  • METHOD AND APPARATUS FOR DETERMINING THE NATURE OF SUBMARINE RESERVOIRS
    Publication number: 20100045295
    Abstract: A method of producing a survey report on the presence and nature of a subterranean strata: includes simultaneously towing an EM field transmitter and a seismic source behind a vessel, towing at least one streamer behind the vessel, said streamer or streamers having EM field receivers for measuring an electric field and seismic receivers for measuring a seismic response, applying an EM field to the strata using the EM field transmitter and detecting an EM field response using the EM field receivers, applying a seismic event to the strata using the seismic source and detecting the seismic response using the seismic receivers, analysing the EM field response, analysing the seismic responses and reconciling the EM field response and the seismic response to produce the survey report.

  • Method for seismic migration using explicit depth extrapolation operators with dynamically variable operator length
    Patent number: 7039525
    Abstract: Explicit depth extrapolation operators are constructed with variable operator lengths depending on maximum dip angle, accuracy condition, and wavenumber. Operator tables are then constructed using the explicit depth extrapolation operators. In a further embodiment, depth migration is performed using the explicit depth extrapolation operators from the operator tables.
