Patent ID: 7704746

Claim:
A method for the measurement of carbon dioxide leakage rate from sequestration reservoirs, the method comprising: A). Adding tracer molecules selected from the group of sulfur containing compounds, halogen containing compounds, hydrocarbon compounds, perfluorocarbon compounds and inert gases to carbon dioxide at a predetermined molar ratio; B). Allowing the tracer molecules and carbon dioxide to mix homogeneously; C). Injecting the homogenous mixture of tracer molecules and carbon dioxide into sequestration reservoirs; D). Collecting leaked tracer molecules onto a sorbent during a known time period onto sorbents specific for retaining the tracer molecules at or near injection points, fracture zones, formation outcroppings, areas around an underground carbon dioxide plume soil atmosphere interface, aerial collection towers, unmanned aerial vehicles and freshwater aquifers and wells; and, E). Measuring concentrations of both the collected tracer molecules and carbon dioxide to determine the rate of carbon dioxide leakage over a period of time.
