DEFINITION

Classification: 73/152.59

By measurement of response due to force:

(under subclass 152.54) Subject matter wherein the determination of the physical characteristic of the borehole, the casing, or the drill rigging is made by measuring a response due to an agency or an influence that if applied to a free body results chiefly in acceleration of the body and sometimes in elastic deformation.
