Twin Telemetry: EM Measurements While Drilling
Leading Magnetic Designís Twin system is the first true twin MWD. Twin does not require tripping or switching between mud pulse and EM, instead the EM runs in parallel with industry-standard Tensor-compatible mud pulse. Twin is ultra power-efficient, autonomous, high output, high speed, and temperature-rated to 165C. The system is rugged, reliable, and field-proven, with field support provided by our partners Drill Tek MWD. All the advantages of EM can now be obtained at a fraction of the cost. Our latest advanced data coding allows effective throughput of 10 bits per second.

Why use EM?
Investing in twin telemetry
Twin allows re-using existing Industry standard MWD sensors and surface unit with an EM tool: compatibility with the existing mud pulse system makes our system easy and straightforward to use. The mud pulse and EM complement each other, providing redundancy and ensuring your telemetry continues to operate to TD, regardless of depth, formation, the mud pressure, or the LCM content.
