一个典型的小规模地震测量（如240炮集）至少需要16个工作小时才能完成，这是延时监测实验的一个主要障碍。如果需要监测的对象正在迅速变化，则尤其如此。在这项工作中，我们将讨论如何减少记录时间从16个工作小时到不到一个小时的记录。这里，虚拟数据具有与传统数据相同的精度。我们验证了简约的地震干涉测量的效果与时间推移的指导思想与现场的例子，在那里我们能够记录30个不同的数据集在2小时内。记录的数据然后被处理，以生成30个快照，显示水从地面向下蔓延到几米。
A typical small-scale seismic survey (such as 240 shot gathers) takes at least 16 working hours to be completed, which is a major obstacle in case of time-lapse monitoring experiments. This is especially true if the subject that needs to be monitored is rapidly changing. In this work, we will discuss how to decrease the recording time from 16 working hours to less than one hour of recording. Here, the virtual data has the same accuracy as the conventional data. We validate the efficacy of parsimonious seismic interferometry with the time-lapse mentoring idea with field examples, where we were able to record 30 different data sets within a 2-hour period. The recorded data are then processed to generate 30 snapshots that shows the spread of water from the ground surface down to a few meters.
