Abstract: The present invention relates to a method for synchronizing continuous seismic survey. In particular, the present invention employs a semaphore scheme for the vibes to autonomously and continuously initiate sweeps, thereby decoupling the vibratory source subsystem from the recording subsystem. By using a continuous recorder and the method of the present invention, the recording trucks and the observers can be eliminated, and the vibratory sources can be initiated more efficiently than conventional systems.

Abstract: A method of more accurate phase encoding of phase offset vibrators used in simultaneous-multiple-sourcing 3D seismic mapping. The method measures the actual input energy and the proxy energy thereby determining a bulk error and a frequency-dependent error, both to be applied to correct the proxy energy. The corrected proxy energy is then used to perform actual seismic survey, and the inversion is then performed using the corrected proxy energy to source separate each vibe where the error is minimized.

Abstract: Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.

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: The invention is an electric seismic vibrator source of the type used in seismic prospecting for hydrocarbons that creates a quasi-impulsive burst of seismic energy onto the ground and into the earth. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground. All of the linear electric motors are driven against the ground in a high power pulse that delivers a band-limited spectrum of seismic energy over a very brief period of time that would like a “pop” and be measured in milliseconds. A quasi-impulsive seismic pulse would create a wave field that resembles the seismic data acquired using dynamite or other explosive seismic systems without the ultrahigh frequencies of a true explosive pulse. The quick burst or several quick bursts may further speed up the survey by minimizing the time that a vibe spends on a source point.

Abstract: The invention is an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. The seismic source further includes an active isolation system that provides for significant weight on the ground through the rods of the linear electric motors, but protects the vehicle body and the remainder of the systems on the seismic source to be insulated from the harshest vibration related to the acoustic energy being applied to the ground. The active isolation system may include reactive elements such as pneumatic and hydraulic shock absorbers, but also includes active elements such as linear motors operated to counteract the impulsive forces from conveying through the frame of the seismic source.

Abstract: An electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons is provided. In one example, the source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. A foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground in a rapid progression, acoustic energy is created and delivered into the ground for geophones to sense and record.
