Distributed temperature and distributed acoustics deployed by Z-system are excellent for detecting leaks, flow behind pipe and flow out of zone.

Whereas traditional logging methods can only see a point in time, DFO means that all the well can be imaged at the same time. As a result there are not only significant time savings but also intermittent or dynamic leaks can be easily spotted or where an annulus has to be bled down to see a leak it can be seen instantly.
