When drilling conditions match the difficulties of the economic environment, each equipment purchase becomes an investment. Consequently, the market demands versatile and proven technology: something you can repeatedly count on.

With this in mind, we have perfected the design of the conventional mud-pulse based MWD technology. Thus allowing you to drill longer, achieve less NPT, and get more accurate results.

Featuring improved connectivity between segments and more efficient power consumption, Terre-LP mud pulse MWD tool is easy to integrate into your existing workflow.
Features
  • Works with a wide variety of drilling pipe diameters for any drilling conditions.
  • Coverage of the entire spectrum of drilling fluid volume.
  • Allows you to rescue your entire telemetry string from underground in emergency situations.
  • Adds a convenient way of changing batteries that does not require the retrieval of the entire drilling pipe.
  • Small sizes allow for easier and faster retrieval.
  • More reliable and stable than pressure-based switches.
  • The short length makes Terre-LP easier and safer to operate. Additionally, interfacing with other LWD equipment will not significantly increase the length of the entire assembly.
  • Will work with pipes collar sizes as small as 2 7/8 in diameter.
  • Most reliable power-source. Notably, can be modified to a turbine-alternator hybrid.
