The Diagnostix* Well Integrity Platform comprises a suite of tools that may be deployed with or without fiber optic cables to survey, monitor and assess wellbores. By combining multiple optical fibers and a copper wire electrical conductor in the same armored cable, distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) surveys may be conducted along with cement bond, corrosion and production logging tools to improve drilling, completion and production decisions. Unlike conventional cased hole wireline measurements, DTS/DAS technology allows the entire wellbore to be simultaneously surveyed in real time to detect and monitor downhole events that standard tools may not identify. Applications include:
- Leak detection
- Well integrity monitoring
- Enhanced production logging
- Production and injection well profiling
- Artificial lift optimization
- Well interference
