Reservoir Monitoring

Our water and oil tracers can be used to characterize and monitor oil or geothermal reservoirs by tracking the movement of fluids in the subsurface. Thanks to its design and performance, Haelixa tracer implementation in geothermal/oil fields allow operators to gain a complete knowledge of the reservoir and of how it develops over time, assisting in engineering and management decisions. We can perform complex multi-tracer studies to obtain a high resolution map of a reservoir. Smart tracers capable of monitoring fluid parameter such as temperature are available, combining in an innovative way tracing and remote sensing. The high quality information obtained with our platform brings reservoir description to the next level, allowing to wisely plan production and development activities, maximizing productivity, and minimizing cost and environmental impact.

 

 

Case study

Among the trials performed in 2017, one has been executed at the Deep Underground Geothermal (DUG) Laboratory located at the Grimsel Test Site, southern Switzerland, where geothermal energy-related investigations are being conducted. Mixtures of different fluorescent dyes and Haelixa tracers were injected into boreholes and samples were collected at different locations. Results were used to build a hydraulic conductivity map of the site. The trial not only proved the technology readiness and field applicability, but also the superiority over competitive tracer dye technologies in terms of:

 

Resolution - the higher number of distinct tracers than dyes results into increased map resolution and result quality

Sensitivity - 10 - 100x lower detection limit than dyes

Reliability - no background problems generated from tracers injected during previous tests (the tracer "fingerprint” can be renewed each time)
