    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: 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: 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.

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. Preferably 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 to create impulses that deliver acoustic seismic energy into the earth for geophones to sense and record. However, the pulses of seismic energy are delivered in a distinctive fashion where different linear motors are deliberately and concurrently providing different signals that create a distinctive composite signature or signal that can be identified in the data record for source separation purpose.

    Abstract: The invention is an electric power accumulator used with 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 to drive a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion. The source may also be designed to use electric power to drive the source from location to location through a survey area. A large electric power accumulator is provided to store electric power when the generator is able to produce excess power and the accumulator may deliver power along with the generator to drive the rods and deliver acoustic energy. With a large electric power accumulator, such as a battery or capacitor, the engine and generator combination may be engineered to be somewhat smaller, less costly and more efficient than a system where the engine and generator were sized to provide the electric power at times of maximum electric draw.
