种不同的时移计算技术（Hale的快速互相关，提供了Rickett的非线性反演和Whitcombe的相关泄漏法。这三种方法应用于一组综合数据集，这些数据集旨在解决各种地震噪声和时移幅度。它们还应用于来自三个北海油田的四个实时延时地震数据集。将计算出的时移结果与输入（在合成测试中）或来自诸如海床沉陷和压实等信息（在现场应用中）的实际观测值进行比较。进行定性和定量比较。最后，将基于不同方面评估每种时移方法，并针对每种数据场景建议最合适的方法。发现所有三种时移方法都可以成功地测量时移。然而，
