WebTritium is used as a tracer because it is relatively easy to detect due to its radioactivity. In groundwater studies, tritium-labeled water can be released into the ground at one point, and the amount of tritium-labeled water that appears at other points can be monitored. In this way, the flow of water through the ground can be mapped. WebThis article describes studies conducted at the Samgori-Patardzeuli oil field, located 30-45 km east of Tbilisi in the Soviet Union, on the use of natural tritium as a tracer in determining the hydrology and sweep efficiency of displacement fluids during waterflooding EOR operations on the wells of the field.
