Licensed exclusively from Shell in September 2019 after many years of research and testing, this game-changing “At Bit” steering system has successfully demonstrated the ability to build significant angle while drilling.
Enteq brings a proven track record of design, engineering and manufacture of robust and reliable MWD solutions for high temperature conditions, with integration/connectivity to Near Bit measurements, LWD and EM / Pulser communication. The engineering team dedicated to the RSS has considerable experience with previous successful systems and has performed comprehensive re-modelling and validation of flow / physical effects. A thorough re-design of mechanical components and control system has been undertaken in order to deliver a tested and proven down-hole ready solution.
This Rotary Steerable System is being introduced as a simple, high performance, reliable, low cost ‘At Bit’ drilling solution.
The tool deploys a patented novel method of steering utilising forces generated by pressure differentials at the bit. The system will deliver a clean trajectory, eliminating tortuosity, at a significantly reduced operating cost.
|No control system limitations – decoupled from pipe-rotation||No Driveshaft – All WOB transferred through internal collar||Full 175℃ system (prototype initially 150℃|
|Decoupling significantly reduces torsional vibration (excellent for MRSS)||No external collar material machined away||Solution for high-temperature and geothermal market|
|Max RPM dictated by bit specifications only||No external “hanging” points – low LIH risk|
