Abstract:
Apparatus and methods for acquiring seismic data using a seabed seismic data cable positioned on a seabed are described, including correcting for the effect of one or more sensor non-linear motions, which improves accuracy of seismic data. One or multiple non-linear movements of the sensor may be corrected for. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
Abstract:
A system includes an unmanned marine vessel having a hull; a multi-dimensional seismic sensor array coupled with the hull, wherein the multi-dimensional seismic sensor array is configured to acquire seismic survey data in multiple directions; wherein the unmanned marine vessel comprises a power source configured to drive and provide propulsion to the unmanned marine vessel; and an umbilical cord for coupling the multi-dimensional seismic sensor array with the hull of the unmanned marine vessel, wherein the umbilical provides electrical communication between the unmanned marine vessel and the multi-dimensional seismic sensor array.
Abstract:
An unmanned water vessel can include a body defining an internal volume and having a shape adapted to travel through water, with a front and a back; at least one directional device that is exposed to the flow of water past the vehicle when the vehicle travels in a forward direction, the directional device having a first position that provides an angle of attack through the water flow and a second position that provides a second angle of attach through the water flow; and a control system that provides commands to the at least one directional device in view of a starting point, an end point, and at least information about water flow expected to be encountered by the water vessel during travel.

Abstract:
Systems and methods for carrying out seismic surveys and/or conducting permanent reservoir monitoring with autonomous or remote-controlled water vehicles, including surface and submersible vehicles, are described. Additional methods carried out by autonomous or remote-controlled water vehicles and associated with seismic surveys are further described.
