Terre-Flex Multi-Channel MWD System
Intelligent EM/MP Channel Selection | Always The Best Data Transmission Path
Speed and accuracy are invaluable assets on a drill site. Assets that result in savings of hundreds of thousands of dollars by reducing wait-time and costly fixes due to errors. The last thing you want to do is pull out your entire string to switch your MWD telemetry because the demands suddenly changed. And yet, it is not an unlikely situation in the field – predictions only go so far.
Clearly, the best solution is intelligent, automatic channel selection. Terre-Flex is a multi-channel, intelligent MWD system that proactively selects the best data transmission path, whether Electro Magnetic (EM) or Mud Pulse (MP), which ensures that no matter how the formations or the mud mix change, you and your data are always covered.
Key Features
Times Faster Data Rate Than Standalone MP Channel
Faster Data Rate
The data rate of combined MP and EM channels is up to 32 times faster than a standalone MP channel data rate. When speed and accuracy are the most invaluable assets, results like these will take your drilling experience to the next level of efficiency.
Intelligent EM vs MP Channel Selection
Intelligent Proactive Channel Selection
Terre-Flex multi-channel MWD tool picks out the best transmission channel at any given moment, between electro-magnetic waves and hydraulic mud pulses, to send data. Both independent of the quality of your mud mix and the characteristics of earth formations, you will always receive accurate and high-quality data.
In short, the quality of your data is no longer tied to the mud mix or earth formations.
Days of Wait-Time Saved Over One Month of Drilling
Immediate Surveys
Tired of waiting for the pumps to cycle through every time a new pipe segment is attached? Now you don’t have to – surveys are available instantly on connection.
That extra five minutes your team has to be on standby whenever a change is made adds up to a week of wait-time over a month of drilling. Terre-Flex will ultimately save you hundreds of thousands of dollars over the course of one job.
Little to No Service Necessary
Cost-Effective Service
Terre-Flex’ build is a unified, small assembly. As an illustration, we engineered a multi-channel tool in the dimensions of a conventional mud pulser. Minimal amount of mechanical parts drastically diminishes the number of elements that could fail and would require service.
As a result, Terre-Flex MWD System requires little to no service, allowing you to save time and money, while focusing on results.
No Signal Too Weak To Decode
Superb Signal Decoding from Noise
Terre-Flex’ EM channel is able to decode signal weaker than the noise floor. This is achieved by using the frequency range of 1-32 Hz, four times the industry average, and outputting signal strength at least double the industry average at 80-100W. As is our practice, we are ensuring that you will not miss a bit.
- Terre-Flex’ EM Transmitter 96%
- Industry Average Power Efficiency 50%
Unparalleled Power Efficiancy
Thanks to our patented IP, the power efficiency of Terre-Flex’ EM transmitter is almost twice that of the industry standard. This feature ensures your wait-times and costs are even more minimized by reducing the frequency of battery changes.
New Philosophy
Terre-Flex is built on a whole new philosophy of MWD system architecture with its multi-channel input-output, modular hardware and software design, and proactive signal control. Terre-Flex not only chooses for you the best data signal path, but it is also able to decode weak signal strengths. For you this simply means reliable and accurate data, always.
