Abstract: One or more portions of a streamer or other equipment of a seismic survey system (e.g., birds, buoys, deflectors, etc.) are covered with protective removable skin sections. A protective removable skin section includes a flexible sheet and a reversible closure system configured to join edges of the flexible sheet. The protective removable skin section may be mounted onboard of a vessel, when the equipment is deployed.

Abstract: Various methods preserve or restore the low roughness throughout an outer shell of a device (e.g., a streamer) used underwater for seismic surveys, by applying various substances that fill micro-cracks, are easy to polish or are self-healing. Apparatuses used to implement these methods may be used shortly before the devices are deployed in water, for example, having the device passing through such an apparatus as it is moved to be deployed in water.

Abstract: Presented are methods and systems for collecting marine seismic data. The collected seismic data can be low frequency (e.g., less than 10 Hz) or it can be a full seismic bandwidth (1-200 Hz) depending on if the low frequency tuned sources and tuned receivers are combined with conventional sources and receivers. The low frequency sources can be towed or they can be autonomous and positioned in the survey area by tether, drifting or self-propelled. The tuned low frequency receivers are towed at a depth greater than conventional receivers and the sources can be fired independently or simultaneously.

Abstract translation: 提出收集海洋地震资料的方法和系统。 收集的地震数据可以是低频（例如，小于10Hz），或者可以是完全地震带宽（1-200Hz），这取决于低频调谐源和调谐接收机是否与常规源和接收机组合。 低频源可以被牵引，或者可以通过系绳，漂移或自推进自主地定位在测量区域。 调谐的低频接收机在比常规接收机更大的深度被牵引，并且可以独立地或同时地发射源。

Abstract: A marine source element is configured to generate seismic waves. The source element includes a body and a source actuator attached to the body and configured to generate the seismic waves. The body is autonomous from a vessel towing streamers along a pre-plot line associated with a seismic survey.

Abstract: A marine streamer spread for acquiring seismic data, the spread including a streamer having a first portion and a second portion; the first portion including both first pressure sensors and pressure derivative sensors for acquiring the seismic data; and the second portion including second pressure sensors. The first portion imparts ghost diversity to the seismic data by having a variable-depth profile and the pressure derivative sensors impart polarity diversity to the seismic data.
