Marine Seismic Survey Services with NCS SubSea

As leaders in marine geophysical service sector, NCS SubSea and P-Cable 3D Seismic offer a comprehensive solution for ultrahigh resolution (UHR) marine seismic surveying featuring our patented P-Cable technology. Working with trusted industry partners and our sister companies in the OYO Group (a leading geoscience enterprise based in Japan), we provide a full scope solution from initial survey design through to final data processing and interpretation.

These comprehensive seismic survey services can be employed for a wide range of industries and applications:

  • Geohazard and site surveys
  • Oil and gas exploration, appraisal, field development, and reservoir management
  • Offshore wind farm and construction projects
  • Near shore infrastructure risk assessments, including nuclear power generation facilities
  • Carbon sequestration studies to confirm seal integrity
  • Detailed marine geological studies to understand complex structural compartmentalization and higher order stratigraphic features
  • Methane hydrate investigations

Seismic Survey
Design & Planning

P-Cable 3D Seismic invented and developed the patented P-Cable 3D Seismic system. We have more than a decade of experience in planning, rigging, and surveying using the P-Cable system. During tailored seismic surveys for clients as well as multi-client surveys in cooperation with TGS, we have collected over 3,600 square kilometers of commercial ultrahigh resolution 3D data and 7,000 kilometers of commercial 2D wide-azimuth tie-lines. We have successfully operated the P-Cable system in a variety of areas around the globe, including the Barents Sea – one of the harshest environments in the world for marine seismic operations.

Near Offset Coverage

P-Cable performs a detailed analysis of infrastructure within and around the survey area to ensure the crew accounts for all known obstacles. We have extensive experience designing and executing seismic surveys in congested, high-traffic oilfields

P-CABLE ACQUISITION CALCULATOR

P-Cable Acquisition Calculator

Our custom built P-Cable acquisition calculator tool will let you assess the impact of survey geometry variations by adjusting basic survey parameters to determine the optimum tradeoff between spatial sampling, survey efficiency, and fold of coverage.

P-Cable Ultrahigh Resolution Seismic Data Acquisition

NCS SubSea (NCS) and P-Cable 3D Seismic have pioneered the commercial development of the P-Cable ultrahigh seismic resolution recording system as an unrivaled tool for providing extremely detailed images of geology at and beneath the seafloor. Using proprietary navigation and seismic acquisition technologies to augment the accuracy, robustness, and reliability of this system over the past several years, we have been able to produce subsurface images of astounding quality and fidelity.

Seismic survey data acquisition is performed using conventional, low-capacity 3D seismic vessels or other vessels of opportunity (such as platform supply vessels) in situations where conventional seismic vessels are not available. The ultimate in versatility, our compact, modular acquisition system can be air-freighted to the mobilization port for installation onboard the selected vessel. The small footprint of the P-Cable system is easily deployable from the back of most vessels.

Shallow tow depths and careful design of both source and receiver arrays, coupled with extremely fine sampling intervals both temporally and spatially, result in broadband images with exceptional levels of detail and clarity compared to conventional marine seismic acquisition methodologies. Simply put, our system can provide the clarity and resolution to equip your project with the best information available.

Real-Time Quality Control & Fast Track Data Delivery

Quality control of marine seismic data is key to acquiring good data. With our partner RadExPro, we offer superior real-time quality control with RadExPro software, tailored to P-Cable systems. We also provide optional onboard fast-track processing of 2D and 3D data, for quick data delivery for onshore interpretation. This ability is extremely important for decision-making processes during ongoing surveys and surveys with tight deadlines due to follow-on activities.

Real-time quality control is an essential component of every project that P-Cable undertakes.

Marine Seismic Data Processing & Interpretation

Working with our industry partners we have more than a decade of experience with processing and interpretation of ultrahigh resolution (UHR) 3D marine seismic survey data. Together with RadExPro, TGS, DUG, and other industry partners we have developed state-of-the-art, broadband 3D marine seismic processing workflows for P-Cable data. Our collaboration with RadExPro began in 2005, and together, we have developed navigation and QC processing software and workflows uniquely suited to the P-Cable technology.
