Abstract: Vibrators for producing seismic signals for use in oil and gas exploration are equipped with segmented base plates, each segment being independently controlled and activated. The use of an array of base plate segments allows the individual segments of the array to be activated in a particular pattern, thus generating S-waves and other unconventional wave patterns for seismic use.

Abstract: A method of performing notch compensation and a system to perform notch compensation for a first seismic streamer are described. The method includes disposing the first seismic streamer at a first depth, where the seismic streamer includes a first set of sensors to receive reflections resulting from a seismic source, the reflections indicating a notch at a frequency. The method also includes disposing a second seismic streamer at a second depth, the second depth being less than the first depth and the second seismic streamer including a second set of sensors to receive reflections resulting from the seismic source. The method further includes processing the reflections received by the first set of sensors and the second set of sensors together to derive the match filter, and applying the match filter to the reflections received by the first set of sensors of the first seismic streamer to compensate for the notch.

Abstract: A method of generating a magnetic anomaly map and a system to develop a magnetic anomaly map are described. The method includes obtaining magnetic compass data recorded by two or more magnetic compasses disposed along a seismic streamer that traverses a first area and obtaining measurements from one or more navigation systems over the first area. The method also includes determining a correct position of each of the two or more magnetic compasses based on the measurements from the one or more navigation systems, and comparing the magnetic compass data with theoretical magnetic field data at the correct positions to generate a magnetic anomaly map.

Abstract: The illumination/imaging of a theorized target horizon that is below a theorized velocity contrast horizon where the velocity contrast horizon may represent the bottom of a salt dome by assessing the path of seismic energy for critical angle reflection/refraction and tabulates the successful paths and unsuccessful paths. For some subsurface locations, seismic energy will not reach the surface above the velocity contrast due to the shapes of the velocity contrast horizon and target horizon and the velocity model through which the studied waves propagate. Displays may be prepared and used for understanding illumination/imaging of the geology for drilling, reacquisition, and reprocessing to elicit information about subsurface geology that may have been overlooked or ignored. Future surveys avoid expensive surveying which cannot obtain useful seismic data as determined by the velocity contrast for the target locations due to the shapes of the horizons and the velocity model.
