Figure 1 – A 2D (Two-Dimensional) seismic section showing the two coordinate axes of horizontal distance (labeled CMP) at the top of the figure and vertical time (labeled TWT) along the sides of the figure.

Figure 2 – Examples of ultrasound images of a developing fetus. This type of imaging using sound waves is completely analogous to the seismic technology we use to image the earth’s subsurface. The three images above show a 2D (planar) ultrasound image on the left, a 3D (volumetric) ultrasound image in the center, and High Definition (HD) 3D volumetric ultrasound image on the right. The HD ultrasound image is analogous to the UHR3D (Ultrahigh Resolution3D) image that P-Cable produces of the earth’s subsurface.

Figure 3 – Comparison of a photograph of a road cut in a mountainous region with faulted geology (left) with the 2D seismic section shown in the previous Figure 1 (right), which also exhibits faulted geology.
Figure 4 – Perspective view of images from 3D seismic data volumes that provide a volumetric image of the earth’s subsurface. The vertical sides of these images are referred to as vertical seismic sections and the horizontal surface of these images are referred to as time slices (or depth slices if the seismic data have been imaged in depth).
Figure 5 – The Grand Canyon, a massive erosional feature in Arizona that exposes both the beauty and the complexity of geologic features beneath the surface of the earth that are normally hidden from our view. The seismic imaging method uses low-frequency sound waves to produce images of the subsurface geologic structures without the need for erosional exposure.
