Abstract: The present disclosure provides a method for modeling and analyzing the impact of different seismic surveying and imaging techniques on a subterranean formation by creating a black hole boundary condition around a particular region in the formation where at least one of the physical characteristics is unclear and may distort the seismic modeling results. The black hole boundary conditions will eliminate any energy wave that enters, exit or reflect off the region so as to avoid any image distortion caused by this region. The resulted image data is compared with the image data obtained without using the black hole boundary conditions to determine the impact of this region, and proper correction can be made to more precisely and accurately model the formation

Abstract: Improved methods of gather high fidelity vibratory seismic surveys for ZenSeis® systems wherein at least one optimal phase encoding schemes for surveys having 2-8 vibratory sources are disclosed. These encoding schemes can be hard coded into the source controller and will allow for quality data to be obtained on each survey. Further, the data will also have the best separation during inversion processing steps, leading to an optimal seismic survey.

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.
