Leading Magnetic Design Ltd designs, develops and manufactures custom-built electromagnetic telemetry systems. Our products are used worldwide in the oil & gas industry. Our Electromagnetic Measurement-While-Drilling (EM MWD) technology provides the ideal solution for telemetry during underbalanced drilling.

  • Leading Magnetic design develops and produces custom-built, versatile EM systems for use in a variety of field conditions. Our products include the Twin EM MWD tool which works alongside existing MWD, and the DST SRO wireless surface readout for drillstem testing.

  • LMD's durable and rugged EM equipment is designed in accordance with latest leading-edge scientific theory. Our high quality technical team are expert in all aspects of electromagnetism, signal generation and detection; our products are designed from first principles, leading to optimal performance across the board.

  • LMD carries out pioneering hi-tech Research & Development and provides intelligent software solutions. We are happy to provide custom EM solutions tailored to your needs. In addition to user-cutomised tools, this allows us to design add-on EM compatible with the exact MWD interface you are using.

Faraday-Link magnetic telemetry for short and medium hop

Leading Magnetic Design are proud to introduce their latest downhole wireless communications solution - Faraday-Link, providing true downhole connectively across a range of environments and applications using Magnetic Inductive Telemetry.

Robust wireless data transmission for static and dynamic applications including MWD, RSS, logging, intelligent slickline and smart completions.

  • Strong yet efficient magnetic transmitter in combination with highly sensitive magnetic receiver is able to transmit across metallic barriers including behind casing/tubing and across plugs, packers and mud motors.
  • Works in all well media and is not affected by the formation, completion or by well fluids including drilling mud or produced fluids.
  • Battery or wired power for maximum flexibility.
  • Bespoke packaging to suit individual application needs and technology footprint.
  • Transparent data bridge with data transmitted and received in its native format for rapid tool integration.
  • Already being used in drilling and smart completion applications.
  • Patent pending.
