P-Cable is towed from a smaller vessel. When combined with the very short streamers, high maneuverability makes P-Cable an optimal solution for congested survey areas. Also, the shallow source and receiver tow depths used in P-Cable surveys (2 – 4 m) make it attractive for shallow water surveying.
Towed P-Cable streamer spreads use 8 to 24 short streamers towed at 6.25 –12.5 m separation. Each streamer is 50-100 m in length and uses receiver intervals of 3.125 – 6.25 m. Recording sample rates are as small as 0.25 ms. Source frequencies beyond 1000 Hz enable UHR imaging of the near-surface.
Detailed UHR3D data is ideal for smaller areas and complex targets, such as highly fractured, thin, or compartmentalized formations. For the highest spatial resolution, P-cable data will typically focus on the 50 – 150 m offset range, while for offshore wind farms the offsets are more typically 10 – 100 m.
