Teledrift – Inclination-only MWD

Teledrift - Inclination-only MWD

Teledrift is an inclination-only mud pulse MWD system that can measure inclinations up to 10.5ยบ. The system is available from Scientific Drilling International (SDI).

The Teledrift is a purely mechanical system. The tool consists of a pendulum at the bottom that moves along a series of graduated stop shoulders, and a signalling plunger at the top that can traverse a series of seven annular restrictions to produce pressure pulses in the mud stream.

The plunger travel is controlled by the coding system so that as . . .
