Abstract

In an embodiment of the present invention utilizes a frac plug having a large diameter through bore wherein the through bore is at least 75% of the outer diameter of the plug. A tracer assembly is then affixed to a lower end of frac plug. The frac plug tracer assembly is run into a wellbore where the frac plug is then set, perforated, and fracked. The obstruction within the frac plug through bore is then removed. In some instances, the instruction may be a ball, dart, or other obturator and in some instances the obstruction may be a dissolvable plug. With the obstruction within the frac plug through bore removed wellbore fluids from the hydrocarbon formation may flow upward through and around the tracer assembly picking up chemical traces which are then carried to the surface to be analyzed.
