Seismic wave generation systems and methods for cased wells
First Claim
1. A vibration source, comprising:
- an elongate armature bar;
a driver positioned about the armature bar, wherein the driver is movably coupled to the armature bar and comprises an electromagnet;
a clamping unit adapted to removably couple the armature bar to a surface of an object; and
wherein during operation the electromagnet is activated such that the driver moves with respect to the armature bar and a vibratory signal is generated in the armature bar.

Abstract
A vibration source (10) includes an armature bar (12) having a major length dimension, and a driver (20A) positioned about the armature bar. The driver (20A) is movably coupled to the armature bar (12), and includes an electromagnet (40). During operation the electromagnet (40) is activated such that the driver (20A) moves with respect to the armature bar (12) and a vibratory signal is generated in the armature bar. A described method for generating a vibratory signal in an object includes positioning the vibration source (10) in an opening of the object, coupling the armature bar (12) to a surface of the object within the opening, and activating the electromagnet (40) of the driver (20A) such that the driver moves with respect to the armature bar (12) and a vibratory signal is generated in the armature bar and the object.
