  • a seismic survey can do this and can be performed by actuating a source that provides a signal that travels into an earth formation, and reverberates or reflects off of various portions of the formation.
  • the reflections or reverberations can be detected by seismic sensors, and transformed into data that is analyzed so that it shows attributes of the subsurface formation, such as the existence, location and shape of a hydrocarbon or other mineral deposit.
  • the surveyed formations can be on dry land, or underneath bodies of water such as oceans or lakes. They can also be in a shallow water area near the shore of a body of water or in a swamp / wetland area called a transition zone.
  • a marine seismic source WG Docket No. IS14.8312 can be actuated to provide a source signal that travels through the water and into the formation, where the signal reflects and travels upward through the water where it is detected by the sensors and turned into seismic data.

  • the sections can be connected together to make streamer lengths of up to 12 km. Cables of this length can use electrical power to transmit data along the length of the cables and to eventually record the same. Towed marine streamer spreads may have between 6 and 14 streamers and are seldom shorter in length than 3 km.
  • the streamers can be towed by a vessel and given the length and weight of the streamers, a significant amount of tension (and resulting strain) can be placed on the streamers. Also, by way of handling activities (deployment and retrieval), and inadvertent occurrences such as tangles, or hard contact with sharp or hard objects on the vessel, the streamers can experience forces such as excessive bending stress/strain, scraping, impact, and puncturing.

  • Marine seismic surveys are very capital intensive in that the vessels tend to be very expensive. For manned vessels, the crew is expensive. The marine seismic cables are expensive. From a business perspective any downtime because of technical failures such as streamer failures from the failure modes noted above can be very costly, and compromise profitability for a job quite quickly. It is therefore valuable to reduce technical downtime.
