Key Features and Advantages

Unrivaled Temporal and Spatial Resolution

With P-Cable, shallow tow depths and careful design of both source and receiver arrays, coupled with extremely fine sampling intervals both temporally (1/4 to 1/2 milliseconds) and spatially (1.5625 to 6.25 meter bins), result in broadband images with exceptional levels of detail and clarity compared to conventional marine seismic acquisition methodologies.

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.

Extremely Dense Near Offset with P-Cable

Focusing exclusively on near offset coverage allows us to distribute our seismic coverage effort more densely in the inline and crossline domains rather than the offset domain, resulting in images of complex subsurface geology such as channels, faults, thin layers, prograding deltas, and higher-order stratigraphic sequences that are not resolved by conventional acquisition technologies.

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.

Compact and Configurable P-Cable

The relatively small amount of equipment and streamers, along with the use of fewer winches/reels than conventional seismic, means that it is feasible to air freight equipment to the job site and install it on a vessel of opportunity. Our ability to design the streamer spacing and receiver group interval to meet specific geophysical and geologic objectives means that we can field a source and receiver spread that is tailored to your specific application.
