Terre-LP Mud Pulse MWD Tool
Terre-LP Mud Pulse MWD Tool
Brand: MWDPlanet and Lumen CorporationWhen 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.
