A drilling system comprises a drillstring including a dill bit, a bottomhole assembly coupled to the drill bit, and a plurality of interconnected tubular members coupled to the bottomhole assembly. A first tubular member includes a communication link having a first annular inductive coupler element disposed in an annular recess in a first end, a second annular inductive coupler element disposed in an annular recess in a second end, and a cable coupling the first annular inductive coupler element to the second annular inductive coupler element. In addition, the drilling system comprises a first signal level determination unit disposed in the drillstring and configured to determine a level of a first signal communicated from the second inductive coupler element. Further, the drilling system comprises an axial load determination unit configured to determine an axial load at the first signal level determination unit based on the level of the first signal.

Systems and methods for detecting drillstring loads

A technique facilitates the drilling of a wellbore by enhancing the ability to relay data. The system comprises a saver sub designed to connect a top drive unit with a wired drill pipe without requiring modification of the top drive unit. The saver sub comprises an electronics package, a battery, and an antenna coupled to a saver sub mandrel.

System and method of using a saver sub in a drilling system

An operation of drilling an earth borehole uses a drilling rig, a drill string of drill pipes having its generally upper end mechanically coupleable with and suspendable from the drilling rig, a drive string portion of the drill string, mechanically coupleable with the topmost drill pipe of said drill string, and a drive mechanism mechanically coupleable with the drive string for rotating the drive string and the drill string. A system for generating electric power in the region of the drive string includes an electric generator, which includes a rotating generator component mounted on said drive string for rotation therewith and a stationary generator component mounted on a stationary portion of the drilling rig. The rotating generator component produces electric power in the region of the drive string.
