Graphical Solution Of Concentration At Production Wells Of Injected Radioactive Water Tracers, George E. Vaughn Jr.

Masters Theses

"With the advent of field research in which radioactive isotopes are used as tracers for water injected in secondary-recovery operations, knowledge of the probable transit time between wells of an injected tracer, its concentration at detection points, and the resultant optimum injection concentration has become important. Both detection and, consequently, injection concentrations of radioactive tracers are at least in part functions of the loss of tracer for various reasons, flow characteristics between wells, the rate of decay of radioactive emission, and the sensitivity of the detection apparatus. A method, based on the characteristics of a homogeneous 5-spot system, has been …
