Among well monitoring technologies, tracers stand out as the only one that directly proves mass communication. When unique RESMAN tracers are installed at specific locations along the well-bore, detection of a tracer proves fluid communication from the installation point to the sampling point. This feature is exploited directly to identify leaks across packers and barriers, to verify plug-and-abandonments (P&A) and to verify water shut-off.
For wells installed with sliding sleeves e.g., installed tracers can prove or disprove successful sleeve positioning – if inflow control devices (ICVs) are installed the tracers can verify ICV actuation. In this manner RESMAN’s installed tracer systems provide efficient de-risking of projects and wells where verification of seal integrity is important.
