摘要： A method is provided for analysing data from an electromagnetic survey of a region so as to indicate the presence of a hydrocarbon reservoir. The survey provides vertical magnetic dipole data and electric dipole data, or provides measurement data from which these dipole data may be determined. The amplitude of the vertical magnetic dipole data is determined, optionally after normalising the data with reference date relating to the same region. Similarly, the amplitude of the electric dipole data is determined, optionally after similarly being normalised. The amplitudes are then compared to provide an indication of the likelihood of the presence of hydrocarbons in the region.

摘要： A method of determining a vertical component (formula I) of particle velocity from seismic data acquired at a receiver disposed within a water column, comprises determining the vertical component of particle velocity from the pressure acquired at the receiver using a operator accurate for seismic data acquired at a depth beneath the surface of the water column of up to at least 0.4 times the minimum wavelength of seismic energy used to acquire the seismic data. The vertical component of particle velocity from the pressure acquired at the receiver may be determined using the equation (2). This equation is exact, and may be applied to seismic data acquired at any depth below the surface of the water column. Alternatively the equation may be truncated to reduce the processing required, although this may place a limit on the maximum depth of acquisition of data with which the truncated equation can be used.

摘要： A method is provided for processing electromagnetic data, such as data obtained by mCSEM techniques, representing a region of the Earth covered by water such as seawater. A source (1) such as a horizontal electric dipole, is used with one or more receivers (5) to obtain the data. The data are then processed to remove an airwave contribution having a first component, which propagates without reflection from the source to the receiver, and second components whose propagation paths undergo reflections at the air/water interface (3) and at the water/sediments interface (4). The propagation paths of the second components have vertical portions at the source (1) and at the receiver (5) resulting from reverberations between the interfaces (3, 4).

摘要： A method of determining a vertical component of particle velocity from seismic data acquired using at least one receiver disposed within a water column comprises determining the vertical component of particle velocity from the pressure at a first location and a second location. The first location is the location of a first receiver, and is vertically beneath the second location. The method uses an operator accurate for seismic data acquired at a vertical separation between the first and second locations of up to at least 0.4 times the minimum wavelength of seismic energy used to acquire the seismic data. The second location may be at or above the surface of the water column. Alternatively, the method be applied to a twin streamer seismic surveying arrangement in which the second location is below the surface of the water column and is the location of a second receiver.

摘要： A method of deriving a calibration filter for electromagnetic data is provided. The method comprises providing a source (21, 22) of electromagnetic radiation and subsequently measuring components of the source electromagnetic field (23, 24, 25) at a receiver when the source is sufficiently close to the receiver that the down-going signal dominates over the up-going signal reflected from features below the receiver. Such a measurement can be used in frequency domain analysis (26, 28, 29) to extract the down-going signal component and derive a calibration filter for the receiver. The method is repeated (27, 30) for each receiver used in an electromagnetic sounding survey.
