摘要： An acoustic navigation system includes a vessel and an interrogation unit towed behind the vessel below the surface of the water, a tail acoustic transponder trailing behind the interrogation unit, and a pair of surface acoustic transponders towed behind the vessel on the surface of the body of water. The interrogation unit generates an acoustic interrogation signal and receives responses from each of the tail acoustic transponder and the surface acoustic transponders from which it triangulates its position. The surface acoustic transponders may further include GPS receivers for receiving positioning information from GPS satellites. Additional acoustic transponders on instruments located on the floor of the body of water respond to the interrogation signal to allow triangulation of the location of the instruments.

摘要： A sensor for electric field measurement at the floor of a body of water has at least one pair of square or rectangular electrodes (139, 140) with a known area positioned in parallel separated by a distance and connected by a resistor (120) having a value that matches the resistance of the water between the electrodes. The detected electric fields may be naturally-occurring or artificially generated using a controlled electromagnetic (EM) source. In a preferred embodiment, three pairs of square or rectangular parallel electrodes (139-144) are arranged to form the six sides of a rectangular prism or cube, thus providing for electric field measurement along three axes to provide horizontal and vertical measurements of a hydrocarbon reservoir or other feature of interest under the floor of the body of water.

摘要： The magnetotelluric system for seafloor petroleum exploration comprises a first waterproof pressure case containing a processor, AC-coupled magnetic field post-amplifiers and electric field amplifiers (the "logger unit"), a second waterproof pressure case containing an acoustic navigation/release system, four silver-silver chloride (Ag-AgCl) electrodes mounted on booms and at least two magnetic induction coil sensors. These elements are mounted together on a plastic and aluminum frame along with flotation devices and an anchor for deployment to the seafloor. The acoustic navigation/release system serves to locate the system by responding to acoustic pings generated by a ship-board unit and receives a release command which initiates detachment from the anchor so that the buoyant package floats to the surface for recovery. The electrodes used to detect the electric field are configured as grounded dipole antennas. Booms by which the electrodes are mounted onto frame are positioned in an "X" configuration to create two orthogonal dipoles, which are used to measure the complete vector electric field. The magnetic field sensors are multi-turn Mu-metal core coils which detect within the frequency range typically used for land-based MT surveys. The magnetic field coils are encased in waterproof pressure cases and are connected to the logger package by high pressure waterproof cables. The logger unit includes the amplifiers for amplifying the signals received from the various sensors, which signals are then provided to the processor which controls timing, logging, storing and power switching operations. Temporary and mass storage is provided within and/or peripheral to the processor.

摘要： The system and method provided modify a conventional seafloor long-wire electromagnetic (LEM) receiver by increasing the number of discrete antennae placed on the long wire. Two dipoles of electric field data are positioned exactly adjacent to each other, providing input to the same data logger system located within a seafloor survey unit to which the long wire is connected. Highly precise electric field gradients can be obtained by taking the difference of the measurements of the two electrodes, both for amplitude and phase. Any common-mode source of noise, such as magnetotelluric signals and receiver instrument noise will be rejected when the signals from the two electrodes are differenced. An acoustic navigation system utilizes a plurality of transponders to permit triangulation for accurate source-receiver ranging.

摘要： A system for mapping electrical conductivity of the seafloor incorporates a plurality of data logging units, where each unit (100) is an assembly adapted for deployment at a location on the seafloor for measurement of horizontal electric and magnetic fields. Rigidly attached and extending vertically from the unit assembly is a vertically-oriented substantially rigid arm (158) having a pair of vertically-displaced electrodes (160, 162) disposed on the arm to create a vertically-oriented dipole antenna. The electrodes are in electrical communication with an amplifier located within the assembly which generates an amplified signal which is then provided to a data logging processor also located within the assembly. The processor collects time series of amplified electric field and magnetic signals over a predetermined period of time.

摘要： The system and method for real-time monitoring of a hydrocarbon reservoir (4) during extraction include an electro-magnetic source assembly (16) for transmitting a first plurality of electromagnetic fields. A plurality of seafloor antennae (30a–30d) is distributed over an area of the seafloor (8) corresponding to the reservoir (4), where each antenna (30a–30d) comprises recieves electrode array (30a–30d) adapted for receiving a second plurality of electromagnetic fields and generating signals corresponding to the detected fields. A data logging processor receives the signals over time and stores data corresponding to the signals. Different combinations of the receiver electrode are used in combination with transmitter antennae for measuring vertical, radial and/or azimuthal fields. Transmission and detection of the fields can be performed continuously or at timed intervals during hydrocarbon extraction to estimate the rate and efficiency of extraction.
