Tracer’s ability to quantify mass communication is used to directly prove and quantify flow-back in stimulation operations, such as fracking, acid stimulation and scale inhibitor placement.

Injected stage-wise – one unique oil / water tracer per stage – tracers give direct proof of clean-up of each stage and can also be used to quantify fluid contribution from each stage. Injected in single wells, tracers can also detect possible leaks through annular space or through the near-well reservoir space.
