How to retrieve a grain of sand?
A tracer is a substance that always follows a desired path and can easily be retrieved. This technology is developed by IFEs scientists, and has showed itself to be of great value when extracting oil.
IFE researchers inject tracers into the oil wells to measure the amount of water and follow the oil movements. When the tracer is retrieved in an oil well, it’s possible to understand which path the water or oil comes from. This means we can learn more about the patterns, which will contribute to increased oil development and better understanding of the flow in the reservoir.
IFE develops and uses computer programs that use results from the tracer to improve visual models of the reservoirs. Tracer technology contributes to lower emissions of produced water for the environment, since the tracers identify where the water produced together with the oil comes from.
To see this technology in perspective, it can be compared to finding a gray grain of sand in a gymnasium filled to the ceiling with equally large white sand grains with a diameter of 1 millimeter. Such a chemical analysis gets done in 30 minutes in IFEs laboratory.
