Things You Should Know About Teledrill’s Newton System
- Only Teledrill’s Newton system provides extended reach capability and both real-time and recorded downhole data measurements.
- Most coiled tubing operations are conducted without direct measurement of downhole parameters that influence performance during plug milling, annular fracking and well intervention. This lack of information prevents full optimization of coiled tubing operations.
- Now the Newton system provides reliable measurements of downhole parameters in real time so coiled tubing operators can make informed decisions to avoid problems, optimize drill out performance, and maximize hole cleaning.
- Coiled tubing string replacement is one of the highest costs for CT operators in unconventional well completions. Because coil life is a function of its unreeling and reeling, excessive coil movement can create premature fatigue and shorten coil life. Teledrill’s Newton system provides downhole measurements that enable drill-outs and hole cleaning with a minimum number of short trips, extending coil life and saving money for coiled tubing providers and oil company operators.
- The Newton system’s unique operating principle uses the force generated by its internal pulser both to deliver axial thrust to advance the coil and to send pressure pulses up the fluid column carrying downhole sensor data.
- The system’s electronics utilize the latest high pressure / high temperature components and are rated to 175⁰C. A state-of-the-art processor provides the computing power needed for continuous acquisition, recording and transmission of downhole sensor data, as well as precise pulser valve control.
- The Newton system enables real-time monitoring of weight-on-bit, differential pressure, inclination, gravity tool face and temperature, so coiled tubing operators can make quick, informed decisions to control drilling, keep the hole clean, and minimize short trips.
- While the tool can be programmed to transmit any combination of data to the surface, Teledrill recommends transmitting only the data that is critical for enabling operating decisions to optimize performance and cost for the given operation. During plug milling, weight on bit, and differential pressure are most important.
- The Newton system stores data from all of its sensors in memory until the tool is returned to the surface and the data are downloaded.
- These data are correlated with well depth and provide a basis for analyzing the job and evaluating bit, motor and coiled tubing unit performance. This evaluation enables completion engineers to optimize vendor selection and improve plug milling operations on subsequent wells.
- During operation, the pressure drop across the Newton system is only 300 – 400 psi, compared to up to 1,750 psi for vibration tools , at comparable flow rates, so more hydraulic horsepower is directed to the downhole motor to generate drilling torque and maximize flow rate for a given surface pressure limit.
- Unlike vibration tools and other thruster devices that operate continuously, the Newton™ system thruster can be turned on and off from the surface, so it can be utilized in the portions of the well where it is most needed.
- By shortening the tool’s operating time, stress on the coiled tubing and BHA is reduced, preventing damage to the string, connections, and motor.
- Teledrill’s Newton system has the widest flow rate operating range of extended reach tools on the market, 2 – 5 bbl/min.
- While other tools are designed to perform well at a single specified flow rate, the Teledrill system operates consistently at any point within the flow rate range.
