Lessons From 10 Years of Monitoring With Chemical Inflow Tracers

Initial development of inflow tracers was designed to provide qualitative information about the location of water breakthrough in production wells. The proof of concept and application for water detection initiated the development of oil tracers for oil-inflow monitoring.

Initial development of inflow tracers was designed to provide qualitative information about the location of water breakthrough in production wells. The proof of concept and application for water detection initiated the development of oil tracers for oil-inflow monitoring. The evolution of inflow-tracer-signal interpretation also has provided valuable insight to inflow characterization. A model-based approach to match the measured signals with proprietary models also has been developed.

Unique Chemical Tracers for Reservoir Surveillance

During the past decade, many unique chemical tracers have been designed.
