First FLI deployment in Papua New Guinea identifies tubing leaks in an onshore gas well.

We've completed our first FiberLine Intervention (FLI) project in Papua New Guinea, as demand for our technology in the Asia Pacific region continues to grow.

In this project FLI was used to quickly identify the location of active tubing leaks in an onshore gas well. The FLI probe was gravity deployed to its target depth in just 13 minutes, laying bare distributed acoustic sensing (DAS) and distributed temperature sensing (DTS) fibre across the zone of interest. Annular pressure was manipulated while the dynamic acoustic and temperature signature throughout the wellbore was continuously measured.

Multiple tubing leaks were successfully identified by FLI and their locations were precisely pinpointed. Each was monitored, measured and ranked in order of magnitude to inform a suitable remediation plan for the operator where tubing straddles would be set and well integrity restored.

FLI’s small wellsite footprint and high-quality data is ideally suited to remote operations such as these, with all the equipment mobilised by air, sea or land at short notice and transported to the wellsite by a field engineer in a light vehicle.
