Abstract: A floating vessel based system generates a multidimensional seismic data set for a target area. The floating vessel based system includes a seismic source proximate to a floating vessel, providing a plurality of seismic energy pulses through water to the target area forming a plurality of reflected seismic energy pulses, a non-stationary seismic node configured for being towed from the floating vessel using at least one rope through the water, a non-stationary seismic node, and a second processor with second data storage on the floating vessel. The second data storage instructs the second processor to receive, each digital data series, combines the digital data series for all non-stationary seismic nodes utilized, and automatically generates multidimensional seismic data set for the target area.

Abstract: Method and apparatus for marine seismic data collection and high resolution imaging is described. A marine seismic surveying flotilla is described for acquiring seismic data from both beneath an obstruction and in unobstructed water using a configuration of floating energy source vessels and a floating acquisition vessel towing an array of parallel seismic streamers. Different energy sources can be disposed on or towed by floating vessels that are not the floating acquisition vessel, with these energy sources maintained at a preset radius from a center of the array of parallel seismic streamers.

Abstract: Computer instructions for determining coordinates for nodes on a wire secured to tow lines of a floating vessel for analyzing geological formations is provided. The computer instructions can use sensors in communication with a processor to determine the coordinates of nodes and provide azimuths tangential to the wire. A library of nominal values for polynomial coefficients, a library of known distances along the wire, and a library of preset limits can be stored in a data storage. The computer instructions can: receive sensor information, compute bearing, reorient the coordinates, rotate the azimuth, construct a polynomial algorithm, compute the azimuth, form a residual, compute updated differences until the residual is within preset limits, calculate local coordinates for nodes, and rotate the local coordinates from the local coordinate system to the projected coordinate system.

Abstract: A method for positioning a wire having nodes and streamers is provided herein. The wire can be secured to tow lines secured to a floating vessel for detecting near surface geology formations. The method can use in-water sensors deployed proximate to the wire near the tow lines, and a processor with data storage in communication with the in-water sensors. The method can use a data array, a library of data formats, a library of wires, a library of preset limits, and a network. The method can include receiving sensor information, filtering sensor information, verifying filtered signals, constructing and modifying a mathematical model, obtaining a list of coordinates, constructing a real-time display of the wire, identifying a location of at least one streamer, transmitting alarms, creating a trend analysis over time and event-by-event, and creating a log file using the industry standard data formats.

The system can include sensors in communication with a processor to determine the coordinates of nodes and provide azimuths tangential to the wire. A library of nominal values for third, fourth, or fifth order polynomial coefficients, a library of known distances along the wire, and a library of preset limits can be stored in a data storage. The system can include computer instructions to receive sensor information, compute bearing, reorient the coordinates, rotate the azimuth, construct a third, fourth, or fifth order polynomial algorithm, compute the azimuth, form a residual, compute updated differences until the residual is within preset limits, calculate local coordinates for nodes, and rotate the local coordinates from the local coordinate system to the projected coordinate system.
