Key Features and Advantages
Comparison of conventional 3D streamer data (left) with P-Cable UHR3D data (right) in the Barents Sea, offshore Norway. Both datasets have been processed to maximize the bandwidth available within the recorded data, including broadband deghosting. The conventional dataset is 80 fold in 6.25 x 25 meter bins with 6000-meter offsets and the P-Cable UHR dataset is 4 fold in 3.125 x 3.125 meter bins with 100-meter offsets. The time slices in the bottom figures are at a two-way travel time of approximately 665 milliseconds.

The histogram at the left of this figure illustrates the short and homogeneous offset distribution of the P-Cable UHR system compared to conventional streamer systems. This dense near offset coverage is one of the key factors that allow the UHR system to produce ultrahigh resolution images of features such as moraines, mass transport deposits and plough marks.
