Pulse real time directional and gamma ray data in slim holes without delay and enhance reservoir understanding, accurate well placement and maximize production
Slimhole Stepper Pulser modulates the flow of drilling fluid, encoding downhole data in positive pressure pulses that propagate up the drill string and are detected by pressure sensors at surface
Extensive applications
- Drill longer laterals with increased signal detection range
- Increase BHA longevity for longer runs through good signal detection
- Capable to optimize the stratigraphic placement of laterals
- Make better geosteering decisions from faster and continuous gamma and directional pulsed data
- Resistant to shock (1000g/ 0.5 ms) and vibrations (25g RMS 30-500Hz Random, 30g 50-300Hz Sine) so a better choice for harsh drilling environment
- Increase drilling efficiency with wide flow rate ranges
