Seismic data collection system with sparse nodes and mini-streamers
A recently granted patent (Publication Number: US11966000B2) discloses a correlated sparse nodes and mini-streamers system designed for collecting seismic data from the surveyed subsurface. The system consists of plural nodes distributed on the ocean bottom with a specific inline distance between them, along with a mini-streamer spread comprising multiple mini-streamers with sensors to acquire traces. The nodes and mini-streamers work in tandem to simultaneously gather seismic data, enhancing data collection efficiency.
The system's configuration involves distributing nodes in a grid pattern along inline and crossline directions, while the mini-streamers are towed parallel to the inline direction by a vessel. Additionally, the mini-streamers have a limited length, and the spacing between nodes is specified to optimize data collection. The patent also includes a method for processing the acquired seismic data, involving combining sparse node seismic data with mini-streamer spread data to generate a detailed image of the subsurface. The method allows for the integration of previously acquired data, such as ocean bottom or traditional streamer data, and includes processing techniques like full waveform inversion for comprehensive analysis. This innovative system and method offer a sophisticated approach to seismic data collection and processing, potentially improving the accuracy and efficiency of subsurface imaging in various applications.
