3:41 The challenge
- →Confirm well trajectory and relative position on a greenfield SAGD pad.
- →The drilling well must pass an observation well at safe separation.
- →Survey uncertainty alone is insufficient for SAGD anti-collision assurance.
Our solution
Torped™ rotating-magnet ranging: gyro-referenced magnetic data captured from the observation well as the drilling BHA passed by, building a composite survey to resolve true relative position and run an anti-collision scan.
Strong signal, zero non-productive time, a first Canadian deployment
The result
±0.38 m
TVD (2σ), true position resolved at pass-by
- ·Clean gyro-referenced data captured at ~12.3 m lateral separation
- ·Anti-collision scan: closest approach ~13.1 m
- ·Revealed the drilling well ~1.7 m lower in TVD than surveyed
- ·All system components performed as expected, zero non-productive time
