Terre-LP Mud Pulse MWD Tool
Bottom-Landed Linear Pulser | A Classic Perfected
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.
Key Features
Hours on One Battery
Improved Battery Consumption
Terre-LP MWD tool will work up to 600 hours on one battery, compared to 400 hours of our leading competitors. As a result, there will be fewer battery changes in the field that lead to costly Non-Productive Time (NPT).
Additionally, wireline retrievability allows you to make battery changes without tripping (retrieving the entire pipe-run). Which, otherwise, could cost you several days of inactivity.
These are some of the many ways MWDPlanet helps you be efficient in the field.
Operational Hours at Max Temperature
Extended Use at High Temperatures
Due to power consumption design changes, Terre-LP’s internal operation does not contribute to internal heat increases. This means that the life expectancy of your MWD tool at its maximum recommended temperature rating goes up from 1000 operational hours to 2000.
Range of Accuracy of Inclination
Range of Accuracy of Azimuth
Improved Sensor Pack Accuracy
The exceptional sensitivity of our sensors to the magnetic and gravitational fields combined with reduced internal noise levels allow for accuracy of inclination within the ±0.1° range and accuracy of azimuth within the ±0.2° range.
These results are among the top performers in the field, ensuring you reach your goals.
Mechanical Parts MTBF Underground (Hours)
Extended Mean Time Between Failures (MTBF)
Terre-LP’s design makes it a reliable MWD tool in many ways. Notably, Terre-LP’s easier workflow allows for less possibility for human error. As a result, your mud pulse tool will fail less often. Equally important, the four-year average MTBF of the mechanical parts, which experience the most wear, is above 2,500 hours of underground performance.
Virtually Impossible Data Loss
Transmitter Design Changes
You will never lose your data. Data corruption can lead to a full operational stop, preventing you from reaching your goals. Our design modifications and increased data update rate will make sure your data is safe.
Specifications That Cover 99% of Drilling Conditions
In times of many unknowns, proven and familiar MWD technology can be an irreplaceable assurance. A dependable and versatile mud pulse tool that both you and your personnel are familiar and comfortable with deserves a spot in every fleet.
Investing in MWD technology that will be the right choice 99% of the time, is as good as any investment can get.
