摘要： Systems and methods of performing a seismic survey are provided. The system includes a seismic data acquisition unit having a transmitter window disposed in a first aperture of a lid, and having a receiver window disposed in a second aperture of the lid. A first gasket is positioned between the transmitter window and the first aperture to provide a clearance greater than a threshold to allow the transmitter window to deform. A second gasket is positioned between the receiver window and the second aperture to provide a clearance greater than the threshold to allow the receiver window to deform. At least one of the transmitter window and the receiver window of the seismic data acquisition unit are configured to pass at least one of optical and electromagnetic communications to or from an extraction vehicle via at least one of a transmitter window and a receiver window of the extraction vehicle.

摘要： Systems and methods of optical link communication with seismic data acquisition units are provided. The systems and methods can perform at least portions of seismic data acquisition survey. A plurality of seismic data acquisition units can be deployed on a seabed. An optical communications link can be established between an extraction vehicle and at least one of the seismic data acquisition units. A frequency of the at least one seismic data acquisition unit can be syntonized or synchronized via the optical communications link. The at least one seismic data acquisition unit can be instructed to enter a low power state subsequent to syntonizing the frequency of the at least one seismic data acquisition unit. The seismic data acquisition unit can exit the low power state and acquire seismic data in an operational state.

摘要： The present disclosure is directed to a helical conveyor for underwater seismic exploration. The system can include a case having a cylindrical portion. A cap is positioned adjacent to a first end of the case. A conveyor having a helix structure is provided within the case. The conveyor can receive an ocean bottom seismometer (“OBS”) unit at a first end of the conveyer and transport the OBS unit via the helix structure to a second end of the conveyor to provide the OBS unit on the seabed to acquire the seismic data. The system can include a propulsion system to receive an instruction and, responsive to the instruction, facilitate movement of the case.

摘要： Systems and methods for deployment and retrieval of ocean bottom seismic receivers. In some embodiments, the system includes a carrier containing receivers. The carrier can include a frame having a mounted structure (e.g., a movable carousel, movable conveyor, fixed parallel rails, or a barrel) for seating and releasing the receivers (e.g., axially stacked). The structure can facilitate delivering receivers to a discharge port on the frame. The system can include a discharge mechanism for removing receivers from the carrier. In some embodiments, the method includes loading a carrier with receivers, transporting the carrier from a surface vessel to a position adjacent the seabed, and using an ROV to remove receivers from the carrier and place the receivers on the seabed. In some embodiments, an ROV adjacent the seabed engages a deployment line that guides receivers from the vessel down to the ROV for “on-time” delivery and placement on the seabed.

摘要： A self-contained, wireless seismic data acquisition unit having a cylindrically shaped case with smooth side walls along the length of the case. A retaining ring around the circumference is used to secure the cylindrical upper portion of the case to the cylindrical lower portion of the case. Interleaved fingers on the upper portion of the case and the lower portion of the case prevent the upper portion and the lower portion from rotating relative to one another. Ruggedized external electrical contacts are physically decoupled from rigid attachment to the internal electrical components of the unit utilizing electrical pins that “float” relative to the external case and the internal circuit board on which the pins are carried. The seismic sensors in the unit, such as geophones, and the antennae for the unit are located along the major axis of the cylindrically shaped case to improve fidelity and timing functions.

摘要： The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station. Any one seismic unit in the array is capable of transmitting radio signals to several other seismic units positioned within radio range of the transmitting unit, thus allowing the system to select an optimal transmission path. Utilizing an array of seismic units permits transmission routes back to a control station to be varied as needed. In transmissions from the most remote seismic unit to the control station, each unit within a string receives seismic data from other units and transmits the received seismic data along with the receiving unit's locally stored seismic data. Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array.
