Surface communication apparatus and method for use with drill string telemetry
First Claim
1. For use in an operation of drilling an earth borehole using:
- 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 said drive string for rotating the drive string and the drill string;
a system for generating electric power in the region of the drive string, comprising;
an electric generator that includes a rotating generator component that is mounted on said drive string for rotation therewith, anda stationary generator component that is mounted on a stationary portion of the drilling rig, said rotating generator component producing electric power in the region of said drive string.

Abstract
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.
