This invention relates generally to the field of seismic exploration and more particularly to an improved apparatus for imparting vibrational energy to the earth wherein selected combinations of compressional and shear wave energy can be generated simultaneously. In applicant's co-pending commonly assigned U. As described in the subject application a hydraulic vibrator for providing reciprocal vibrations along a vibratory axis is supported above and independently of an earth-contacting base plate. Preferably the vibrator is of a conventional type wherein a reaction mass is slidably mounted on a double rod end piston. Introduction of hydraulic pressure within such vibrator produces significant reciprocation of the piston. Means are provided for variably orienting the vibrator so that such vibratory axis is directly along any predetermined slant path.

E&P Exploration: Clarifying Seismic Distortion | Hart Energy

A marine seismic acoustic signal generator is installed in a small, substantially zero-draft marine support vehicle that is usually towed behind a service ship in a body of water. In operation, the entire vehicle becomes an acoustic wavefield generator. As is well known to geophysicists, a sound source, at or near the surface of the earth, is caused periodically to inject an acoustic wavefield into the earth at each of a plurality of regularly-spaced survey stations. The wavefield radiates in all directions to insonify the subsurface earth formations whence it is reflected back to the surface to be received by seismic sensors receivers. The seismic sensors are located at designated stations at or near the surface of the earth.

EnviroVibe 2 Seismic Vibrator Production System

A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite , or it can use more sophisticated technology, such as a specialized air gun. Seismic sources can provide single pulses or continuous sweeps of energy, generating seismic waves , which travel through a medium such as water or layers of rocks. Some of the waves then reflect and refract and are recorded by receivers, such as geophones or hydrophones. Seismic sources may be used to investigate shallow subsoil structure, for engineering site characterization, or to study deeper structures, either in the search for petroleum and mineral deposits, or to map subsurface faults or for other scientific investigations.

A seismic vibrator is a truck-mounted or buggy-mounted device that is capable of injecting low-frequency vibrations into the earth. It is one of a number of seismic sources used in reflection seismology. Today, seismic vibrators are used to perform about half of all seismic surveys on land. A seismic vibrator transforms the energy provided by a diesel engine into a vibration.
