Abstract
The present disclosure is directed to a method and apparatus for controllably injection a radioactive isotope tracer fluid into a fracture fluid, a manifold or mud flow line connected to a well. It is best used in measuring well stimulation procedures based on injection of tracer isotopes so that stimulation performance data can be obtained by gamma ray spectroscopic measuring instruments lowered in the well borehole after fracture. The present apparatus utilizes a tank supply of tracer fluid connected through a pump into the mud line wherein the pump drives a tachometer, and utilizes a CPU to respond to pumping rate measurements and adjust the pumped rate of the tracer fluid.
