Spectrum Tracer Services (STS) utilizes 3 different tracer techniques for different completion diagnostics. Currently, we have 42 water soluble tracers (FFIs), the most available on the market at this time. This allows for additional unique identifiers when the fracture contains many stages, or when looking for communication between wells. Oil soluble tracers (OST) are the latest technological advancement in our product line. Spectrum's OSTs are a solid particulate, not a liquid. We currently have 34 unique OSTs available, with several more in the development and testing stages. Additionally, when it comes to evaluating proppant placement and/or perf cluster design, we provide the 3 standard RA tracers complemented by our logging services.
