Challenge: Determine water inflow source behind tubing in an ERD well to guide future workovers and aid in new well design.
Solution: Use the four-drive TuffTRAC iX cased hole services tractor to efficiently navigate in 3½-in completion while conveying Pulsar multifunction spectroscopy service to acquire production and WFL water flow logs.
Results:
- Successfully achieved target depth of 10,700 m in a single run in 80% less time than conventional tractors to save rig time
- Obtained advanced spectroscopy and WFL logs that unambiguously identified the point of water inflow
