• Nonradioactive chemicals

How they improve performance

Resman™ stimulation tracers are deployed stage-by-stage or zone-by-zone during hydraulic fracturing or acidizing operations. By tracking their return during flowback, operators can quantify zonal contributions and diagnose fracture-driven interactions to optimize completion decisions.

Use these tracers for

• stage- and cluster-level production logging
• stimulation fluid cleanup monitoring
• assessing fracture uniformity, durability, and connectivity.

How they work

Tracers are deployed either in polymer rods as part of the completion string or seamlessly blended into stage, stage cluster, or zonal treatments. In either case, the stimulation or fracturing process transports the tracer into the formation. During flowback and production, fluid samples are captured at surface at a frequency agreed with the operator and analyzed with a resolution of parts per trillion.

Resman stimulation tracer signals are plotted against time, a dissimilar tracer, or both, for advanced analysis. The resulting curves are then interpreted, often together with other relevant data. The value comes from interpreting the tracer journey, a task that we have simplified with advanced digital workflows that use the direct measurements as input.

Proprietary interpretation methods are used to generate a quantitative production log (QPL) of stage, cluster, or zonal performance. Appearance of tracers in a different place (e.g., in an offset or infill well) compared with where they were introduced provides proof of mass transport and connectivity. Results are subsequently presented via our Tracer Track™ visualization solution, where applicable..
