Abstract
The first depth velocity model over the field was created in 2011, using data acquired in 2008 as part of a high definition (HD) survey collected on a 6.25 x 12.5 binning grid with relatively shallow streamer and gun depths (5 m and 6 m respectively) aimed at maximizing the signal bandwidth and spatial resolution of the faulted sandstone reservoir. Here we present further work updating the 2011 model by combining the 2008 HD survey with an earlier 1997 regional survey to achieve a dual azimuth reprocessing.
该油田的第一个深度速度模型是在2011年创建的,使用的数据是2008年在6.25 x 12.5 bin网格上收集的高清(HD)调查数据的一部分,该网格的拖缆和枪的深度相对较浅(分别为5米和6米),旨在最大限度地提高断层砂岩储层的信号带宽和空间分辨率。在这里,我们提出了进一步的工作,通过结合2008年HD测量和1997年早期的区域测量来更新2011年模型,以实现双方位角再处理。
