Reelwell-Telemetry System
Reelwell has developed a new and unique type of real time drillpipe telemetry system. The system enables 2-way high speed data communication to downhole MWD/LWD tools. In addition it offers the ability to transfer large amounts of electric power to downhole tools.
The system was originally developed in combination with the Reelwell Drilling Method (RDM) by using the dual drill pipes as electrical conductors, however, the system is equally beneficial to conventional drilling. The system is based on dual concentric drill strings and comprises a unique stab-in connector design that is mounted in the drillpipe toolboxes and an advanced transceiver technology that sends and receives sensor data.
The connector system provides three important functions in a highly robust and space saving design; electrical insulation, high pressure seal and low impedance electrical contact. No parts protrude from the drill pipe, which can be handled just like any other drill pipe. The transceivers utilize digital signal processing technologies to optimize signal transmission. The data to be sent is made redundant by duplication and interleaving, both in time and frequency. This makes the system immune to all noise sources. The high data bandwidth provided by the system allows any combination of downhole sensors to be monitored continuously. The power supply capability exceeds the requirements of signal transmission for all existing sensor or directional drilling tools.
