背景
Sercel 针对海洋震源技术的基准进行了生产质量控制，涉及传统脉冲震源和 Gi-Source，以测量其声学性能并展示其地球物理优势。调查是在非常浅的水域进行的。在这种情况下，基准由地震操作员提供；但是，Sercel 可以在需要时提供船上现场服务工程师 (FSE)。

方法
我们的 Sercel 专家远程验证了质量控制参数。下图显示了预测和记录之间的微小时间偏差。这种偏差可能归因于几何形状、深度或压力的变化，但最有可能是因为 5 米深度的注入延迟不同。用户手册建议注入延迟为 44 毫秒。然而，似乎在现场，这个参数被设置为大约 37 毫秒。

结论
由此，我们可以得出结论，Gi-Source 功能使用得当，但可以改进。此外，结果还包括基于源输出的精确建模对近场水听器 (NFH) 灵敏度校准的评估。我们还改进了校准过程以提高灵敏度准确性，这有助于对源技术进行基准测试。

Sercel conducted a production QC for a benchmark on marine source technology, involving both conventional impulsive sources and the Gi-Source, to measure their acoustic performance and demonstrate their geophysical benefits.

BACKGROUND
Sercel conducted a production QC for a benchmark on marine source technology, involving both conventional impulsive sources and the Gi-Source, to measure their acoustic performance and demonstrate their geophysical benefits. The survey was conducted in a very shallow water area. In this case, the benchmark was provided by the seismic operator; however, Sercel can supply onboard Field Service Engineers (FSE) when required.

METHODOLOGY
The QC parameters were validated remotely by our Sercel experts. The graph below shows a small deviation in time between the prediction and the record. This deviation could be attributed to variations in geometry, depth, or pressure, but it is most likely due to a different injection delay for a depth of 5 meters. The user manual recommends an injection delay of 44 ms. However, it seems that in the field, this parameter was set to approximately 37 ms.

CONCLUSIONS
From this, we can conclude that the Gi-Source feature was used properly but could be improved. Additionally, the results included an evaluation of the sensitivity calibration of the Near-Field Hydrophones (NFH) based on accurate modeling of the source output. We also improved the calibration process to enhance sensitivity accuracy, which facilitated the benchmarking of the source technology.
