DEFINITION

Classification: 73/152.48

Force:

(under subclass 152.46) Subject matter wherein the determination of the physical characteristic of the borehole, the casing, or the drill rigging is made by measuring an agency or an influence that if applied to a free body results chiefly in acceleration of the body and sometimes in elastic deformation.

152.49, for a measurement of force to determine a physical condition of a borehole, a casing, or a drill rigging while drilling.

152.59, for the downhole measurement of force to determine a physical condition of a borehole, a casing, or a drill rigging.

760+, for stress or strain measuring or testing by stress or strain.
