Abstract
The present disclosure generally relates to systems and methods for acquiring seismic data. In one exemplary embodiment, a method for acquiring seismic data is described in which recorder instruments are deployed to the seafloor and utilized for recording pressure wave and shear wave data. An acoustic array, displaced from the seafloor, is also provided for sending acoustic signals to the instruments on the seafloor. The orientation of the instruments on the seafloor is determined via acoustic communication between the acoustic array and the instruments. Related systems and methods for acquiring seismic data are also described.
Claims26
A method for acquiring seismic data, comprising:
- deploying a plurality of instruments, each instrument having sensors for acquiring seismic data and being adapted for contact with the seafloor, and each instrument further having at least two transponders;
- providing an acoustic array spaced apart from the plurality of instruments when the instruments are in contact with the seafloor;
- determining a geographical orientation of at least one of the instruments on the seafloor, whereby the orientation is determined by sending acoustic signals from the acoustic array to at least one of the transponders and receiving acoustic signals from the two transponders;
- and
- acquiring seismic data via the sensors.
A system for acquiring seismic data, comprising:
- a plurality of deployable instruments having sensors for acquiring seismic data, each of the instruments comprising an instrument housing disposed on a lifting frame, the instrument housing being generally elongated and including a pair of tubular portions and a central portion in communication with one another, whereby a first transponder is disposed at a first end of the instrument housing and a second transponder is disposed at a second end of the instrument housing, the instrument housing further having an acoustics controller disposed therein;
- an acoustic array spaced apart from the instruments when the instruments are deployed, the acoustic array being operable for determining an orientation of at least one of the plurality of instruments relative to a geographic reference, whereby the acoustics controller facilitates acoustic communication between the instrument and the acoustic array;
- and
- a data conditioning system for retrieving the seismic data from the instruments and conditioning the seismic data from the at least one of the plurality of instruments according to the orientation of the at least one of the plurality of instruments.
