Abstract: An acoustic sound source designed to impart vibratory energy into its surrounding environment by linearly displacing transducer face plate(s) that are coupled to a rotary motor via crankshaft/connecting rod(s) or camshaft(s). The frequency of the vibrational energy is proportional to the speed of the rotary motor and the amplitude of the vibrational energy is proportional to the linear displacement of the transducer faceplates. The motor can be manually or automatically controlled to operate at a fixed speed and/or a variety of time varying speeds such as frequency sweeps or ramps. The linear displacement or amplitude of the transducer faceplates can also be manually or automatically controlled to operate at a fixed displacement or to have the displacement vary with time and/or frequency.

Abstract: A multitude of seismic sources are formed into a linear array which can be permanently cemented within a wellbore. The seismic sources can be orbital vibrators that are electrically connected and protected from the cementing by use of pieces of drill pipe and tubing that are interconnected and provide a container for electrical connection of the seismic sources and provide surface access through a surface vault.

Abstract: A vehicle hitch or tow bar can be used as an attachment point to a vehicle to provide weight to a seismic source system which includes at least one vibratory seismic source mounted to a shaft of pole and a mechanism for raising and/or lowering the shaft or pole for use in coupling a seismic source to the earth in conjunction with acoustic receivers for determining the lithology and for acoustic imaging of the subsurface of the earth.

Abstract: A seismic source system uses at least one seismic source, a screw in piling ground anchor installed into the earth/ground and means of coupling the energy from the seismic source to the screw in piling ground anchor.
