A new conceptually simple method to measure the liquid inventory of a pipeline is presented. The method is based on tracer technology and includes simultaneous measurements of condensate and MEG/water content by what is essentially residence time measurements. The method is effectively non-intrusive, and no pigging is involved. Measurements of liquid accumulation in gas-condensate pipelines are presented. Selected radioactive tracers have been used to measure both the water and condensate volumes in two offshore pipelines at different flowing conditions.
