ABSTRACT:
A method and apparatus for injecting radioactive tagged sand into fluids used in hydraulic well fracturing, or acidizing, operations, the fluids being pumped under high pressure into the well bore by a high pressure pump, wherein the radioactive tagged sand does not contaminate the high pressure pump, and the pressure between the high pressure fracturing fluids and/or acidizing fluids and the radioactive tagged sand is equalized, whereby it is not necessary to overcome the high pressure present in the system.
