摘要： System and method for monitoring a reservoir underwater. The system includes plural nodes, each having a seismic sensor for detecting seismic waves; a remote operated vehicle (ROV) configured to deploy or retrieve the plural nodes to seabed; and an autonomous underwater vehicle (AUV) configured to monitor and exchange data with the plural nodes. At least one node of the plural nodes has a head that houses the seismic sensor and the head is configured to burrow in the seabed, up to a predetermined depth, and the head remains in electrical contact through a connector with a base of the at least one node.

摘要： Methods and systems for separating surface wave velocity information from surface wave noise in seismic data are described. The seismic data can be comprised of irregularities in spatial sampling, non-stationarity in time and non-stationarity in frequency. The methods and systems can then be adapted to create a multi-component dip filter that removes high amplitude dispersive noise from the seismic data based on the use of slant stacking.

摘要： Various methods (300, 500, 1100) 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 (400, 600, 700) 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.

摘要： Methods and systems for separating multiple events from primary events in noisy seismic data are described. Multiples are predicted and then the predictions are improved by least-square matching filtering in the space and time domain. An adaptive curvelet domain separation (ACDS) is then performed and the ACDS equation is solved with an iterative soft-thresholding technique. Further processing can be added to compensate for prediction inaccuracy or variable/excessive seismic data noise by dividing the seismic data into predetermined bands and processing each band independently.
