Seismic Reflection Method. 3

On a recorded trace, (E1, R12) for example, the time (of arrival) of different reflections is not representative of the depth of the corresponding reflectors (or more exactly the distance travelled to these reflections). The lengths of the oblique travel paths (in solid lines below) are a function of not only depth but also a function of the distance E-R. A diagram illustrates the seismic reflection correction process. It shows a horizontal line labelled E, m, and R, representing different points. Arrows indicate paths of seismic waves reflecting off layers labelled M 1, M 2, M 3, and their corrected positions M 1 prime, M 2 prime, M 3 prime. The lower part of the diagram compares corrected and raw traces. Arrows indicate the time shift t applied to correct the trace. https://www.w3.org/1999/xlink" xlink:href=" https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003761020/e10523ab-dbe3-4c4f-8f3e-863ae3683950/content/pg379_1.tif "/>
